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 1970`s, 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 modified versions of DES. The methodology used offers valuable insights to anyone interested in data security and cryptography, and points out the intricacies of developing, evaluating, testing, and implementing such schemes. This book was written by two of the field`s leading researchers, and describes state-of-the-art research in a clear and completely contained manner.

These are the proceedings of EUROCRYPT 2003, the 22nd annual EURO- CRYPT conference. The conference was sponsored by the IACR, the Internat- nal Association for Cryptologic Research,www.iacr.org, this year in coope- tion with the Institute of Mathematics and Cryptology, Faculty of Cybernetics, Military University of Technology, Warsaw, Poland. The General Chair, Jerzy Gawinecki, was responsible for the local organization, and the conference re- stration was handled by the IACR secretariat at the University of California, Santa Barbara, USA. A total of 37 papers were accepted for presentation at the conference, out of 156 papers submitted (of which one was withdrawn by the authors shortly after the submission deadline). These proceedings contain revised versions of the accepted papers. In addition two invited talks were given: the ?rst was given by Kris Gaj and Arkadiusz Orlowski, entitled "Facts and Myths of Enigma: Breaking Stereotypes." The second invited talk was given by Jacques Stern - titled "Why Provable Security Matters?" The conference program also included arumpsession,chairedbyStanis lawJarecki,whichfeaturedshortinformaltalks on recent results.

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 cryptography.
