This book constitutes the refereed proceedings of the International Conference on the Theory and Applications of Cryptographic Techniques, EUROCRYPT 2003, held in Warsaw, Poland in May 2003. carefully reviewed and selected from 156 submissions. multi-party communication, zero-knowledge protocols, foundations and complexity-theoretic security, public key encryption, new primitives, elliptic curve cryptography, digital signatures, information-theoretic cryptography, and group signatures.

This volume constitutes the strictly refereed post-workshop proceedings of the Fourth International Workshop on Fast Software Encryption, FSE'97, held in Haifa, Israel, in January 1997.
The 23 full papers presented were carefully selected from 44 submissions and revised for inclusion in the book. Also contained is a summary of a panel discussion. The papers are organized in sections on cryptanalysis, blockciphers, stream ciphers, message authentication codes, modes of operation, and fast software encryption. Particular emphasis is placed on applicability and implementation issues of fast...

DES, the Data Encryption Standard, is the best known and most widely used civilian cryptosystem. It was developed by IBM and adopted as a US national standard in the mid 1970s, and had resisted all attacks in the last 15 years. This book presents the first successful attack which can break the full 16 round DES faster than via exhaustive search. It describes in full detail, the novel technique of Differential Cryptanalysis, and demonstrates its applicability to a wide variety of cryptosystems and hash functions, including FEAL, Khafre, REDOC-II, LOKI, Lucifer, Snefru, N-Hash, and many...
