Here comes the role of data structures. They provide a way to organize and store datain such a way that it can be easily accessed and manipulated. By choosing appropriate data structures, programmers can optimize the performance of theiralgorithms, leading to faster execution times and more efficient resource utilization.There are several types of data structures, each with its unique characteristics and use cases. One of the most basic data structures is the array, which stores elements of the same type in contiguous memory locations. Arrays are widely used due to their simplicity and constant-time access to elements. Another commonly used data structure is the linked list, which consists of nodes where each node contains a data field and a reference (or pointer) to the next node in the sequence. Linked lists are efficient for insertion and deletion operations but may have slower access times compared to arrays.Apart from arrays and linked lists, there are more complex data structures such as stacks, queues, trees, and graphs. Stacks follow the Last-In-First-Out (LIFO)principle and are often used in algorithms involving function calls, expression evaluation, and backtracking. Queues, on the other hand, adhere to the First-In-First-Out (FIFO) principle and are commonly used in scenarios liketask scheduling, job processing, and breadth-first search algorithms. Trees are hierarchical data structures consisting of nodes connected by edges, with a root node at the top and leaf nodes at the bottom. They are utilized in applications like hierarchical data storage, binary search trees, and decision trees. Graphs are collections of nodes (vertices) and edges connecting these nodes, and they find applications in various fields such as social networks, routing algorithms, and network flow optimization.Now, let's discuss the applications of data structures across different domains. In software development, data structures are extensively used in designing databases, implementing algorithms, and building user interfaces. For example, databases rely on data structures like B-trees and hash tables for efficient storage and retrieval of information. In algorithm design, efficient data structures are crucial for optimizing time and space complexity. Many popular algorithms such as sorting, searching, and graph traversal algorithms heavily rely on data structures for their implementation. Moreover, in user interface development, data structures like trees and graphs are usedto represent the hierarchical structure of UI components and their relationships.In addition to software development, data structures find applications in fields like artificial intelligence, bioinformatics, and computational biology. In artificial intelligence, data structures are used to represent knowledge, make decisions, and solve complex problems. For instance, knowledge graphs are used to represent relationships between entities in a knowledge base, while decision trees are employed in decision-making processes. In bioinformatics and computational biology, data structures are used to store and analyze biological data such as DNA sequences, protein structures, and metabolic pathways. Efficient data structures and algorithms are essential for tasks like sequence alignment, genome assembly, and protein folding prediction.In conclusion, data structures are the building blocks of computer science. They enable efficient storage, retrieval, and manipulation of data in computer programs, leading to faster execution times and more efficientresource utilization. With various types of data structures available and their applications spanning across different domains, it is evident that a solid understanding of data structures is essential for every computer scientist and software developer. By mastering data structures and their applications, programmers can write more efficient and scalable software solutions, thereby advancing the field of computer science as a whole.(翻译)。

More Efficient Software Implementations of (Generalized) DES
Interner Bericht 18/90 May 1990
Abstract
By preserving the macro structure of the Data Encryption Standard (DES), but by allowing the user to choose 1. 16•48 independent key bits instead of generating them all using only 56 key bits, 2. arbitrary substitutions S 1, ..., S8 and 3. arbitrary permutations IP and P, and 4. an arbitrary expanding permutation E, we obtain a very general and presumably much stronger cipher called generalized DES, or G-DES for short. A cipher having the first three extensions is called G-DES with non-arbitrary E. We choose, in an unorthodox way, from some well known equivalent representations of G-DES and some well suited table combinations and implementations. Concatenations of substitutions and permutations are precomputed and tabulated. Since direct tabulation of e.g. a permutation of 32 bits requires 232 entries of 4 bytes each, which clearly exceeds the main memories of today, the big table is split into smaller ones that permute disjoint and compact parts of the input bits at the appropriate positions. To compute an entry in the big table, the corresponding entries in the smaller tables are ORed. For some specific expanding permutations (including the original E in DES), the expense of this permutation can be reduced drastically: Only copy, rotate, and AND with a mask of a register is necessary, if the bits in the register and the tables of the substitutions are ordered appropriately. Since this is the only way to achieve better performance for DES than for G-DES we know, it does not seem to make sense to implement anything more narrow in software than G-DES with non-arbitrary E.

II Using these techniques, we get by far the fastest software implementations of DES (more specifically: G-DES with non-arbitrary E) and G-DES known to us. The same DES and G-DES implementations, partly in MC68000 assembler language, achieve 87 and 68 kbit/s on an Apple Macintosh Plus (MC68000, 7.83 MHz), 104 and 81 kbit/s on an Apple Macintosh SE (MC68000, 7.83 MHz), 208 and 162 kbit/s on an Apple Macintosh Portable (MC68000, 15.67 MHz), 445 and 327 kbit/s on an Apple Macintosh II (MC68020, 15.67 MHz), 487 and 366 kbit/s on an Apple Macintosh IIx, IIcx, or SE/30 (MC68030, 15.67 MHz), 722 and 546 kbit/s on an Apple Macintosh IIci (MC68030, 25 MHz, no cache board), 829 and 597 kbit/s on an Apple Macintosh IIci (MC68030, 25 MHz, with 64 Kbyte cache board) in ECB and CBC mode using less than 110 and 430 Kbytes main memory. OFB(64) mode is between 19 and 28% faster because we can save IP, except for the first time. Conversely, if CBC mode is used for authentication, we can save IP-1 except for the last block. This increases speed by between 11 and 12%. To avoid unnecessary IP and IP-1 executions and to enable multiple encryption in all modes of operation, our implementation supports multiple encryption, which may be necessary if (standard) DES is used. To give an example: triple encryption with G-DES in ECB and CBC mode is performed with 28 kbit/s, 32 kbit/s, 64 kbit/s, 140 kbit/s, 154 kbit/s, 230 kbit/s, and 254 kbit/s, respectively, for the 7 Macintosh configurations mentioned above. Our table implementation makes it possible to save key EORing (Exclusive OR = addition mod 2) in each round by precomputing a key-specific table for every (or in some cases only every second) round. This costs 1 Mbyte main memory and increases cipher speed by 9% on the Macintosh Plus and by 7% on the Macintosh II, respectively. For MC680xy machines without a data cache or memory management unit, or if their capacity sufficiently exceeds 1 Mbyte, this is the next step in a speed vs. main memory trade-off. Memory requirements can be reduced by not copying bits which are input to one combined Sbox. For G-DES with non-arbitrary E, this reduces the use of main memory to less than 300 Kbytes and increases cipher speed by 16% on the Macintosh Plus, SE or Portable and by 20% both on the Macintosh II and IIx, IIcx or SE/30 and by 17% on the Macintosh IIci without cache board.
