An Introduction to Cryptography--Second Edition


From the Preface: * Includes items of contemporary interest, such as electronic mail and Internet security, as well as cutting-edge applications, including network security, biometrics, and smart cards *Discusses symmetric and public-key cryptosystems, the digital signature standard, and DES (via S-DES) *Covers Internet security issues, including identity theft, fraud, and financial data theft *Examines the human side of cryptography with nearly sixty mini-biographies. Continuing a bestselling tradition, An Introduction to Cryptography, Second Edition provides a solid foundation in cryptographic concepts that features all of the requisite background material on number theory and algorithmic complexity as well as a historical look at the field. With numerous additions and restructured material, this edition presents the ideas behind cryptography and the applications of the subject. The first chapter provides a thorough treatment of the mathematics necessary to understand cryptography, including number theory and complexity, while the second chapter discusses cryptographic fundamentals, such as ciphers, linear feedback shift registers, modes of operation, and attacks. The next several chapters discuss DES, AES, public-key cryptography, primality testing, and various factoring methods, from classical to elliptical curves. The final chapters are comprised of issues pertaining to the Internet, such as pretty good privacy (PGP), protocol layers, firewalls, and cookies. As well, it includes applications such as login and network security, viruses, smart cards, and biometrics. The book concludes with appendices on mathematical data, computer arithmetic, the Rijndael S-Box, knapsack ciphers, the Silver-Pohlig-Hellman algorithm, the SHA-1 algorithm, radix-64 encoding, and quantum cryptography.
