Unit2 AAmerica is experiencing a major epidemictoday.现今美国正在经历一场重要的流行病。

Unlike epidemics of the past, it is not a disease transmitted by bacteria or viruses.不同于过去的流行病,它不是由细菌或病毒传染的疾病。

This epidemic is an increase in diseases and problems related to stress, and it touches all of our lives.这个流行病的增加是与压力有关的疾病和问题引起的,它涉及我们生活的方方面面。

In 1900 t he average life expectancy in this country was 47, and the major killer diseases included tuberculosis pneumonia,influenza, cholera, typhoid, and smallpox ——infectious diseases which struck people of all ages, regardless of their lifestyle.1900年,这个国家的平均预期寿命为47岁,其主要致命疾病包括肺结核肺炎,流行性感冒,霍乱,伤寒,天花-这些传染性疾病袭击了所有年龄层的人,不管他们的生活方式怎样。

Today,on the other hand,life expectancyhas been extended to 74, thanks in large part to the conquest of the acute infectious disease through improved sanitation, better distribution and storage of foods, and the introduction of immunization and antibiotics.如今,在另一方面,预期寿命已延长至74岁,这在很大程度上是由于对于急性传染病的征服,通过改善卫生条件,更好地分配和储存食物,以及引进免疫方法和抗生素。

A generalisation, a simplification and some applications of paillier’s probabilistic publi

A Generalisation,a Simplification and someApplications of Paillier’s ProbabilisticPublic-Key SystemIvan Damg˚ard and Mads JurikUniversity of Aarhus,BRICS⋆Abstract.We propose a generalisation of Paillier’s probabilistic publickey system,in which the expansion factor is reduced and which allowsto adjust the block length of the scheme even after the public key hasbeenfixed,without loosing the homomorphic property.We show thatthe generalisation is as secure as Paillier’s original system.We construct a threshold variant of the generalised scheme as well aszero-knowledge protocols to show that a given ciphertext encrypts oneof a set of given plaintexts,and protocols to verify multiplicative relationson plaintexts.We then show how these building blocks can be used for applying thescheme to efficient electronic voting.This reduces dramatically the workneeded to compute thefinal result of an election,compared to the previ-ously best known schemes.We show how the basic scheme for a yes/novote can be easily adapted to casting a vote for up to t out of L can-didates.The same basic building blocks can also be adapted to pro-vide receipt-free elections,under appropriate physical assumptions.Thescheme for1out of L elections can be optimised such that for a certainrange of parameter values,a ballot has size only O(log L)bits.1IntroductionIn[9],Paillier proposes a new probabilistic encryption scheme based on compu-tations in the group Z∗n2,where n is an RSA modulus.This scheme has somevery attractive properties,in that it is homomorphic,allows encryption of many bits in one operation with a constant expansion factor,and allows efficient de-cryption.In this paper we propose a generalisation of Paillier’s scheme using computations modulo n s+1,for any s≥1.We also show that the system can be simplified(without degrading security)such that the public key can consist of only the modulus n.This allows instantiating the system such that the block length for the encryption can be chosen freely for each encryption,independently of the size of the public key,and without loosing the homomorphic property.The generalisation also allows reducing the expansion factor from2for Paillier’s orig-inal system to almost1.We prove that the generalisation is as secure as Paillier’s original scheme.We propose a threshold variant of the generalised system,allowing a number of servers to share knowledge of the secret key,such that any large enough subset of them can decrypt a ciphertext,while smaller subsets have no useful information.We prove in the random oracle model that the scheme is as secure as a standard centralised implementation.We also propose a zero-knowledge proof of knowledge allowing a prover to show that a given ciphertext encodes a given plaintext.From this we derive other tools,such as a protocol showing that a ciphertext encodes one out of a number of given plaintexts.Finally,we propose a protocol that allows verifica-tion of multiplicative relations among encrypted values without revealing extra information.We look at applications of this to electronic voting schemes.A large number of such schemes is known,but the most efficient one,at least in terms of the work needed from voters,is by Cramer,Gennaro and Schoenmakers[4].This protocol provides in fact a general framework that allows usage of any proba-bilistic encryption scheme for encryption of votes,if the encryption scheme has a set of”nice”properties,in particular it must be homomorphic.The basic idea of this is straightforward:each voter broadcasts an encryption of his vote(by sending it to a bulletin board)together with a proof that the vote is valid.All the valid votes are then combined to produce an encryption of the result,using the homomorphic property of the encryption scheme.Finally,a set of trustees (who share the secret key of the scheme in a threshold fashion)can decrypt and publish the result.Paillier pointed out already in[9]that since his encryption scheme is homo-morphic,it may be applicable to electronic voting.In order to apply it in the framework of[4],however,some important building blocks are missing:one needs an efficient proof of validity of a vote,and also an efficient threshold variant of the scheme,so that the result can be decrypted without allowing a single entity the possibility of learning how single voters voted.These building blocks are precisely what we provide here.Thus we immedi-ately get a voting protocol.In this protocol,the work needed from the voters is of the same order as in the original version of[4].However,the work needed to produce the result is reduced dramatically,as we now explain.With the El Gamal encryption used in[4],the decryption process after a yes/no election pro-duces g R mod p,where p is prime,g is a generator and R is the desired result. Thus one needs to solve a discrete log problem in order tofind the result.Since R is bounded by the number of voters M,this is feasible for moderate size M’s.√But it requiresΩ(M L−1),and so is prohibitively expensive for elections with large L.In the scheme we propose below,this work can be removed completely.Our decryption process produces the desired result directly.We also give ways to implement efficiently constraints on voting that occur in real elections,such asallowing to vote for precisely t out of the L candidates,or to vote for up to t of them.In each of these schemes,the size of a single ballot is O(k·L),where k is the bit length of the modulus used1.We propose a variant using a different technique where ballots have size O(max(k,L log M)·log L).Thus for k≥L log M,this is much more efficient,and even optimal up to a constant factor,since with less than log L bits one cannot distinguish between the L candidates.Furthermore this scheme requires only1decryption operation,even when L>2.2Related WorkIn work independent from,but earlier than ours,Fouque,Poupard and Stern [6]proposed thefirst threshold version of Paillier’s original scheme.Like our threshold scheme,[6]uses an adaptation of Shoup’s threshold RSA scheme[10], but beyond this the techniques are somewhat different,in particular because we construct a threshold version for our generalised crypto system(and not only Paillier’s original scheme).In[6]voting was also pointed out as a potential application,however,no suggestion was made there for protocols to prove that an encrypted vote is correctly formed,something that is of course necessary for a secure election in practice.In work done concurrently with and independent from ours,Baudron,Fou-que,Pointcheval,Poupard and Stern[1]propose a voting scheme somewhat similar to ours.Their work can be seen as being complementary to ours in the sense that their proposal is more oriented towards the system architectural aspects of a large scale election,and less towards optimisation of the building blocks.To compare to their scheme,wefirst note that there the modulus length k must be chosen such that k>L log M.The scheme produces ballots of size O(k·L).An estimate with explicit constants is given in[1]in which the dominating term in our notation is9kL.Because our voting scheme uses the generalised Paillier crypto system,k can be chosen freely,and the voting scheme can still accommodate any values of L,M.If we choose k as in[1],i.e.k>L log M,then the ballots we produce have size O(k·log L).Working out the concrete constants involved,onefinds that our complexity is dominated by the term11k log L.So for large scale elections we have gained a significant factor in complexity compared to[1].In[8],Hirt and Sako propose a general method for building receipt-free elec-tion schemes,i.e.protocols where vote-buying or-coercing is not possible because voters cannot prove to others how they voted.Their method can be applied to make a receipt-free version of the scheme from[4].It can also be applied to our scheme,with the same efficiency gain as in the non-receipt free case.3A Generalisation of Paillier’s Probabilistic Encryption SchemeThe public-key crypto-system we describe here uses computations modulo n s+1 where n is an RSA modulus and s is a natural number.It contains Paillier’s scheme[9]as a special case by setting s=1.We start from the observation that if n=pq,p,q odd primes,then Z∗n s+1 as a multiplicative group is a direct product G×H,where G is cyclic of order n s and H is isomorphic to Z∗n,which follows directly from elementary numbertheory.Thus,the factor group¯G=Z∗n s+1/H is also cyclic of order n s.For anarbitrary element a∈Z∗n s+1,we let¯a=aH denote the element represented bya in the factor group¯G.Lemma1.For any s<p,q,the element n+1has order n s in Z∗n s+1. Proof.Consider the integer(1+n)i= i j=0 i j n j.This number is1modulo n s+1for some i if and only if i j=1 i j n j−1is0modulo n s.Clearly,this is the case if i=n s,so it follows that the order of1+n is a divisor in n s,i.e.,itis a number of form pαqβ,whereα,β≤s.Set a=pαqβ,and consider a term a j n j−1in the sum a j=1 a j n j−1.We claim that each such term is divisible by a:this is trivial if j>s,and for j≤s,it follows because j!can then not have p or q as prime factors,and so a must divide a j .Now assume for contradiction that a=pαqβ<n s.Without loss of generality,we can assume that this means α<s.We know that n s divides a j=1 a j n j−1.Dividing both numbers by a, we see that p must divide the number a j=1 a j n j−1/a.However,thefirst term in this sum after division by a is1,and all the rest are divisible by p,so the number is in fact1modulo p,and we have a contradiction.Since the order of H is relatively prime to n s this implies immediately that the elementthe following induction step:In the j’th step we know i j−1.This means that i j=i j−1+k∗n j−1for some0≤k<n.If we use this inL((1+n)i mod n j+1)=(i j+ i j2 n+...+ i j j n j−1)mod n j We can notice that each term i j t+1 n t for j>t>0satisfies that i j t+1 n t= i j−1t+1 n t mod n j.This is because the contributions from k∗n j−1vanish modulo n j after multiplication by n.This means that we get:L((1+n)i mod n j+1)=(i j−1+k∗n j−1+ i j−12 n+...+i j−1j n j−1)mod n jThen we just rewrite that to get what we wantedi j=i j−1+k∗n j−1=i j−1+L((1+n)i mod n j+1)−(i j−1+ i j−12 n+...+ i j−1j n j−1)mod n j=L((1+n)i mod n j+1)−( i j−12 n+...+ i j−1j n j−1)mod n j This equation leads to the following algorithm:i:=0;for s dot1:=L(a mod n j+1);t2:=i;for j doi:=i−1;t2:=t2∗i mod n j;t1:=t1−t2∗n k−1i:=t1;endKey Generation On input the security parameter k,choose an RSA modulusn=pq of length k bits2.Also choose an element g∈Z∗n s+1such thatg=(1+n)j x mod n s+1for a known j relatively prime to n and x∈H.This can be done,e.g.,by choosing j,x at randomfirst and computing g;some alternatives are described later.Letλbe the least common multiple of p−1and q−1.By the Chinese Remainder Theorem,choose d such thatd mod n∈Z∗n and d=0modλ.Any such choice of d will work in thefollowing.In Paillier’s original scheme d=λwas used,which is the smallest possible value.However,when making a threshold variant,other choices are better-we expand on this in the following section.Now the public key is n,g while the secret key is d.encryption The plaintext set is Z n s.Given a plaintext i,choose a randomr∈Z∗n s+1,and let the ciphertext be E(i,r)=g i r n s mod n s+1.decryption Given a ciphertext c,first compute c d mod n s+1.Clearly,if c= E(v,r),we getc d=(g i r n s)d=((1+n)ji x i r n s)d=(1+n)jid mod n s(x i r n s)d modλ=(1+n)jid mod n sNow apply the above algorithm to compute jid mod n s.Applying the same method with c replaced by g clearly produces the value jd mod n s,so this can either be computed on thefly or be saved as part of the secret key.In any case we obtain the cleartext by(jid)·(jd)−1=i mod n s.Clearly,this system is additively homomorphic over Z n s,that is,the product of encryptions of messages i,i′is an encryption of i+i′mod n s.The security of the system is based on the following assumption,introduced by Paillier in[9]the decisional composite residuosity assumption(DCRA): Conjecture1.Let A be any probabilistic polynomial time algorithm,and assume A gets n,x as input.Here n has k bits,and is chosen as described above,and xis either random in Z∗n2or it is a random n’th power in Z∗n2(that is,a randomelement in the subgroup H defined earlier).A outputs a bit b.Let p0(A,k)bethe probability that b=1if x is random in Z∗n2and p1(A,k)the probabilitythat b=1if x is a random n’th power.Then|p0(A,k)−p1(A,k)|is negligible in k.Here,“negligible in k”as usual means smaller than1/f(k)for any polynomial f()and all large enough k.We now discuss the semantic security of CS s.There are several equivalent formulations of semantic security.We will use the following:Definition1.An adversary A against a public-key cryptosystem gets the pub-lic key pk generated from secuity parameter k as input and outputs a mes-sage m.Then A is given an encryption under pk of either m or a messagechosen uniformly in the message space,and outputs a bit.Let p0(A,k),re-spectively p1(A,k)be the probability that A outputs1when given an encryp-tion of m,respectively a random encryption.Define the advantage of A to be Adv(A,k)=|p0(A,k)−p1(A,k)|.The cryptosystem is semantically secure if for any probabilistic polynomial time adversary A,Adv(A,k)is negligible in k.In[9],Paillier showed that semantic security of his cryptosystem(which is the same as our CS1)is equivalent to DCRA.This equivalence holds for any choice of g,and follows easily from the fact that given a ciphertext c that iseither random or encrypts a message i,cg−i mod n2is either random in Z∗n2ora random n’th power.In particular one may choose g=n+1always without degrading security.We do this in the following for simplicity,so that a public key consists only of the modulus n.We now show that in fact security of CS s is equivalent to DCRA:Theorem1.For any s,the cryptosystem CS s is semantically secure if and only if the DCRA assumption is true.Proof.From a ciphertext in CS s,one can obtain a ciphertext in CS1by reducing modulo n2,this implicitly reduces the message modulo n.It is therefore clear that if DCRA fails,then CS s cannot be secure for any s.For the converse,we show by induction on s that security of CS s follows from DCRA.For s=1,this is exact.ly Paillier’s result.So take any s>1and assume that CS t for any t<s is secure.The message space of CS s is Z n s.Thus any message m can be written in n-adic notation as an s-tuple(m s,m s−1,...,m1),where each m i∈Z n and m= s−1i=0m i+1n i.Let D n(m s,...,m1)be the distribution obtained by encrypting the message(m s,...,m1)under public key n.If one or more of the m i are replaced by∗’s,this means that the corresponding position in the message is chosen uniformly in Z n before encrypting.Now,assume for contradiction that CS s is insecure,thus there is an adversary A,such that for infinitely many k,Adv(A,k)≥1/f(k)for some polynomial f(). Take such a k.Without loss of generality,assume we have p0(A,k)−p1(A,k)≥1/f(k).Suppose we make a public key n from security parameter k,show it to A, get a message(m s,...,m1)from A and show A a sample of D n(∗,m s−1,...,m1). Let q(A,k)be the probability that A now outputs1.Of course,we must have(∗)p0(A,k)−q(A,k)≥12f(k)for infinitely many k.In thefirst case in(∗),we can make a successful adversary against CS1,as follows:we get the public key n,show it to A,get(m s,...,m1),and return m s as output.We will get a ciphertext c that either encrypts m s in CS1,or is a randomciphertext,i.e.,a random element from Z∗n2.If we consider c as an element inZ∗n s+1,we know it is an encryption of some plaintext,which must have either m sor a random element in its least significant position.Hence c n s−1mod n s+1is an encryption of(m s,0,...,0)or(∗,0,...,0).We then make a random encryption d of(0,m s−1,...,m1),give c n s−1d mod n s+1to A and return the bit A outputs. Now,if c encrypts m s,we have shown to A a sample of D n(m s,...,m1),and otherwise a sample of D n(∗,m s−1,...,m1).So by assumption on A,this breaks CS1with an advantage of1/2f(k),and so contradicts the induction assumption.In the second case of(∗),we can make an adversary against CS s−1,as fol-lows:we get the public key n,show it to A,and get a message(m s,...,m1).We output(m s−1,...,m1)and get back a ciphertext c that encrypts in CS s−1either (m s−1,...,m1)or something random.If we consider c as a number modulo n s+1, we know that the corresponding plaintext in CS s has either(m s−1,...,m1)or random elements in the least significant s−1positions-and something un-known in the top position.We make a random encryption d of(∗,0,...,0),show cd mod n s+1to A and return the bit A outputs.If c encrypted(m s−1,...,m1), we have shown A a sample from D n(∗,m s−1,....,m1),and otherwise a sample from D n(∗,...,∗).So by asumption on A,this breaks CS s−1with an advantage of1/2f(k)and again contradicts the induction assumption.3.1Adjusting the Block lengthTo facilitate comparison with Paillier’s original system,we have kept the above system description as close as possible to that of Paillier.In particular,the description allows choosing g in a variety of ways.However,as mentioned,we may choose g=n+1always without loosing security,and the public key may then consist only of the modulus n.This means that we can let the receiver decide on s when he encrypts a message.More concretely,the system will work as follows:Key Generation Choose an RSA modulus n=pq.Now the public key is n while the secret key isλ,the least common multiple of(p−1)and(q−1).encryption Given a plaintext i∈Z n s,choose a random r∈Z∗n s+1,and let theciphertext be E(i,r)=(1+n)i r n s mod n s+1.decryption Given a ciphertext c,first compute,by the Chinese Remainder Theorem d,such that d=1mod n s and d=0modλ(note that the length of the ciphertext allows to decide on the right value of s,except with negligible probability).Then compute c d mod n s+1.Clearly,if c=E(i,r),we getc d=((1+n)i r n s)d=(1+n)id mod n s(x i r n s)d modλ=(1+n)i mod n s+1Now apply the above algorithm to compute i mod n s.4Some Building Blocks4.1A Threshold Variant of the SchemeWhat we are after in this section is a way to distribute the secret key to a set of servers,such that any subset of at least t of them can do decryption efficiently,while less than t have no useful information.Of course this must be done withoutdegrading the security of the system.In[10],Shoup proposes an efficient threshold variant of RSA signatures.The main part of this is a protocol that allows a set of servers to collectively andefficiently raise an input number to a secret exponent modulo an RSA modulus n.A little more precisely:on input a,each server returns a share of the result,together with a proof of correctness.Given sufficiently many correct shares,thesecan be efficiently combined to compute a d mod n,where d is the secret exponent.As we explain below it is quite simple to transplant this method to our case,thus allowing the servers to raise an input number to our secret exponent dmodulo n s+1.So we can solve our problem byfirst letting the servers help us compute E(i,r)d mod n s+1.Then if we use g=n+1and choose d such thatd=1mod n s and d=0modλ,the remaining part of the decryption is easy to do without knowledge of d.We warn the reader that this is only secure for the particular choice of d wehave made,for instance,if we had used Paillier’s original choice d=λ,then seeing the value E(i,r)d mod n s+1would allow an adversary to computeλandbreak the system completely.However,in our case,the exponentiation result cansafely be made public,since it contains no trace of the secretλ.A more concrete description:Compared to[10]we still have a secret exponentd,but there is no public exponent e,so we will have to do some things slightly differently.We will assume that there are l decryption servers,and a minimumof k<n/2of these are needed to make a correct decryption.Key generationKey generation starts out as in[10]:wefind2primes p and q,that satisfies p=2p′+1and q=2q′+1,where p′and q′are primes and different from p andq.We set n=pq and m=p′q′.We decide on some s>0,thus the plaintext space will be Z n s.We pick d to satisfy d=0mod m and d=1mod n s.Now wemake the polynomial f(X)= k−1i=0a i X i mod n s m,by picking a i(for0<i<k) as random values from{0,···,n s∗m−1}and a0=d.The secret share of the i’th authority will be s i=f(i)for1≤i≤l and the public key will be n.Forverification of the actions of the decryption servers,we need the followingfixedpublic values:v,generating the cyclic group of squares in Z∗n s+1and for eachdecryption server a verification key v i=v∆s i mod n s+1,where∆=l!. EncryptionTo encrypt a message M,a random r∈Z∗n s+1is picked and the cipher text iscomputed as c=g M r n s mod n s+1.Share decryptionThe i’th authority will compute c i=c2∆s i,where c is the ciphertext.Along with this will be a zero-knowledge proof that log c4(c2i)=log v(v i),which will convince us,that he has indeed raised to his secret exponent s i3Share combiningIf we have the required k(or more)number of shares with a correct proof,we can combine them into the result by taking a subset S of k shares and combine them toc′= i∈S c2λS0,i i mod n s+1whereλS0,i=∆ i′∈S\i−i4In fact the random oracle will be needed only to ensure that the non-interactive proofs of correctness of shares will work.Doing these proofs interactively instead would allow us to dispense with the random oracletext,the decryption protocol outputs the correct plaintext,except with negligible probability.Given an oracle that on input a ciphertext returns the correspond-ing plaintext,the adversary’s view of the decryption protocol can be efficiently simulated with a statistically indistinguishable distribution.The full proof will be included in thefinal version of this paper.Here we only give the basic ideas:correctness of the scheme is immediate assuming that the adversary can contribute bad values for the c i’s with only negligible probability. This,in turn,is ensured by soundness of the zero-knowledge proofs given for each c i.For the simulation,we start from the public key n.Then we can simulate theshares s i1,...,s ik−1of the bad players by choosing them as random numbers inan appropriate interval.Since d isfixed by the choice of n,this means that the shares of uncorrupted players and the polynomial f are nowfixed as well,but are not easy for the simulator to compute.However,if we choose v as a ciphertext with known plaintext m0,we can also compute what v f(0)would be,namely v f(0)=v d mod n s+1=(1+n)m0mod n s+1.Then by doing Lagrange interpolation”in the exponent”as in[10],we can compute correct values of v i=v∆s i for the uncorrupted players.When we get a ciphertext c as input,we ask the oracle for the plaintext m.This allows us to compute c d=(1+n)m mod n s−1.Again this means we can interpolate and compute the contributions c i from the uncorrupted players.Finally,the zero-knowledge property is invoked to simulate the proofs that these c i are correct.4.2Some Auxiliary ProtocolsSuppose a prover P presents a sceptical verifier V with a ciphertext c and claims that it encodes plaintext i.A trivial way to convince V would be to reveal also the random choice r,then V can verify himself that c=E(i,r).However,for use in the following,we need a solution where no extra useful information is revealed.It is easy to see that that this is equivalent to convincing V that cg−i mod n s+1is an n s’th power.So we now propose a protocol for this which is a simple generalisation of the one from[7].We note that this and the following protocols are not zero-knowledge as they stand,only honest verifier zero-knowledge.How-ever,first zero-knowledge protocols for the same problems can be constructed from them using standard methods and secondly,in our applications,we will always be using them in a non-interactive variant based on the Fiat-Shamir heuristic,which means that we cannot obtain zero-knowledge,we can,however, obtain security in the random oracle model.As for soundness,we prove that the protocols satisfy so called special soundness(see[2]),which in particular implies that they satisfy standard knowledge soundness.Protocol for n s’th powersInput:n,uPrivate Input for P:v,such that u=v n s mod n s+11.P chooses r at random mod n s+1and sends a=r n s mod n s+1to V2.V chooses e,a random k bit number,and sends e to P.3.P sends z=rv e mod n s+1to V,and V checks that z n s=au e mod n s+1,and accepts if and only if this is the case.It is now simple to showLemma2.The above protocol is complete,honest verifier zero-knowledge,and satisfies that from any pair of accepting conversations(between V and any prover)of form(a,e,z),(a,e′,z′)with e=e′,one can efficiently compute an n s’th root of u,provided2t is smaller than the smallest prime factor of n. pleteness is obvious from inspection of the protocol.For honest ver-ifier simulation,the simulator chooses a random z∈Z∗n s+1,a random e,setsa=z n s u−e mod n s+1and outputs(a,e,z).This is easily seen to be a perfect simulation.For the last claim,observe that since the conversations are accepting,we have z n s=au e mod n s+1and z′n s=au e′mod n s+1,so we get(z/z′)n s=u e−e′mod n s+1Since e−e′is prime to n by the assumption on2t,chooseα,βsuch thatαn s+β(e−e′)=1.Then let v=uα(z/z′)βmod n s+1.We then getv n s=uαn s(z/z′)n sβ=uαn s uβ(e−e′)=u mod n s+1so that v is indeed the desired n s’th root of uIn our application of this protocol,the modulus n will be chosen by a trusted party,or by a multi-party computation such that n has two prime factors of roughly the same size.Hence,if k is the bit length of n,we can set t=k/2and be assured that a cheating prover can make the verifier accept with probability ≤2−t.The lemma immediately implies,using the techniques from[2],that we can build an efficient proof that an encryption contains one of two given values, without revealing which one it is:given the encryption C and the two candi-date plaintexts i1,i2,prover and verifier compute u1=C/g i1mod n s+1,u2= C/g i2mod n s+1,and the prover shows that either u1or u2is an n s’th power. This can be done using the following protocol,where we assume without loss of generality that the prover knows an n s’th root u1,and where M denotes the honest-verifier simulator for the n s-power protocol above:Protocol1-out-of-2n s’th powerInput:n,u1,u2Private Input for P:v1,such that u1=v n s1mod n s+11.P chooses r1at random mod n s+1.He invokes M on input n,u2to get aconversation a2,e2,z2.He sends a1=r n s1mod n s+1,a2to V2.V chooses s,a random t bit number,and sends s to P.3.P computes e1=s−e2mod2t and z1=r1v e11mod n s+1.He then sendse1,z1,e2,z2to V.4.V checks that s=e1+e2mod2t,z n s1=a1u e11mod n s+1and z n s2=a2u e22mod n s+1,and accepts if and only if this is the case.The proof techniques from[2]and Lemma2immediately implyLemma3.Protocol1-out-of-2n s’th power is complete,honest verifier zero-knowledge,and satisfies that from any pair of accepting conversations(between V and any prover)of form(a1,a2,s,e1,z1,e2,z2),(a1,a2,s′,e′1,z′1,e′2,z′2)with s=s′,one can efficiently compute an n s’th root of u1,and an n s’th root of u2, provided2t is less than the smallest prime factor of n.Ourfinal building block allows a prover to convince a verifier that three encryptions contain values a,b and c such that ab=c mod n s.For this,we propose a protocol inspired by a similar construction found in[3].Protocol Multiplication-mod-n sInput:n,g,e a,e b,e cPrivate Input for P:a,b,c,r a,r b,r c such that ab=c mod n and e a=E(a,r a),e b=E(b,r b),e c=E(c,r c)1.P chooses a random value d∈Z n s and sends to V encryptions e d=E(d,r d),e db=E(db,r db).2.V chooses e,a random t-bit number,and sends it to P.3.P opens the encryption e e a e d=E(ea+d,r e a r d mod n s+1)by sending f=ea+d mod n s and z1=r e a r d mod n s+1.Finally,P opens the encryptione f b (e db e e c)−1=E(0,r fb(r db r e c)−1mod n s+1)by sending z2=r fb(r db r e c)−1modn s+1.4.V verifies that the openings of encryptions in the previous step were correct,and accepts if and only if this was the case.Lemma4.Protocol Multiplication-mod-n s is complete,honest verifier zero-knowledge,and satisfies that from any pair of accepting conversations(between V and any prover)of form(e d,e db,e,f,z1,z2),(e d,e db,e′,f′,z′1,z′2)with e=e′, one can efficiently compute the plaintext a,b,c corresponding to e a,e b,e c such that ab=c mod n s,provided2t is smaller than the smallest prime factor in n. pleteness is clear by inspection of the protocol.For honest verifier zero-knowledge,observe that the equations checked by V are e e a e d=E(f,z1)mod n s+1and e fb (e db e e c)−1=E(0,z2)mod n s+1.From this it is clear that wecan generate a conversation by choosingfirst f,z1,z2,e at random,and then computing e d,e db that will satisfy the equations.This only requires inversion modulo n s+1,and generates the right distribution because the values f,z1,z2,e are also independent and random in the real conversation.For the last claim, notefirst that since encryptions uniquely determine plaintexts,there arefixed values a,b,c,d contained in e a,e b,e c,e d,and a value x contained in e db.The。

Unit 6:Death and JusticeHow Capital Punishment Affirms LifeBy Edward I. Koch死亡与司法死刑如何肯定生命Edward I. Kochst December a man named Robert Lee Willie, who had been convicted of raping and murdering an eighteen-year-old woman, was executed in the Louisiana state prison. In a statement issued several minutes before his death, Mr. Willie said: “Killing people is wrong… It makes no difference whether it’s citizens, countries, or governments. Killing is wrong.” Two weeks later in South Carolina, an admitt ed killer named Joseph Carl Shaw was put to death for murdering two teenagers. In an appeal to the governor for clemency, Mr. Shaw wrote: “Killing was wrong when I did it. Killing was wrong when you do it. I hope you have the courage and moral strength to stop the killing.”去年12月,一个名叫罗伯特.李.威利的罪犯在路易斯安那州的监狱中被处决,罪名是强奸和谋杀一名18岁的女子。

Geographic features and its total area.:Britain is situated in Western Europe and is separated from the European continent in the east by the North Sea, the Strait of Dover and the English Channel in the south. It is an insular(保守的)country. Its coastline runs 12,429 km, It is one of the countries with longest coastline. To thewest of it lies the Atlantic Ocean, across and beyond it is America. The Straits of Dover between France and England is quite narrow and itis 33 km across. In 1985 the British government and the French government decided to build a channel tunnel under the Straits of Dover so that England and France could be joined together by road. Thischannel tunnel was opened to traffic in May 1994 after eight years hard work.The Britain faces Scandinavia Peninsular (Norway, Sweden and Denmark) to the northeast and to the North lies Iceland To the south across the English Channel lies France and Belgium and to the east across North Sea lie Germany and Holland.The total area is about 244,820 square kilometers.It Is over 1,000 km. from south to north and it is about 500 km.from west to east.2. The names of UKIts full name is the United Kingdom of Great Britain and Northern Ireland, usuallyshortened , abbreviated to the United Kingdom or U.K.. It may also called Great Britain, Britain or informally England.England: 130.000skm, 60% of whole island.British Isles: Two large islands and several small onesBritain:The United Kingdom of Great Britain and Northern Ireland.Great Britain :England, Wales, ScotlandBritain is divided into highland area and lowland area.It has large mountain ranges : the Pennies :Bulk of Pennines(奔宁山脉) is moorland.The Cumbrian Mountain Range, the Grampian Mountains , the Cambrian Mountain Range and such important rivers as Thames River ,the Seven River, Mercy River, the Humber, the Clyde River and the Forth.Scotland has an area of 78,760 square kilometers in northern part.It is situated in the north of Great Britain with a good number of mountains and islands. There are 800 islands which contain Hebrides, Shetland and Orkney islands. Edinburgh is the capital of Scotland.Wales: Wales is in the west of Great Britain. It has an area of20,761 square kilometers and it take up less than 9% of the whole island. The capital of Wales is Cardiff. Most of Wales is mountainous. The hills rise steeply from the sea and rather flat on top. 6% of Wales is covered with forest and much of the country is pastureland for sheep and cattle. Wales on the WesternProminence. 20.700skm, 9% of the whole island.Wales was united to England in 14th centuryNorthern Ireland takes up the northern fifth of Ireland. It has an area of 14,147 square kilometers. It is made up of six counties that consist of fertile, drumlin [`dr?mlin] (鼓丘) countrysurrounding Lough Neagh. Belfast is the capital of Northern Ireland. Mountains in the north4and south, separated by the fertile basin of Lough Neagh, mainly agricultural, industrial center: two ports– Belfast and Londonderry.3. Climate and Weather ------A maritime type of climate:1) moderated by the Atlantic Gulf Stream, milder than places in the same latitude. 2) equable: winters are mild, temperature exceed 4c inthe west, lower in the east. July about 18c. 13c in the northern Scotland.3) changeable day-t-day conditions.4) Rainfall throughout the year. No marked dry season.In Britain the weather is rainy, changeable and unpredictable. In fact it has a favorable maritime climate. It rarely rises above 32? in summer or falls below –10? in winter. Wintersare mild, not too cold and summers are cool, not too hot.― Can I compare thee to the summer‘s day ?‖Rainfall: Britain has a steady reliable rainfall throughout the whole year. The average annual rainfall in Britain is over 1,ooo mm.It is rainy and so changeable and unpredictable. One can experience four seasons in the course of a single day. Britain is famous for its fogs. The smoke-fogs of the big town, which used to develop in winter time whenever there was not enough wind to blow the smoke away, were horrible, unhealthy and dangerous to movement4. Rivers and lakes and natural resourcesThere are many lakes and rivers in England: but not very large.1) the longest river: Severn River, 355km2) Thames River, 338km, in Oxford3) Clyde River in Scotland4) lakes lies in Northern Scotland & the Cambria Mountains and North Wales England is rich in coal, iron, tin, copper, oil and gasThere are no large land-based oilfields except in North Sea.

( + )Lecture Two The People(1)Question for discussion:1) What are the Celtic languages? Are they still alive?2) How has English language evolved in history? Is it important tothe UK‘s class structure?3) What are the minor languages spoken in the UK,Overview: Population: 56,500,000English 80%; Welsh 5%; Scots 10%; Irish 4%.1. The English: Anglo-Saxon in origin, Germanic tribes conquered in the 5th, 6th AD. Norman French, Under William of Normandy in 1066. Welsh, Scot, Irish: Celts from north-western Europe, invaded Britain between700BC and 200BC.1.1 The characteristics of English people: reserved, unemotional, courteous; shy of strangers; suspicious of change and slow to accept new ideals; solid and dependable with a high sense of honesty, duty and justice; physically and morally courageous; conscious of his place inthe social order, disliking any show of emotion and lack of control.2. The Welsh is composed of two groups of people:1) sheep farmers in the mountainous regions of the centre and north;2) industrial workers in the south2.1 Characteristics of Welsh people: musical, emotional, cheerful, proud of their past, and welcoming to friends but suspicious of foreigners. They lived hard-working lives of the Welsh The culturalpride in Wales is very strong, famous for their love of music and poetry. Welsh is an ancient Celtic language, more different from English than English is from French or German.3. Characteristics of the Scots: inventive, hard-working, serious-minded and cautious withmoneyA) Highlanders live by farming sheep and fishing, being proud, independent, hardy B) Lowlanders live in industrialized urban areas.2) Great empire builders, fierce soldiers . ―Devils in skirts‖ or―ladies from hell‖ are nicknames ofScottish soldiers for their bravery.3) Distinctive national dress: kilt, pleated skirts( 百折裙)4.Characteristics of Irish: introspective(好反省的) dreamers and poets, argumentative and6aggressive.1) IRA: the Irish Republican Army on the Catholic side. 2) Ulster Unionists, (Loyalists) on the Protestant side.5 .

Roman Britain (55BC –410)1) Julius Caesar came to Britain in 55BC.2) Roman occupation lasted about 400 years.6.3 Impacts on its culture1) brought Christianity to England2) built roads all across Britain3) towns grew up along the Roman roads4) English upper classes became completely Romanized, Roman landowners and officials.5) Social systems: laws, taxes6) Roman language---Latin7) system of writing & numbering8) written description of the land, peoples9) engineering skills, architecture7. Anglo-Saxon times (446-871)Three Germanic tribes invaded England: Angles, Saxons and Jutes. The name England is namedafter Angles.7.1. Danish InvasionAt the turn of 8th century, Danes, or Vikings, invaded England from Norway & Denmark.8. NormansThe Norman Conquest in 1066.78.1 Consequences: William of Normandy and his French-speaking followers set up a strong central government which brought a new unified discipline and control to England. 8.2.

Germanic (d)th2) By the late 7 century, _____ Christianity became the dominant religion in England.A. CelticB. Anglo-SaxonC. GermanicD. Roman (d)Part I Politics Feudal EnglandRecorded history in Britain began in the year 55BC, when Julius Caesar and his Roman troopsththinvaded the island. Between the 8 and 5 centuries BC, the Celts inhabited the island and becamethe dominant residents. The name Britain came from the Britons, a Celtic tribe. In 43AD, Britainthsubsequently became a Roman province and it remains so until the beginning of the 5 century.Many of the native Celtic were driven to the mountainous region of Scotland and Wales, which remain unconquered by the Romans. The Roanswere excellent builders and they constructed towns and cities which prospered far longer than any previous settlements on the island. In 410, Germanic barbarians attacked Roman, forcing all Roman troops to leave Britain, which ended the Roman occupation of the island. These warriors included the Angles, the Saxons and Hutes. From that time on, English, the language of the Angles, replaced the old Celtic language as the dominant language of the land. As the Anglo-Saxon were not Roman Christian, St. Augustine was sent to Britain to convert the Anglo Saxon people in 587 with 40 missionaries. They converted many Anglo-Saxons to Roman Christians. Augustine founded a church and a monastery in Canterburythand became the first Archbishop of Canterbury in 601. By the late7 century Roman Christianitythbecame the dominant religion in Britain. In the 8 century the Vikings from the Scandinaviancountries of Northern Europe to attack the English coast. The seven Anglo-Saxons= kingdom in England gradually united under Alfred the Great. In 1042, Edward the Confessor,, as a piousChristian, built Westminster Abbey, which exists today. On September 28, 1066, William crossed the channel with a formidable army. His army defeated the English army King Harold (brother in law of Edward) at the battle of Hastings. and began the Norman Conquest of England, which marked the establishment of feudalism in England.By the year 1154, Henry II, William‘s great grandso n, ascended the throne and thus began therule of the House of Anjou(also known as (the House of Plantagenet). Henry II is best remembered for his reform of the courts and the laws, He improved the courts of justice,8introduced the jury system and institutionalized common law. After Richard I, son of Henry II, was killed in France, his brother John ascended the throne in 1199. He was defeated in a war in France and lost Normandy in 1204. Dissatisfied with John‘s leadership, the lords forced him tosign the Magna Carta(大宪法), which is regarded as the foundation of the Britishconstitutionalism and it provides the basic principles for the protection of individual rights. P15 The Hundred Years War (1337-1453) was a series of wars between England and France over trade, territory, security and the throne. This war had significant impact on the English society. It promoted the English concept of nationalism and promoted the development of the textile industry.The War of the Roses was a series of Civil War between two great noble families: the House of York, whose badge was a white rose, and the House of Lancaster, whose badge was a red rose. Both houses battled for power, wealth and ultimately the throne. in the end , the House of Lancaster won and their leader Henry Tudor became King Henry VII andstarted the rule of the House of Tudor, an efficient centralized government.1. Under William’s rule, the Normans changed England to a feudal state under an absolute kingship.2. King Arthur: in 6th, the central figure of many legends about him and his Knights of round Table.3. the Magna Carta– Great Charter, a document signed in 1215 byKing John, to recognize the rights of barons.4. Hundred Years’ War: between England & France from 1337 to 1453in France. French drove English partly through the inspiration of Joan of Arc (a French saint & national heroine), partly through the effective use of guns.5. Wars of the Roses: struggle for the throne of England (1455-1485)between . The houses of Lancaster, whose badge was a red rose, and York, a white rose. Impacts: the war weakened both nobility and the monarch.6. The Black Death: a deadly bubonic plague(淋巴腺鼠疫), struck Europe in middle of 14th,reached England in 1348. ? of the population died.7. Religious Revolution1) the Catholic Church:A) headed by the Pope;B) members accept the gospel of Christ and the teachings of the Bible.C) Any revolt against the traditional Christian faith was “heresy”.D) in the Middle Ages, Pope was powerful2) Protestant Church:A) whose faith and practice originated with the principles of the Reformation. B) Pope’s political power and religious authority declinedin 16th, Protestant churches sprang up in Northern Europe, and in the Elizabethan age, became gradually the do minant faith. 3) Henry VIII’s divorce question, married his brother’s widow, a Spanish princess, who gave adaughter, Mary, not a son.4) Bloody Mary: a devout Catholic, burnt so many protestants; succeeded by Elizabeth I. 5) Elizabethan age: literary achievement, Shakespeare, an age of adventure on the sea.There was an inevitable conflict between the Roman Catholic Churchand the King of9England who had established absolute monarchy. At that time , theonly person who could grant a divorce was the Pope. So Henry VII started the Reformation movement by declaring a break with Rome. He carried outa wholesale suppression of the monasteries and declared himself to bethe ―only supreme head of the church( in his Act of Supremacy in 1534). The Reformation was in essence a political movement in a religious guise.Part II The English Civil War1. a bitter power struggle (1642-1648) between the monarchy and Parliament.2. the victory of the Parliament led to the execution of Charles I in 1649, and the temporary overthrow of the monarchy.3. a republic founded by Oliver Cromwell for more than ten years.4. King Charles I: divine rights to govern,Ruled without parliament, levied taxes without parliament’s approval.5. Cromwell: Roundhead leader, defeated the King Charles I.The Glorious Revolution1. in 1688, Catholic king James II fled to France.2. the throne was offered to his Protestant daughter and her husband Dutch king William.3. the Bill of Rights was passed by Parliament to restrict the power of the Monarchy.4. beginning of the Constitutional Monarchy in Britain.5. Since then every English monarch rules by permission of Parliament.6. the theories of divine or hereditary right to the throne were ended.7. Bloodless Revolution7.Background:7.1. The 18th century saw ascendancy of the middle class in the life of the nation, with the development of commerce & industry.7.2. Glorious Revolution established the authority of middle class over the crown. 7.3. The union of Scotland and England into the nation of Great Britain --- the Act of Union of 1707.7.4. The Seven Years’ War (1756-63) in North America (French and India War) --- which left Britain predominant in North America and in India, Britain became the world’s leading colonialpower.7.5. In the 2nd half of the 18th century, the great economic and social changes were taking place in Britain --- agricultural and home-based trades and industries gradually gave way to factory-based industries with complex machinery.7.6. England was a great trade nation, with much private capital ready for investment. Not only was trade free to move throughout the British Isles, but also there was freedom of movement between the social classes. Middle class values encouraged self-reliance and enterprising initiative.7.8. Political leaders were interested in commerce. The growing population provided a market. Farmers‘ improved methods of cultivation freed much labor, which became available for employment in the town factories, and also increased food supplies for towns. 7.9 18th century was a time of peace and stability.

Mercantilism was the basic policy imposed by Britain on its colonies. Mercantilism meant that the government and the merchants became partners with the goal of increasing political power and private wealth, to the exclusion of other empires. The government protected its merchants—and kept others out—by trade barriers, regulations, and subsidies to domestic industries in order to maximize exports from and minimize imports to the realm. The government had to fight smuggling—which became a favorite American technique in the 18th century to circumvent the restrictions on trading with the French, Spanish or Dutch.5. The BBC was founded in 1926 as a public service radio station and later moved into television. It's now Britain's main public service broadcaster. It currently has two TV channels. BBC 1 specializes in shows with a broad appeal. BBC 2 supplies people with documentaries and shows aimed at particular social groups. The BBC also provides the World Service which broadcasts in English and 43 other languages throughout the world.6. Britain used to rule a third of the globe and thus became a great empire in the world. After the Second World War, the British Empire began to decline as more and more former colonies declared their political independence. Throughout the next few decades, the process of decolonization continued, though sometimes the process was full of violence. The end of the great British Empire was inevitable. Today the age of。

5_The_One_Against_the_Many

Lesson Five The One Against the ManyArthur M. Schlesinger Jr.●ObjectivesAfter studying this essay, students will be able to:1. grasp the main idea of the argumentation (A society should allow free flow of manyviewpoints in order to develop itself.);2. relate what is discussed in the essay to Chinese experience and the current worldsituation so as to better understand the points (the great setback we suffered by sticking to dogmatism in the past, our principles of non-interference and peaceful co-existence in dealing with international affairs );3. get themselves familiar with some key philosophical terms such as pragmatism,dogmatism, absolutism, dialectics, rationalism, determinism, empiricism, ideal, ideology, etc.;4. grasp the major techniques employed in developing the argument (contrast, citingexamples, clear organization of ideas, etc.)5. conduct a series of reading, listening, speaking and writing activities related to thetheme of the unit.●About the titleWhen you first see this title, you might wonder what it is about. What is the one and what is the many? Is it about a war between two parties who vary greatly in number? That is to say, the title is very attractive. It draws readers‘ attention and interest at the first glance. That is one of the many skills you should learn. When you write an article, it is important to give it a good title. A good beginning means half success.●General StructureThe whole text include as many as 7 parts.Part I is the opening paragraph. In this one-sentence paragraph, the author, right to the point, raise the issue of American experience in achieving rapid national development.Part II (Paras.2-6). In this part, the author lists all those Factors that facilitated the rapid social and economic development of the United StatesWhat is the fundamental factor according to the author? Could you find the original sentence from the text? (para.6) ---- ―But fundamental to all of these… has been the national rejection of dogmatic preconceptions about the nature of the social and economic order.Part III (P aras.7 -10) Ideology and Pragmatism and American’s Attitude towards ThemHere, the author defines the term ―ideology‖and points out that though not always immune to the temptation of ideology, Americans have been skeptical about ideology and have accepted pragmatism in most of the time in American history. The American Revolution is used as an example to illustrate the difference between pragmatism and ideology.Part IV (Paras.11-12) Ideals and IdeologyIn this part, the author uses Thomas Jefferson as an example to illustrate thedistinction between ideals and ideology.Part V (Paras.13-14) What is wrong with faith in Ideology?In answering this question, the author points out that the ideologists confuse ideology, an abstraction from reality, with reality itself. This confusion leads to two bad results, in the interpretation of history and the choice of public policy.Part VI (Paras.15-19) Differences between the Ideologist and PragmatistFrom two aspects, the author further illustrates (elaborates on) the difference between the ideologist and the pragmatist, that is, how they differ in their views of history and their approaches to issues of public policy.Part VII (Paras.20-22) Conclusion: the Many should be the ChoiceIn this concluding part, the author sums up the conflict of our time (i.e. the conflict between ideologists and pragmatists). He analyses the goal of ideologists and the goal of free men, leading to the conclusion that the many should be the choice.Detailed study of the text bodyPara.11.In an epoch dominated by the aspirations of new states for nationaldevelopment…●period, epoch, era and agePeriod is the general term for any portion of historical timeEpoch and era are often used interchangeable, but in strict discrimination, epoch applies to the beginning of a new period marked by radical changes, new development, etc. and era, to the entire period.e.g.: The founding of new China marked a new epoch in Chinese history.The 20th century was an era of technological revolution.Age is applied to a long period identified with some dominant personality or distinctive characteristic.e. g. the Stone Age, the Middle Ages; the Victorian Age●From this statement, could you guess when this essay was written?If you know world history well enough, you may know that the essay was probably written in the late 1960s or early 1970s when many countries in Asia and Africa won their independence and wanted to develop their countries. You can see that the author is keen to international situation, which makes his essay worth of reading. In fact, the author‘s viewpoints are still of great value to us today since we are seeking for a rapid national development.Part II (Paras.2-6)Para.22.Every country, of course, has its distinctive development problems…●What role does this sentence play?---- It is a transitional sentence.●Is it true to say so? --- Absolutely right. The development problems andsolutions vary from country to country. Usually one can draw insights from those useful experiences of other countries but to try to copy use one model for different problems and situations is to invite disaster. In our history, we tried to copy the model of former soviet unions. Was it successful? Of course not. This is the best example●Capacity: ability to do things.3.The country was blessed by notable advantages….Bless: to favorBe blessed with: to be favored with, be fortunate enough to possess e.g. I am not rich but am blessed with good health.4.Had that been so, the Indians, for whom ….●―.. would have developed‖: subjunctive mood●had that been so…: if that had been so. If the favorable ratio betweenpopulation and resources had been the only factor…●―first settlers‖refers to the founders of Jamestown in 1607 and the 102passengers who sailed on the Mayflower in 1620 to plant the first colony atPlymouth (in what is today southeastern Massachusetts)5.What mattered equally was the spirit….●approach: to begin dealing with; to adopt a method for attaining a goal orpurpose●What can the challenges be?The challenges may include the diseases, hunger and harsh environment they faced after their landing in the New World, their relationship with the native Indians. (We have talked a lot about those challenges faced by frontiers in lesson2. what the first settlers had to deal with is quite the same with that those frontiersdid.)Para.36.One factor was the deep faith in education…..●Faith: complete, unquestioning acceptance of something●Why does the author say this belief existed from the earliest days ….?The first settlers were mainly puritans who had a tradition of respecting learning because they believed that reading the Bible is the only way to communicate with God. Therefore, after they settled down and solved the problem of feeding their family, the next thing they did was to build churches and schools in their settlement. For instance, The Harvard College was founded in 1636, the Yale College in 1701. A public school system was set up in Massachusetts in 1647.7.It arose originally from a philosophical rather than an economic commitment….●philosophical commitment: dedication to abstract thought-out principles. Here,it refers to dedication to the belief and values of democracy.●It arose originally from a philosophical rather than economic commitment…The thinking of Thomas Jefferson exemplifies the position that State-owned education for all citizens was seen as a basic requirement for democracy. He wrote in 1816,―If a nation expects to be ignora nt and free, in a state of civilization, it expects what never was and never will be.‖Education was seen as the means to enable the public to make ―right choices‖.( those consistent with democratic values) and maintain stability within the republic.The United State has a number of laws on education:The Morrill Land Grant Act of 1862The G.I. Bill of 1944National Defense Education Act of 1958The Elementary and Secondary Education Act of 1965The Higher Education Act of 1965Now, the United States has the most advanced educational system in the world which offer unparalleled educational opportunity to its youth. For instance,between 1990 and 1995 over 8.5 million students enrolled every year in colleges and universities. Remember, the total population of the United States is about 2 billion.( how many enrolled in our country?)●But, at the same time, it also helped produce the conditions essential tosuccessful …In spite of the fact that economic commitment was not the major reason for respect for learning, wide literacy became a necessary condition for modernization. Just as the saying goes ―Knowledge is power‖. Max Weber points out that Protestant ethics paved the way for the development of capitalism.This statement also serves as a smooth transition to the next paragraph.Para.48.Modern industrial society must be above all a literate society.●This sentence echoes with the last sentence of the previous paragraph andforms a smooth transition. In writing your own essays, you should learn to use transitional sentences to ensure a smooth running of ideas.●Do you think the concept applicable to China, too?Does it remind you of Our national policy of ―科教兴国‖? It is based on this concept.9.J.K. Galbraith has rightly observed that….●intellectual improvement: increase in one‘s intellectual ability, referring toeducation智力提高●capital goods: materials used in production生产资料●report: to recount, to give an account of●Galbraith‘s observation is correct, but it takes decision-makers with long-termperspective to really grasp the significance of Galbraith‘s observation and to do accordingly. Why? Because money invested in construction may bring tangible results in a relatively short period of time while the result of investment in intellectual improvement may not be evident/ obvious for a long period of time.As soon as China decided to shits its priority to national construction, one of the first things done was to reintroduce national college entrance examination in 1977. For the same reason, we have made education, science and technology a major means in our social and economic development. However, in many places, education is still neglected by local officials. Actually, we are not unfamiliar with reports about improper usage of educational investment and postponed payment of school teachers. So, it is still a hard task to make decision-makers at all levels to really grasp Galbraith‘s observation.Para.510.Another factor in the process of American development has been the commitmentto ….●Self-government is the principle that the people are the ultimate source ofgoverning authority and that their general welfare is the only legitimate purpose of government. Do you know the address by Abraham Lincoln at Gettysburg with the world famous saying ―…a government of the people, by the people and for the people‖? This saying represents the essence of self-government. I must say, this is a political ideal sought after by all nations including us. We have similar slogans such as ―nothing is trivial when itconcerns the interests of the people‖, ―to govern for the people‖and ―to represent the greatest interests of the largest number of people‖, etc.Three Represents:the CPC has always represented the development trend of advanced productive f orces,the orientation of advanced culture and the fundamental interests of the overwhelming majority of the people in China.●Representative institutions: refer to a system of government institutions thatgive citizens the opportunity to vote for representatives who will work ontheir behalf. In the United States, every four years, the voters will vote formembers of the electoral college who will, in turn, elect the president. Everytwo years, the voters will elect members of the House of Representatives.and one third of the members of the Sen ate. It is anybody‘s guess whether these people, once elected, will work for the interests of the majority of the people.In the presidential election of 2000, about half of the qualified voters tookpart in the vote, of which, half voted for George W. Bush.

草率概括的谬误英语作文

草率概括的谬误英语作文

草率概括的谬误英语作文Title: The Pitfalls of Hasty Generalization。

Hasty generalization, a common fallacy in reasoning, occurs when one draws a conclusion based on insufficient evidence or a limited sample size. This error in thinking can lead to misconceptions, stereotypes, and flawed judgments. In this essay, we will explore the implicationsof hasty generalization, its prevalence in various contexts, and strategies to mitigate its impact.First and foremost, hasty generalization undermines the credibility of arguments and decisions. By extrapolating from a small or unrepresentative sample, individuals risk overlooking important nuances and complexities within a given situation. For example, forming opinions about an entire demographic based on the actions of a fewindividuals perpetuates stereotypes and fosters discrimination.Moreover, hasty generalization distorts reality and impedes critical thinking. In the age of information overload, people are often inundated with anecdotes, opinions, and cherry-picked data points. Without careful scrutiny and analysis, these snippets of information can shape erroneous beliefs and misguided perceptions. Consequently, individuals may overlook contradictory evidence or alternative viewpoints, leading to a narrow-minded outlook on issues.The ramifications of hasty generalization extend beyond individual cognition to societal structures and public discourse. In politics, for instance, politicians may exploit this fallacy to sway public opinion and garner support for their agendas. By selectively highlighting isolated incidents or cherry-picking statistics, they manipulate emotions and perceptions to advance their narratives. As a result, constructive dialogue and evidence-based policymaking are sidelined in favor of polarizing rhetoric and partisan agendas.In addition, hasty generalization permeates the realmof media and popular culture. Sensationalized news headlines, clickbait articles, and viral social media posts often rely on exaggerated anecdotes or cherry-picked examples to attract attention and generate engagement. This sensationalism not only distorts reality but also perpetuates misinformation and reinforces existing biases among the audience.To counteract the pitfalls of hasty generalization, it is imperative to adopt a critical mindset and employ evidence-based reasoning. This entails questioning assumptions, seeking diverse perspectives, and rigorously evaluating the validity of sources. By cultivating a habit of skepticism and intellectual humility, individuals can guard against the allure of simplistic narratives and superficial conclusions.Furthermore, promoting media literacy and critical thinking skills is essential in combating the spread of hasty generalization. Educating individuals on logical fallacies, research methodologies, and fact-checking techniques empowers them to navigate the informationlandscape discerningly. By fostering a culture of intellectual rigor and skepticism, society can inoculate itself against the pernicious influence of hasty generalization.In conclusion, hasty generalization poses a significant threat to rational discourse, informed decision-making, and societal cohesion. By succumbing to this fallacy, individuals risk oversimplifying complex issues, perpetuating stereotypes, and undermining the pursuit of truth. Through introspection, education, and critical thinking, we can guard against the allure of hasty generalization and cultivate a more reasoned and equitable society.。

行政管理理论英文

行政管理理论英文

行政管理理论英文Public Administration TheoryIntroductionPublic administration is an important field of study that focuses on the implementation and management of government policies and programs. It encompasses various theories and approaches that aim to improve the efficiency and effectiveness of public sector organizations. In this paper, we will explore several key theories in public administration, including classical, behavioral, systems, and contingency theories. We will also examine the evolution of public administration theory and its relevance in today's complex and rapidly changing world.Classical TheoryClassical theory is one of the earliest and most influential approaches to public administration. It is based on the idea that organizations should be structured and managed in a rational and hierarchical manner. This theory was developed during the late19th and early 20th centuries, when industrialization and urbanization led to the need for more efficient and effective forms of governance.One of the key figures in classical theory is Max Weber, who proposed the concept of bureaucracy as a way to organize and manage complex organizations. Weber identified several key principles of bureaucracy, including division of labor, hierarchy of authority, rules and regulations, impersonality, and career advancement based on merit. These principles are intended to create a rational and efficient organizational structure that caneffectively carry out the goals and objectives of the government. Behavioral TheoryBehavioral theory emerged as a reaction to the shortcomings of classical theory, particularly its emphasis on formal structure and rational decision-making. Behavioral theorists argued that human behavior is complex and often irrational, and that organizations should be designed and managed with this in mind. This approach focuses on the psychological and sociological aspects of organizational behavior, with an emphasis on employee motivation, leadership, and group dynamics.One of the key figures in behavioral theory is Chester Barnard, who proposed the concept of the "acceptance theory of authority." According to Barnard, authority is only effective if it is acceptedby the subordinates, and managers must take into account the needs and motivations of their employees in order to achieve organizational goals. This perspective led to a greater emphasis on human relations and employee participation in decision-making, as well as a recognition of the importance of informal networks and communication within organizations.Systems TheorySystems theory is based on the idea that organizations are complex and interdependent systems that must be understood as a whole, rather than as a collection of separate parts. This approach emphasizes the interconnectedness of different elements within an organization, as well as the interactions between the organization and its external environment. Systems theory also highlights the importance of feedback loops and the ability of organizations toadapt and evolve in response to changing conditions.One of the key figures in systems theory is Ludwig von Bertalanffy, who developed the concept of "general systems theory." According to von Bertalanffy, general systems theory provides a framework for understanding the common principles that underlie all complex systems, regardless of their specific nature or domain. This approach has been influential in shaping our understanding of organizations as open, dynamic, and adaptive systems that are constantly interacting with their environment. Contingency TheoryContingency theory is based on the idea that there is no one-size-fits-all approach to management, and that the best course of action depends on the specific context and circumstances facing an organization. This approach emphasizes the need for managers to be flexible and adaptable in their decision-making, and to take into account the unique challenges and opportunities presented by different situations.One of the key figures in contingency theory is Fred Fiedler, who developed the "contingency model of leadership." According to Fiedler, the effectiveness of a leader depends on the match between their leadership style and the situational context in which they are operating. This perspective has led to a greater recognition of the importance of situational awareness and the need for managers to be able to adjust their approach in response to changing conditions.Evolution of Public Administration TheoryOver the years, public administration theory has evolved in response to changes in the external environment, as well as advances in organizational and management scholarship. One important trend has been the shift from a focus on formal structure and rational decision-making to a greater emphasis on organizational behavior and the complex, dynamic nature of organizations. This has led to a greater recognition of the importance of human relations, employee motivation, and the need for organizations to be able to adapt and evolve in response to changing conditions.Another important trend has been the increasing recognition of the importance of the external environment in shaping the behavior and performance of organizations. This has led to a greater emphasis on the interconnectedness of organizations and the need for them to be able to respond to changes in their external environment in order to remain effective. This has also led to a greater recognition of the importance of collaboration and networked governance in addressing complex and interdependent public policy challenges.Relevance in Today's WorldPublic administration theory remains highly relevant in today's complex and rapidly changing world. Organizations are facing unprecedented challenges and opportunities as a result of globalization, technological innovation, and demographic change. In this context, the principles and insights provided by public administration theory can help organizations to navigate these challenges and to remain effective and responsive in the face of uncertainty and complexity.One important area of relevance is in the realm of public policy and governance. Public administration theory provides valuable insights into the management of public sector organizations, as well as the design and implementation of public policies and programs. This can help to ensure that public sector organizations are able to effectively carry out their mandates and to deliver high-quality services to the public in a cost-effective and accountable manner.Another important area of relevance is in the realm of organizational behavior and management. Public administration theory can help to illuminate the complex and dynamic nature of organizations, as well as the challenges and opportunities facing managers and leaders. This can help to ensure that organizations are able to adapt and evolve in response to changing conditions, as well as to foster a more inclusive, collaborative, and effective work environment.ConclusionIn conclusion, public administration theory encompasses a diverse range of perspectives and approaches that aim to improve the efficiency and effectiveness of public sector organizations. Classical, behavioral, systems, and contingency theories each provide valuable insights into the management and governance of organizations, as well as the challenges and opportunities facing them. The evolution of public administration theory has led to a greater emphasis on the dynamic and interconnected nature of organizations, as well as the importance of collaboration and adaptability in responding to changing conditions. In today'scomplex and rapidly changing world, public administration theory remains highly relevant and can provide valuable guidance for organizations and policymakers as they navigate the challenges and opportunities of the 21st century.。

武汉大学考博英语模拟试卷26(题后含答案及解析)题型有:1. Reading Comprehension 2. English-Chinese Translation 3. Chinese-English Translation 4. WritingReading ComprehensionFriction between America’s military and its civilian overseers is nothing new. America’s 220-year experiment in civilian control of the military is a recipe for friction. The nation’s history has seen a series of shifts in decision-making power among the White House, the civilian secretaries and the uniformed elite(精英). However, what may seem on the outside an unstable and special system of power sharing has, without a doubt, been a key to two centuries of military success. In the infighting dates to the revolution, George Washington waged a continual struggle not just for money, but to control the actual battle plan. The framers of the Constitution sought to clarify things by making the president the “commander in chief.”Not since Washington wore his uniform and led the troops across the Alleghenies to quell(镇压)the Whiskey Rebellion has a sitting president taken command in the field. Yet the absolute authority of the president ensures his direct command. The president was boss, and everyone in uniform knew it. In the Civil War, Abraham Lincoln dealt directly with his generals, and Secretary of War Edwin M. Stanton handled administrative details. Lincoln, inexperienced in military matters, initially deferred(顺从)to his generals. But when their caution proved disastrous, he issued his General War Order No. 1—explicitly commanding a general advance of all Union forces. Some generals, George B. McClellan in particular, bridled at his hands-on direction. But in constitutional terms, Lincoln was in the right. His most important decision was to put Ulysses S. Grant in charge of the Union Army in 1864. Left to its own timetable, the military establishment would never have touched Grant. The relationship between the president and his general provides a textbook lesson in civilian control and power sharing. Grant was a general who would take the fight to the enemy, and not second-guess the president’s political decisions. Unlike McClellan, for example, Grant cooperated wholeheartedly in recruiting black soldiers. For his part, Lincoln did not meddle in operations and did not visit the headquarters in the field unless invited. The balance set up by Grant and Lincoln stayed more or less in place through World War I. Not until World War II did the pendulum finally swing back toward the White House. Franklin Roosevelt, who had been assistant Navy secretary during World War I, was as well prepared to be commander in chief as any wartime president since George Washington.1.According to the author, the system of power sharing between the White House and the generals _____.A.is unstable and strangeB.is a guarantee for American military successC.has caused a series of quarrelsD.undermines the bases Of American military power正确答案:B解析:文章开头就指出,美国军界及其文职上司的矛盾由来已久,但是这个貌似脆弱的分享权力的体系,却是二百多年来美国军事胜利的保障。

一、文学术语*41.Epic叙事诗,史诗A long narrative poem telling about the deeds of a great hero and reflecting the values of the society fromwhich it originated.Many epics were drawn from an oral tradition and were transmitted by song and recitation before they were written down.Twoof the most famous epics of Western civilization are Homer's Iliad and Odyssey.The great epic of the Middle Ages is The DivineComedy(神曲)by the Italian poet Dante.The two most famous English epics are the Anglo-Saxon Beowulf and John Milton'sParadise Lost,which employ some of the conventions of the classical epic.2.Naturalism自然主义(文学、艺术以反映现实为宗旨)Naturalism is a term of literary history,primarily a French movement in prose fiction and the dramaduring the final thirdof the19th century,although it is also applied to similar movements or groups of writers in other countries in the later decades ofthe19th and early years of the20th cents.In France Emile Zola(1840-1902)was the dominant practitioner(习艺者,专业人员)of Naturalism in prose fiction and the chief exponent(鼓吹者,倡导者,拥护者;能手,大师)of its doctrines.The emergence of Naturalism does not mark a radical(彻底的)break with Realism,rather the new style is a logicalextension of it.Broadly speaking,Naturalism is characterized by a refusal to idealize experience and by the persuasion thathuman life is strictly subjected to natural laws.The Naturalists shared with the earlier Realists the conviction that the everydaylife of the middle and lower classes of their own day provided subjects worthy of serious literary treatment. Emphasis was laid onthe influence of the material and economic environment on behavior,and on the determining effects of physical and hereditaryfactors in forming the individual temperament.Famous American Naturalistic writers would include Jack London,Stephen Craneand Frank Norris,who were deeply influenced by Charles Darwin's evolution theory which believe that one's heredity and socialsituation limit one's character.3.Modernism现代派(盛行于20世纪的文学风格)Modernism was a complex and diverse international movement in all the creative arts,originating about the end of the19thcentury and prosperity in the20th century.The major themes of the modernist literature are the distorted, alienated and illrelationships between man and nature,man and society,man and man,and man and himself.The modernist writers concentratemore on the private than on the public,more on the subjective than on the objective.They are mainly concerned with the innerbeing of an individual.In their writings,the past,the present and the future are mingled(混合)together and exist at the sametime in the consciousness of an individual.4.Transcendentalism超验主义It was a reaction to the18th century Newtonian concept of the universe.The major features of New EnglandTranscendentalism can be summarized as follows:1.The Transcendentalists placed emphasis on spirit,or the Oversoul,as themost important thing in the universe.2.The Transcendentalists stressed the importance of the individual.To them the individualwas the most important element of society.3.The Transcendentalists offered a fresh perception of nature as symbolic of the Spiritor God.Nature was,to them,not purely matter.It was alive,filled with God's overwhelming presence.I.Major Literary Terms in The Anglo-Norman Period1.Romance:Any imaginative literature that is set in an idealized world and that deals with heroic adventures and battles betweengood characters and villains or monsters.Originally,the term referred to a medieval tale dealing with the loves and adventures ofkings and queens,knights and ladies,and including unlikely or supernatural happenings.Sir Gawain and the Green Knight is thebest of the medieval romances.John Keats's The Eve of St.Agnes is one of the greatest metrical(格律)romances ever written.2.Ballad(民谣,叙事歌谣):A story told in verse and usually meant to be sung.In many centuries,the folk ballad was one of theearliest forms of literature.Folk ballads have no known authors.They were transmitted orally from generation to generation andwere not set down in writing until centuries after they were first sung.The subject matter of folk ballads stems from the everydaylife of the common people.The most popular subjects,often tragic,are disappointed love,jealousy,revenge, sudden disaster

A Generalization of Paillier’s Public-Key Systemwith Applications to Electronic VotingIvan Damg˚ard,Mads Jurik and Jesper Buus NielsenAarhus University,Dept.of Computer Science,BRICSAbstract.We propose a generalization of Paillier’s probabilistic publickey system,in which the expansion factor is reduced and which allowsto adjust the block length of the scheme even after the public key hasbeenfixed,without losing the homomorphic property.We show thatthe generalization is as secure as Paillier’s original system and proposeseveral ways to optimize implementations of both the generalized andthe original scheme.We construct a threshold variant of the generalized scheme as well aszero-knowledge protocols to show that a given ciphertext encrypts oneof a set of given plaintexts,and protocols to verify multiplicative relationson plaintexts.We then show how these building blocks can be used for applying thescheme to efficient electronic voting.This reduces dramatically the workneeded to compute thefinal result of an election,compared to the previ-ously best known schemes.We show how the basic scheme for a yes/novote can be easily adapted to casting a vote for up to t out of L can-didates.The same basic building blocks can also be adapted to pro-vide receipt-free elections,under appropriate physical assumptions.Thescheme for1out of L elections can be optimized such that for a certainrange of the other parameter values,the ballotsize is logarithmic in L.1IntroductionIn[18],Paillier proposes a new probabilistic encryption scheme based on com-putations in the group Z∗n2,where n is an RSA modulus.This scheme has somevery attractive properties,in that it is homomorphic,allows encryption of many bits in one operation with a constant expansion factor,and allows efficient de-cryption.In this paper we propose a generalization of Paillier’s scheme using computations modulo n s+1,for any s≥1.We also show that the system can be simplified(without degrading security)such that the public key can consist of only the modulus n.This allows instantiating the system such that the block length for the encryption can be chosen freely for each encryption,independently of the size of the public key,and without losing the homomorphic property.The generalization also allows reducing the expansion factor from2for Paillier’s orig-inal system to almost1.We prove that the generalization is as secure as Paillier’soriginal scheme.We also provide a number of ways to optimize both the encryp-tion and decryption operations,in particular a new algorithm for encryption which,compared to a naive implementation of Paillier’s original scheme,saves a factor of4in computing time.In general,it saves a factor of4s compared to a straightforward implementation of the generalized system.We propose a threshold variant of the generalized system,allowing a number of servers to share knowledge of the secret key,such that any large enough subset of them can decrypt a ciphertext,while smaller subsets have no useful information.We prove in the random oracle model that the scheme is as secure as a standard centralized implementation.We also propose a zero-knowledge proof of knowledge allowing a prover to show that a given ciphertext encodes a given plaintext.From this we derive other tools,such as a protocol showing that a ciphertext encodes one out of a number of given plaintexts.Finally,we propose a protocol that allows verifica-tion of multiplicative relations among encrypted values without revealing extra information.We look at applications of this to electronic voting schemes.A large number of such schemes is known,but the most efficient one,at least in terms of the work needed from voters,is by Cramer,Gennaro and Schoenmakers[8].This protocol provides in fact a general framework that allows usage of any proba-bilistic encryption scheme for encryption of votes,if the encryption scheme has a set of”nice”properties,in particular it must be homomorphic.The basic idea of this is straightforward:each voter broadcasts an encryption of his vote(by sending it to a bulletin board)together with a proof that the vote is valid.All the valid votes are then combined to produce an encryption of the result,using the homomorphic property of the encryption scheme.Finally,a set of trustees (who share the secret key of the scheme in a threshold fashion)can decrypt and publish the result.Paillier pointed out already in[18]that since his encryption scheme is ho-momorphic,it may be applicable to electronic voting.In order to apply it in the framework of[8],however,some important building blocks are missing:one needs an efficient proof of validity of a vote,and also an efficient threshold vari-ant of the scheme,so that the result can be decrypted without allowing a single entity the possibility of learning how single voters voted.These building blocks are precisely what we provide here.Thus we immedi-ately get a voting protocol.In this protocol,the work needed from the voters is of the same order as in the original version of[8].However,the work needed to pro-duce the result is reduced dramatically,as we now explain.With the El-Gamal encryption used in[8],the decryption process after a yes/no election produces g R mod p,where p is prime,g is a generator and R is the desired result.Thus one needs to solve a discrete log problem in order tofind the result.Since R is bounded by the number of voters M,this is feasible for moderate size M’s.But √it requiresΩ(√for this in[8]is exponential in L in that it requires timeΩ(1All complexities given here assume that the length of challenges for the zero-knowledge proofs is at most k.dominated by the term10k log L.So already for moderate size elections we have gained a significant factor in complexity compared to[3].In[16],Hirt and Sako propose a general method for building receipt-free election schemes,i.e.protocols where vote-buying or-coercing is not possible because voters cannot prove to others how they voted.Their method can be applied to make a receipt-free version of the scheme from[8].It can also be applied to our scheme,with the same efficiency gain as in the non-receipt free case.When using the threshold version of our scheme,we assume for simplicity a trusted dealer for setting up the keys initially,and we assume that the modulus used is a safe prime product,similar to what is done in Shoup’s paper[19]. In[10],Damg˚ard and Koprowski propose techniques by which one can drop these restrictions from Shoup’s scheme,at the expense of an extra intractability assumption.The same idea can be easily applied to our scheme thus producing a scheme without a trusted dealer and using a general RSA modulus.The threshold version of our scheme can also be used for general secure multiparty computation as shown by Cramer,Damg˚ard and Nielsen in[4].3A Generalization of Paillier’s Probabilistic Encryption SchemeThe public-key crypto system we describe here uses computations modulo n s+1 where n is an RSA modulus and s is a natural number.It contains Paillier’s scheme[18]as a special case by setting s=1.Consider a modulus n=pq,p,q odd primes,where gcd(n,φ(n))=1.When p,q are large and randomly chosen,this will be satisfied except with negligible probability.Such an n will be called admissible in the following.For such an n,Z∗n s+1as a multiplicative group is a direct product G×H,where G is cyclicof order n s and H is isomorphic to Z∗n.This follows directly from the Chinese remainder theorem and the fact that Z∗p s+1is cyclic of order(p−1)p s.Thus,thefactor group¯G=Z∗n s+1/H is also cyclic of order n s.For an arbitrary elementa∈Z∗n s+1,we let¯a=aH denote the element represented by a in the factorgroup¯G.Lemma1.For any admissible n and s<p,q,the element n+1has order n s in Z∗n s+1.Proof.Consider the integer(1+n)i= i j=0 i j n j.This number is1modulo n s+1for some i if and only if i j=1 i j n j−1is0modulo n s.Clearly,this is the case if i=n s,so it follows that the order of1+n is a divisor in n s,i.e.,itis a number of form pαqβ,whereα,β≤s.Set a=pαqβ,and consider a term a j n j−1in the sum a j=1 a j n j−1.We claim that each such term is divisible by a:this is trivial if j>s,and for j≤s,it follows because j!can then not have p or q as prime factors,and so a must divide a j .Now assume for contradiction that a=pαqβ<n s.Without loss of generality,we can assume that this meansα<s.We know that n s divides a j=1 a j n j−1.Dividing both numbers by a, we see that p must divide the number a j=1 a j n j−1/a.However,thefirst term in this sum after division by a is1,and all the rest are divisible by p,so the number is in fact1modulo p,and we have a contradiction.Since then the order of H is relatively prime to n s the above lemma implies immediately that the element1+n)i=ψs(i,Z∗n).Thefinal technical observation we need is thatψcan be inverted given the factorization of n.In particular,taking discrete logarithms baseWe can notice that each term i j t+1 n t for j>t>0satisfies that i j t+1 n t= i j−1t+1 n t mod n j.This is because the contributions from k∗n j−1vanish modulo n j after multiplication by n.This means that we get:L((1+n)i mod n j+1)=(i j−1+k∗n j−1+ i j−12 n+...+i j−1j n j−1)mod n jThen we just rewrite that to get what we wantedi j=i j−1+k∗n j−1=i j−1+L((1+n)i mod n j+1)−(i j−1+ i j−12 n+...+ i j−1j n j−1)mod n j=L((1+n)i mod n j+1)−( i j−12 n+...+ i j−1j n j−1)mod n j This equation leads to the following algorithm:i:=0;for s dot1:=L(a mod n j+1);t2:=i;for j doi:=i−1;t2:=t2∗i mod n j;t1:=t1−t2∗n k−1i:=t1;endn s mod n=r aλ+1mod n=(rλ)a r mod n=r mod n=r.We are now ready to describe our crypto system.In fact,for each natural number s,we can build a crypto system CS s,as follows:Key Generation On input the security parameter k,choose an admissible RSAmodulus n=pq of length k bits2.Also choose an element g∈Z∗n s+1suchthat g=(1+n)j x mod n s+1for a known j relatively prime to n and x∈H.This can be done,e.g.,by choosing j,x at randomfirst and computing g;some alternatives are described later.Letλbe the least common multiple of p−1and q−1.By the Chinese Remainder Theorem,choose d such thatd mod n∈Z∗n and d=0modλ.Any such choice of d will work in thefollowing.In Paillier’s original scheme d=λwas used,which is the smallest possible value.However,when making a threshold variant,other choices are better-we expand on this in the following section.Now the public key is n,g while the secret key is d.Encryption The plaintext set is Z n s.Given a plaintext i,choose a random r∈Z∗n,and let the ciphertext be E(i,r)=g i r n s mod n s+1.Decryption Given a ciphertext c,first compute c d mod n s+1.Clearly,if c= E(i,r),we getc d=(g i r n s)d=((1+n)ji x i r n s)d=(1+n)jid mod n s(x i r n s)d modλ=(1+n)jid mod n sNow apply the algorithm from the proof of Theorem1to compute jid mod n s.Applying the same method with c replaced by g clearly produces the value jd mod n s,so this can either be computed on thefly or be saved as part of the secret key.In any case we obtain the cleartext by(jid)·(jd)−1=i mod n s.Clearly,this system is additively homomorphic over Z n s,that is,the product of encryptions of messages i,i is an encryption of i+i mod n s.To facilitate comparison with Paillier’s original system,we have kept the above system description as close as possible to that of Paillier.In particular, the description allows choosing g in a variety of ways.However,as we shall see, semantic security of the system is equivalent to a particular computational as-sumption,no matter how we choose g,in particular we may as well simplify matters and choose g=n+1always.This also allows a more efficient imple-mentation.Therefore,in the following sections,when we refer to CS s,we usually mean the above system with g=n+1.3.1SecurityThere are two basicflavors or strengths of security that one may consider,namely–Is the scheme one-way,i.e.,is it hard to compute the plaintext from the ciphertext?–Is the scheme semantically secure,i.e.,does any information at all about the plaintext leak,given the ciphertext?We givefirst a short informal discussion on one-wayness,and then look at se-mantic security in more detail.The homomorphic property of the scheme means that the problem of com-puting the plaintext from the ciphertext(and the public key)is random self-reducible:given any ciphertext c and public key n,g,one may choose i∈Z n s,j∈Z∗n s,r,r ∈Z∗n at random and try to decrypt the ciphertext c = cg i r n s mod n s+1with respect to public key n,g where g =g j r n s mod n s+1.Ifthis succeeds,one canfind the original plaintext by multiplying by j and sub-tracting i modulo n s.Note that c ,g is a random ciphertext-generator pair,no matter how c,g were chosen.So any algorithm that can break a non-trivial frac-tion of the ciphertexts and choices of g can also break a random instance with significant probability.This motivates calling our scheme one-way if it is hard tofind the plaintext given a random public key n,g and a random ciphertext c.We haveProposition1.If for some t the scheme CS t is one-way,then CS s is one-wayfor any s>t.Especially CS s is one-way for any s if Paillier’s original scheme CS1is one-way.Proof.Assume that s>t and that CS t is one-way.Assume for the sake of contradiction that CS s is not one-way.Then given a public key n,g and a ci-phertext c t from CS t,we can transform this to a decryption problem in CS s instead.Concretely this means we consider c t as a number modulo n s+1(insteadof n t+1),and choose as the public generator a random number˜g∈Z∗n s+1,suchthat˜g mod n t+1=g.We then randomize c t(modulo n s+1)as described above. This produces a random instance of the decryption problem in CS s,so by as-sumption we canfind the plaintext m in CS s corresponding to c t.We have of course that m∈Z n s,and now clearly m mod n t is the plaintext corresponding to c t in CS t,so that CS t is not one-way either.If we want to claim that a cryptosystem“hides”the plaintext in any reason-able sense,the one-way assumption is essentially the weakest possible assumption one can make.In[7],Catalano,Gennaro and Howgrave-Graham show that this assumption for CS1implies that one can make a semantically secure system hiding a logarithmic number of bits per ciphertext in the original system,and that a somewhat stronger assumption implies a system hiding a linear number of bits per ciphertext.It is easy to generalize these results to CS s.None of the schemes constructed this way will be homomorphic,however.The semantic security of our schemes can be based on the following assump-tion,introduced by Paillier in[18],the decisional composite residuosity assump-tion(DCRA):Conjecture1.Let A be any probabilistic polynomial time algorithm,and assume A gets n,x as input.Here n has k bits,and is chosen as described above,and xis either random in Z∗n2or it is a random n’th power in Z∗n2(that is,a randomelement in the subgroup H defined earlier).A outputs a bit b.Let p0(A,k)bethe probability that b=1if x is random in Z∗n2and p1(A,k)the probabilitythat b=1if x is a random n’th power.Then|p0(A,k)−p1(A,k)|is negligible in k.Here,“negligible in k”as usual means smaller than1/f(k)for any polynomial f()and all large enough k.We now discuss the semantic security of CS s.There are several equivalent formulations of semantic security.We will use the following:Definition1.An adversary A against a public-key crypto system gets the pub-lic key pk generated from security parameter k as input and outputs a mes-sage m.Then A is given an encryption under pk of either m or a message chosen uniformly in the message space,and outputs a bit.Let p0(A,k),re-spectively p1(A,k)be the probability that A outputs1when given an encryp-tion of m,respectively a random encryption.Define the advantage of A to be Adv(A,k)=|p0(A,k)−p1(A,k)|.The crypto system is semantically secure if for any probabilistic polynomial time adversary A,Adv(A,k)is negligible in k.In[18],Paillier showed that his crypto system(which is equivalent in security to our CS1)is semantically secure if and only if DCRA holds.This holds for any choice of g,and follows easily from the fact that given a ciphertext c that is either random or encrypts a message i,we have that cg−i mod n2is eitherrandom in Z∗n2or a random n’th power.In particular,assuming DCRA,onemay choose g=n+1always without degrading security.We now show that security of CS s is equivalent to DCRA:Theorem2.For any s,the crypto system CS s is semantically secure if and only if the DCRA is true.This holds even if s is allowed to increase polynomially in the security parameter.Proof.From a ciphertext in CS s,one can obtain a ciphertext in CS1by reducing modulo n2,this implicitly reduces the message modulo n.It is therefore clear that if DCRA fails,then CS s cannot be secure for any s.For the converse,we assume that CS s is not secure and we start by showing a relation between security of CS s and that of CS t for values of t<s.The message space of CS s is Z n s.Thus any message m can be written in n-adic notation as an s-tuple(m s,m s−1,...,m1),where each m i∈Z n and m= s−1i=0m i+1n i.Let D n(m s,...,m1)be the distribution obtained by encrypting the message(m s,...,m1)under public key n.If one or more of the m i are replaced by∗’s,this means that the corresponding position in the message is chosen uniformly in Z n before encrypting.Now,assume for simplicity that s is even,consider any adversary A against CS s,and assume that Adv(A,k)≥1/f(k)for some polynomial f()and infinitelymany values of k.For any such value,we can assume without loss of generality, that we have p0(A,k)−p1(A,k)≥1/f(k).Suppose we make a public key n from security parameter k,show it to A,get a message(m s,...,m1)from A and show A a sample of D n(∗,...,∗,m s/2,...,m1).Let q(A,k)be the probability that A now outputs1.Of course,we must have(∗)p0(A,k)−q(A,k)≥12f(k)and one of these cases must be true for infinitely many values of k.In thefirst case in(∗),we can make a successful adversary against CS s/2,as follows:we get the public key n,show it to A,get(m s,...,m1),and return(m s,...,m1+s/2)as output.We will get a ciphertext c that either encrypts(m s,...,m1+s/2)in CS s/2,or is a random ciphertext.If we consider c as an element in Z∗n s+1,we know itis an encryption of some plaintext,which must have either(m s,...,m1+s/2)or s/2random elements in its least significant positions.Hence c n s/2mod n s+1is an encryption of(m s,...,m1+s/2,0,...,0)or(∗,..,∗,0,...,0).We then make a random encryption d of(0,..,0,m s/2,...,m1),give c n s−1d mod n s+1to A and return the bit A outputs.Now,if c encrypts(m s,...,m1+s/2),we have shown to A a sample of D n(m s,...,m1),and otherwise a sample of D n(∗,m s/2,...,m1).So by assumption on A,this breaks CS1with an advantage of1/2f(k)for infinitely many k.In the second case of(∗),we can also make an adversary against CS s/2,as follows:we get the public key n,show it to A,and get a message(m s,...,m1).We output(m s/2,...,m1)and get back a ciphertext c that encrypts in CS s/2either (m s/2,...,m1)or something random.If we consider c as a number modulo n s+1, we know that the corresponding plaintext in CS s has either(m s/2,...,m1)or random elements in the least significant s/2positions-and something unknown in the top positions.We make a random encryption d of(∗,..,∗,0,...,0),show cd mod n s+1to A and return the bit A outputs.If c encrypted(m s/2,...,m1),we have shown A a sample from D n(∗,..,∗,m s/2,....,m1),and otherwise a sample from D n(∗,...,∗).So again this breaks CS s/2with an advantage of1/2f(k)for infinitely many k.To sum up,we have:for any adversary A against CS s,s even,there exists an adversary A against CS s/2,such that Adv(A ,k)≥1/2f(k)for infinitely many k.Similarly,for odd s,we can show existence of an adversary against either CS(s+1)/2or CS(s−1)/2with advantage at least1/2f(k)for infinitely many k.Repeated use of this result shows that for any adversary A against CS s,there exists an adversary against CS1with advantage at least1/2sf(k)for infinitely many k.Thus,since s is polynomially bounded as a function of k,CS1is not semantically secure,and this contradicts Paillier’s original result.From the point of view of exact security analysis,one can note that from the proof above,it follows that the maximal advantage with which CS s can be broken is at most a factor of2s larger than the corresponding advantage for CS1. Thus,there is no great security risk in using large values of s,if one believes that CS1is secure in thefirst place.3.2Adjusting the Block lengthAs mentioned,we may choose g=n+1always without losing security,and the public key may then consist only of the modulus n.This means that we can decide on a value for s at any point after the keys have been generated,or even let the sender decide on thefly when he encrypts a message.Concretely,the system will then work as follows:Key Generation Choose an admissible RSA modulus n=pq.Now the public key is n while the secret key isλ,the least common multiple of(p−1)and (q−1).Encryption Given a plaintext i represented as a non-negative integer,choosea s such that i<n s,choose a random r∈Z∗n,and let the ciphertext beE(i,r)=(1+n)i r n s mod n s+1.Decryption Given a ciphertext c,compute cλmod n s+1(note that from the length of c,one can decide the correct value of s except with negligible probability).Clearly,if c=E(i,r),we getcλ=((1+n)i r n s)λ=(1+n)iλmod n s(r n s)λmodλ=(1+n)iλmod n s+1 Now apply the algorithm from Theorem1to compute iλmod n s and get the message by multiplying byλ−1modulo n s.It is an immediate corollary to Proposition1and Theorem2that the above scheme is one-way if CS1is one-way respectively is semantically secure if the DCRA holds.4Some Optimizations and Implementation Issues4.1An Alternative Encryption FunctionLetψs:Z n s×Z∗n→Z∗n s+1be the isomorphism given by(x,r)→(1+n)x r n s mod n s+1in Lemma2.In the above we encrypt an element i∈Z n s by a random element from the coset(Using standard techniques we can generate a random RSA modulus n=pq with known p and q such that p=3mod4,q=3mod4,gcd(p−1,q−1)=2. This means that the subgroup of quadratic residues SQ(n)is cyclic and has odd order,sayα.We can also ensure that all elements in this subgroup-except for a negligible fraction-are generators.This can be done by picking p,q such that all prime factors in p−1,q−1except2are sufficiently large.One extreme special case of this is when n is a safe prime product,which is an option we use later for the threshold version of the scheme.Let Z∗n[+]be the elements with Jacobi symbol1in Z∗n.We have that Z∗n[+] contains SQ(n),has order2αand is also cyclic.Finally,−1∈Z∗n[+]\SQ(n)by choice of n.All this implies that if we choose at random x∈Z∗n and let h=−x2mod n then,except with negligible probability, h =Z∗n[+].This then allows us to generate a uniformly random element r from Z∗n[+]as h a mod n,where a is a uniformly random integer from[0,(p−1)(q−1)/2).However,since(p−1)(q−1)/2 is the secret key,this would allow only the owner of the secret key to en-crypt,which would of course be useless.We can remedy this by using a result from[13].Let(n,h)be generated as above.Let a be a uniformly random inte-ger from[0,(p−1)(q−1)/2)and let a be a uniformly random element from [0,2 k/2 ).Then by[13,Theorem3.2]the random variables(n,h,h a mod n)and (n,h,h a mod n)are computationally indistinguishable assuming the intractabil-ity of factoring,which is implied by the DCRA.This means that even though h a mod n is not a uniformly random element from Z∗n[+],it cannot be distin-guished from a uniformly random element from Z∗n[+]by any polynomial time algorithm,which suffices for our application.This gives us the following crypto system CS s.Key Generation Choose an admissible RSA modulus n=pq of length k bits, where p≡q≡3(mod4),gcd(p−1,q−1)=2,and such that a random square generates SQ(n)except with negligible probability.Choose a gener-ator h of Z n[+]as described above.Now the public key is(n,h)while the secret key isλ=(p−1)(q−1)/2,the least common multiple of(p−1)and (q−1).Encryption Given a plaintext i∈Z n s choose a random a∈Z2 k/2 and let the ciphertext be˜E(i,a)=(1+n)i(h a mod n)n s mod n s+1=E(i,h a mod n). Decryption As before.The following theorem follows directly from the fact that h a mod n is pseudo-random in Z∗n under DCRA,that h can be generated given just n,and that the security of CS s is unchanged when restricting the randomness to Jacobi symbol 1.Theorem3.For any s,the crypto system CS s is semantically secure if and only if the DCRA is true.This holds even if s is allowed to increase polynomially in the security parameter.From an exact security point of view,one should be aware that in order to argue the security,we are using the DCRA twice:first to argue that CS s is assecure as CS s(namely h a mod n is pseudorandom)and then to argue that CS s is secure.This means that if we want to build instances of CS s that can be broken with advantage no larger than instances of CS s with security parameter k,we need to use moduli that are somewhat longer than k bits.How much longer depends on exactly how strong assumptions we are willing to make,and on the complexity of the reduction in the result of[13].This may partly eliminate the efficiency advantage we show below for CS s.On the other hand,this issue can be completely avoided by using more randomness,namely we choose a as a random number modulo n/2,instead of a random k/2-bit number.Then h a mod n will be statistically close to a random element in h ,without any assumptions,and up to a negligible term,we have the same security for this variant of CS s as for CS s.This will only cost a factor of2in performance of the encryption.4.2Optimizations of Encryption and DecryptionEncryption.While encrypting,instead of computing(1+n)m directly,we can can compute it according to:(1+n)m=1+mn+ m2 n2+...+ m s n s mod n s+1this trades an exponentiation with a O(n s)size exponent for O(s)multiplications by calculating the binomials using:m j = m j−1 m−j+1j:=2tobeginIn the crypto system CS s the elements from H is generated as(h a mod n)n s mod n s+1which,if computed naively,certainly leads to no optimization. However,a simple observation allows us to reduce the number of steps used in this computation.Let h s=h n s mod n s+1.Then using the isomorphism from Theorem1,we have(h a mod n)n s mod n s+1=ψs(0,h a mod n)=ψs(0,h)a=h a s mod n s+1It follows that˜E(i,a)=(1+n)i h a s mod n s+1.If we precompute and save h s,then using standard methods for exponentiation with afixed base,h a s mod n s+1can be computed by an expected number of k/4multiplications modulo n s+1and hence the entire encryption can be done in k/4+2s pared to a straightforward implementation of CS s with the same k value,where2full scale exponentiations are made,this saves a factor of about4s in computing time,and in particular this is four times as fast as Paillier’s original system. Decryption.The technique of precomputing factors in binomial coefficients to make encryption faster also applies to the corresponding computations in decryption(see the algorithm in the proof of Theorem1).Also in the same way as with encryption,we can exploit the fact that the algorithm involves modular multiplication of a variable by a power of n,which means the value of that variable only needs to be known modulo a smaller power of n.Another thing that can be optimized is the use of the L function.In the algorithm from Theorem1the L function is calculated once per iteration of the for-loop.Instead of doing this we can calculate the largest of these:L(a mod n s+1)and use the property that L(a mod n j+1)=L(a mod n s+1)mod n j.This means that we can remove all but1of the division and the modular reductions we make are smaller.The standard trick of splitting the computations up and doing them modulo relatively prime parts of the modulus can also be used here with the moduli p j and q j in the j’th run of the outer loop.One should be aware though that we need to use different L functions for p and q,namely L q(a)=((a−1mod q s+1)/q)·p−1mod q s and L p(a)=((a−1mod p s+1)/p)·q−1mod p s.In this case,decryption can be speeded up by precomputing p j,q j for1≤j≤s,and the n k−1k!−1mod p j,n k−1k!−1mod q j for2≤k≤j≤s. Performance Evaluations.Infigure1and2the generalized crypto system is compared to the El-Gamal and RSA crypto systems.The table is focused on afixed plaintext size and variable size of security parameter for the general-ized cryptosystem.This comparison corresponds to a scenario where you need a certainfixed plaintext size(for instance a large scale election)and it might be sufficient with a smaller security parameter.It shows that if the security param-eter doesn’t need to have the same size as the encryption block then a significant performance improvement can be achieved.Infigure3there is a comparison with the number of milli-seconds it takes to encrypt a bit using same security parameter,but a variable block size.It shows that using El-Gamal and the generalized crypto system achieves almost the same rates of encryption.It also shows-as expected-that the encryption time per bit increases somewhat with larger s values.Thus,if small ciphertext expansion and large block size is important,this can be achieved at a reasonable performance penalty;but if speed is the only important parameter,s=1is the best choice.。
