Résumé

Nigel Smart's Cryptography: An Introduction 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.Incorporating practical examples and real-world case studies, Nigel Smart examines 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.ContentsPart I Mathematical Background
