Selected Areas in Cryptography: 7th Annual International Workshop, SAC 2000, Waterloo, Ontario, Canada, August 14-15, 2000. Proceedings (Lecture Notes in Computer Science, 2012)

SAC 2000 was the seventh in a series of annual workshops on Selected Areas in Cryptography.PreviousworkshopswereheldatQueen'sUniversityinKingston (1994, 1996, 1998, and 1999) and at Carleton University in Ottawa (1995 and 1997). The intent of the workshops is to provide a relaxed atmosphere in which researchers in cryptography can present and discuss new work on selected areas of current interest. The themes for the SAC 2000 workshop were: - design and analysis of symmetric key cryptosystems, - primitivesforprivatekeycryptography, includingblockandstreamciphers, hash functions, and MACs, - e?cientimplementationsofcryptographicsystemsinpublicandprivatekey cryptography, - cryptographic solutions for web/internet security. Atotalof41papersweresubmittedtoSAC2000, oneofwhichwassubsequently withdrawn. After a review process that had all papers reviewed by at least 3 referees, 24 papers were accepted for presentation at the workshop. As well, we were fortunate to have the following two invited speakers at SAC 2000: - M. Bellare, UCSD (U.S.A.) "The Provable-Security Approach to Authenticated Session-Key Exchange" - D. Boneh, Stanford U. (U.S.A.) "Message Authentication in a Multicast Environment" The program committee for SAC 2000 consisted of the following members: L. Chen, H. Heys, L. Knudsen, S. Moriai, L. O'Connor, D. Stinson, S. Tavares, S. Vaudenay, A. Youssef, and R. Zuccherato.

This book constitutes the thoroughly refereed post-proceedings of the 7th Annual International Workshop on Selected Areas in Cryptography, SAC 2000, held in Waterloo, Ontario, Canada, in August 2000.
The 24 revised full papers presented were selected from 41 submissions and have gone through two rounds of reviewing and revision. The papers are organized in topical sections on cryptanalysis, block ciphers: new designs, elliptic curves and efficient implementations, security protocols and applications, block ciphers and hash functions, Boolean functions and stream ciphers, and public key systems.
