Cryptography: Theory and Practice (Third edition) Douglas R. Stinson The Legacy… First introduced in 1995, Cryptography: Theory and Practice garnered enormous praise and popularity, and soon became the standard textbook for cryptography courses around the world. The second edition was equally embraced, and both editions enjoy status as perennial bestsellers. Now in its third edition, this authoritative text continues to provide a solid foundation for future breakthrough in cryptography. Why a Third Edition? The art and science of cryptography has been evolving for thousands of years. Now, with unprecedented amounts of information circling the globe, we must be prepared to face new threats and employ new encryption schemes on an ongoing basis. This edition updates relevant chapters with the latest advances and includes chapters covering: * Pseudo-random bit generation in cryptography * Entity authentication, including schemes built from primitives and special purpose "zero-knowledge" schemes. * Key establishment including key distribution and protocols for key agreement, both with a greater emphasis on security models and proofs. * Public-key infrastructure, including identity-based cryptography * Secret sharing schemes * Multicast security, including broadcast encryption and copyright protection. The result… Providing mathematical background in a "just-in-time" fashion, informal descriptions of cryptosystems along with more precise pseudo-code, and a host of numerical examples and exercises, Cryptography: Theory and Practice, Third Edition offers comprehensive, in-depth treatment of the methods and protocols needed to safeguard the mind-boggling amount of information circulating around the world. Douglas R. Stinson is Professor and University Research Chair at the School of Computer Science, University of Waterloo, Ontario, Canada.
