Book Synopsis Cryptography by : Douglas Robert Stinson
Download or read book Cryptography written by Douglas Robert Stinson and published by CRC Press. This book was released on 2018-08-14 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: Through three editions, Cryptography: Theory and Practice, has been embraced by instructors and students alike. It offers a comprehensive primer for the subject’s fundamentals while presenting the most current advances in cryptography. The authors offer comprehensive, in-depth treatment of the methods and protocols that are vital to safeguarding the seemingly infinite and increasing amount of information circulating around the world. Key Features of the Fourth Edition: New chapter on the exciting, emerging new area of post-quantum cryptography (Chapter 9). New high-level, nontechnical overview of the goals and tools of cryptography (Chapter 1). New mathematical appendix that summarizes definitions and main results on number theory and algebra (Appendix A). An expanded treatment of stream ciphers, including common design techniques along with coverage of Trivium. Interesting attacks on cryptosystems, including: padding oracle attack correlation attacks and algebraic attacks on stream ciphers attack on the DUAL-EC random bit generator that makes use of a trapdoor. A treatment of the sponge construction for hash functions and its use in the new SHA-3 hash standard. Methods of key distribution in sensor networks. The basics of visual cryptography, allowing a secure method to split a secret visual message into pieces (shares) that can later be combined to reconstruct the secret. The fundamental techniques cryptocurrencies, as used in Bitcoin and blockchain. The basics of the new methods employed in messaging protocols such as Signal, including deniability and Diffie-Hellman key ratcheting.

Book Synopsis A Very Compact Rijndael S-Box by : D. Canright
Download or read book A Very Compact Rijndael S-Box written by D. Canright and published by . This book was released on 2004-09-01 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: One key step in the Advanced Encryption Standard (AES), or Rijndael, algorithm is called the "S-box", the only nonlinear step in each round of encryption/decryption. A wide variety of implementations of AES have been proposed, for various desiderata, that effect the S-box in various ways. In particular, the most compact implementation to date of Satoh et al. performs the 8-bit Galois field inversion of the S-box using subfields of 4 bits and of 2 bits. This work describes a refinement of this approach that minimizes the circuitry, and hence the chip area, required for the S-box. While Satoh used polynomial bases at each level, we consider also normal bases, with arithmetic optimizations; altogether, 432 different cases were considered. The isomorphism bit matrices are fully optimized, improving on the "greedy algorithm." The best case reduces the number of gates in the S-box by 16%. This decrease in chip area could be important for area-limited hardware implementations, e.g., smart cards. And for applications using larger chips, this approach could allow more copies of the S-box, for parallelism and/or pipelining in non-feedback modes of AES.
