学术英语summarizing
学术英语summarizingSummarizing in academic English refers to the process of condensing and presenting the key points, ideas, or arguments from a longer piece of text in a shorter and more concise form. It involves extracting the essential information and presenting it in a clear and organized manner. The goal of summarizing is to provide a concise overview of the main content without losing the integrity or significance of the original text.When summarizing academic English, it is important to follow certain guidelines and techniques to ensure clarity and accuracy. Here are some key elements to consider:1. Identify the main ideas: Read the text carefully and identify the central themes, arguments, or points that the author is trying to convey.2. Paraphrase rather than quote: Instead of directly quoting the text, paraphrase the main ideas in your own words. This helps to demonstrate your understanding of the content.3. Include key details: Include important details, examples, or supporting evidence that are relevant to the main ideas. However, be selective and avoid including excessive details that may make the summary overly long.4. Use transitions: Use transitional words or phrases to connect the different ideas and ensure the summary flows smoothly.5. Maintain coherence: Ensure that the summary is coherent and makes sense asa standalone document. It should convey the overall message of the original text in a clear and concise manner.6. Edit and proofread: After writing the summary, review it for clarity, accuracy, and conciseness. Edit and remove unnecessary words or sentences to make it more impactful.Summarizing academic English requires practice and a good understanding of the text. By following these guidelines, you can effectively summarize complexinformation and convey the key points in a clear and concise manner.。

442LectureSummaries
Lecture SummariesThe descriptions below will summarize what we did up to now and will give the plan for the upcoming lecture. It will also suggest optional reading for each lecture. Sometimes this reading will include more information than what we covered (and than you probably need to know). Some of this information should indeed be skipped (it is too deep for our introductory course), while some other will contain the proofs and discussion that is useful, but was not done in class due to the lack of time. You should use your intellegence to skip the ``unclear (advanced) parts'' and extract the useful information. Do not worry, it is usually very easy to do.∙Lecture 1 . Problem of secret communication. One-time pad and Shannon impossibility result. Modern Cryptography: computationally boundedadversaries. Private-Key vs. Public-Key Cryptography. In search of public-key solution: motivation for one-way functions and trapdoor permutations.Definitions.Read: this web page, [GB notes, chap. 1, sec. 6.3-6.4, 2.1-2.2].Lecture 2. Examples of one-way functions: RSA, Modular Exponentiation,Integer Multiplication, Modular Squaring. Applications: UNIX passwordauthentication, S/Key one-time password system. Problems with using (iterated) one-way (trapdoor) permutations for both puclic- and private-key ecnryption.Main problems and criticism of one-way functions: reveal partial information, not ``pseudorandom''.Read: [GB notes, sec. 2.3, 7.2].∙Lecture 3 . Brish-up on number theory. Primes vs. composites, easy and hard problems. RSA, discrete log, factoring, square root extraction. Chineseremainder theorem. Primality tests.Read: refresh number theory (handouts in class, skim appendix C in [GBnotes]).∙Lecture 4 . Motivation to hardcore bits. Examples: MSB for discrete log, LSB for squaring. Definition. General construction (Goldreich-Levin). Gettingmore bits out: construction based on hardcore bits of one-way permutations.Informal Applications to public- and secret-ket encryption. Definitions ofpseudorandom generators. Definition of next-bit test.Read: [GB notes, sec. 2.4, 3.0-3.2].∙Lecture 5 .

Equivalence to OWF's. Forward-Secure PRG's:generic construction is forward-secure, builing forward-secure PRG from anyPRG, application to secret-key encryption.Read: [GB notes, sec. 3.3-3.4].∙Lecture 6 . Public-Key encryption. Problems with TDP approach and deterministic encryption in general. Encrypting single bits, definition ofindistinguishability. Scheme based on TDP's.

The problem of authentication. Message authentication codes (MACs). Definition of security: existential unforgeability against chosenmessage attack. Construction using PRFs. Unpredictable functions, theirrelation to MACs and PRFs. Reducing MAC length: using e-universal hash functions (e-UHFs) and e-xor-universal hash functions. Examples of UHFs: information-theoretic examples, XOR-MAC, CBC-MAC. A glimpse at CCA security and using MAC to go from CPA to CCA.Read: [GB notes, chap. 8, sec. 6.10-6.11]∙Lecture 12 . Moving to public-key: digital signatures. Definitions, RSA and Rabin's signatures. Trapdoor approach and its deficiency. Signature paradox and its resolution.

Practicalsignature without random oracles: Cramer-Shoup scheme.Read: [GB notes, sec. 9.5-9.5.7, 9.5.12]∙Lecture 14 . Commitment Schemes. Definition and properties. Increasing input size: bit-by-bit composition, hash-then-commit technique using CRHF's.Constructions: from (1) OWF's, (2) OWP's, (3) CRHF's and (4) Pedersencommitment (based on DL). Relaxed commitments and composition usingUOWHF's. Applications: bidding, coin-flipping, parallel authenticatedencryption, password authentication, zero-knowledge. Introduction to Zero-Knowledge (ZK). Motivation and quadratic residue example. Proof that NP belongs to CZK using commitments. Making password authentication with OWFs or commitments an identification scheme using ZK.What's next? (never happened). Many things we did NOT cover... More ZK.Protocols - huge! Identification protocols, OT and PIR, RO model (incl.OAEP and Fiat-Shamir heuristics), CCA and non-malleability, secret sharing and VSS, threshold crypto, multiparty computation and SFE (incl. coin-flipping), gadgets (trapdoor commitments, deniable encryption, blindsignatures, etc.)...

（完整word版）英语学术演讲与写作4篇Summary
（完整word版）英语学术演讲与写作4篇SummarySummary of ‘scientists shouldn’t be surprised by the popularity of intelligent d esign’In his article ’’ which addresses many scientists , grumps over the persistence of ID(in telligent design), scott Lilienfeld postulates that many Americans, approval of ID cann ot be blamed on their lack of common sense but rather their dependence on their com mon sense or intuition in making judgments which turns them awayfrom the theory of natural selection. According to Lilienfeld ,the difficulty in intuiting how marvelous cr eatures and organisms have resulted from natural selection has prevented many Ameri cans from accepting Darwinian Theory while the same common sense has made ID ra ther tempting to them.As is indicated by a multitude of examples of wrong beliefs bas ed on common sense, intuition does not provide a reliable means of understanding the world. Unfortunately, scientists and science educators have failed to teach research m ethods and academic skills that can help debunk misconceptions compatible with peo ple,s common sense. Finally , Lilienfeld concludes that a radical shift in science educa tion has to be initiated so that scientists would not face a fiasco when confronting erro neous claims refuged by people,s common sense.Summary of ‘Empowerment and Restraint in Scientific Communication’In his article “”, Philip Campbell highlights a dire likely consequence of biologists ” increased ability to obtain a nd distribute scientific information that such informatio n may be exploited by people with heinous intentions. Scientificcommunication, acco rding to Campbell, has seen significant development due to the invention of powerful software and hardware that f acilitate scientists” acquisition of information and reduc e the trouble they may otherwise have to take in order to publicize their research. Ho wever, the resulting plethora of biological information spawns a hazard that the infor mation may be used to build biological weapons, and this hazard has come to peoples attention with synthetic biologys recent development. Campbell points out that it is rel atively easy to abuse biological knowledge while biological studies often bring about unexpected results.People using biological information for malicious purpose may be whoever have learnt to exploit simple biological technologies and are not necessarily committed to terrorist agendas. Campbell believes that the decisions made by funding agencies and scientific journals who are the gatekeepers of biological research will be crucial in reducing the risks of information abuse and what proactive measure should be taken has to be considered by all related parties.Summary of ‘ethical, legal and social implications of autonomous systems’In his article“”Austin Modine highlights that robot driver will control the vehicles whi ch raises problems in different social levels.Autonomous robots will deprive people of their control.For Modines assume that human interaction is necessary,but human will make mistakes because of their wrong decision.Autonomous systems also have a tend ency to make mistake.And there is a problem that who will be responsible for the failu re.A concern that autonomous systems are held back until they dont make mistakes an y more.The reaction to failures between autonomous systems and manned systems sh ould be chosen if it make lessmistakes than human-operators and technical systems.F inally,Austine Modine conclude that many questions should be solved in order to mak e autonomous systems accept legally and socially.Summary of ‘why do things become more complex’In his article “Why Do Things Become More Complex” Carrington highlights a ph enomenon that simplicity becomes more complex, and people are interested in the co mplexity. In the history, the turbojet engine invented by Frank Whittle just use a simpl e compressor-turbine combination as the motivation. After many years, the jet engine changed more complicated as the pressure of commercial and military interests, usuall y by adding a subsystem. Modern engines have a vastly complex array of interconnect ed subsystems subassemblyes. The jet engines work like a cheetah both in the outside and inside, sleekly and complicatedly. In the process of growing complexity, it has ma ny obstacle for people to overcome, such as new bureaucratic offices and departments . The complexity brings a mass of problems to keep the performance like maintenance repairs, et.al.. And functions and modifications tends to increase complexity through overcoming limitations, abnormal circumstances and adapting to the complex world. The renewable simplicity often emerges slowly after the growing complication. Finall y, Carrington concludes that complexity should be checked so that it can evolves natur ally and deliver powerful performance. And also need to final things to bring renewab le simplicity after the complexity.。
