• Represents a major revision and updating of the bestselling first edition
• Includes a new chapter on block ciphers and the new advanced encryption standard (AES) and another on the applications of secret sharing schemes
• Adds new material on elliptic curve DSA and the Random Oracle Model, generic algorithms for the discrete logarithm problem, and the Dillard rho algorithm
• Serves as an outstanding text for a first course in cryptography for students of computer science and mathematics

The Advanced Encryption Standard (AES), elliptic curve DSA, the secure hash algorithm...these and other major advances over that last five years demanded this comprehensive revision of the standard-setting text and reference, Cryptography: Theory and Practice. Now more tightly focused on the core areas, it contains many new topics as well as thoroughly updated treatments of topics presented in the first edition. There is increased emphasis on general concepts, but the outstanding features that first made this a bestseller all remain, including its mathematical rigor, numerous examples, pseudocode descriptions of algorithms, and clear, precise explanations.

New in the Second Edition:

• Explains the latest Federal Information Processing Standards , including the Advanced Encryption Standard (AES), the Secure Has Algorithm (SHA-1), and the Elliptic Curve Digital Signature Algorithm (ECDSA)
• Uses substitution-permutation networks to introduce block cipher design and analysis concepts
• Explains both linear and differential cryptanalysis
• Presents the Random Oracle model for hash functions
• Addresses semantic security of RSA and Optional Asymmetric Encryption Padding
• Discusses Wiener's attach on low decryption exponent RSA

Overwhelmingly popular and relied upon in its first edition, now, more than ever, Cryptography: Theory and Practice provides an introduction to the field ideal for upper-level students in both mathematics and computer science.

More highlights of the Second Edition:

• Provably secure signature schemes: Full Domain Hash
• Universal hash families
• Expanded treatment of message authentication codes
• More discussions on elliptic curves
• Lower bounds for the complexity of generic algorithms for the discrete logarithm problem
• Expanded treatment of factoring algorithms
• Security definitions for signature schemes
