Cryptography : an introduction

Nigel Smarts Cryptography provides the rigorous detail required for advanced cryptographic studies, yet approaches the subject matter in an accessible style in order to gently guide new students through difficult mathematical topics. Covering the latest developments in computer cryptography, including the Rijndael algorithm chosen for the new Advanced Encryption Standard, the OAEP padding system for RSA and modern stream ciphers, this book is a complete introduction to cryptography. Cryptography incorporates practical examples and real-world case studies to examine strategies for security in multiple languages and various contexts. The author gives specific focus to implementation issues such as exponentiation in DSA and RSA, and to provably secure algorithms with and without random oracles. Cryptography is fully supported by an Online Learning Centre. This includes lecture slides, sample software in different source languages, further exercises and a complete solutions guide for the book. Also included is a wide resource of links to key cryptographic sites and data sources from around the world.
