Selected Areas in Cryptography

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 Atotalof41papersweresubmittedtoSAC2000,oneofwhichwassubsequently withdrawn.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. Many thanks are due to the p- gramcommitteefortheirhardwork.Also,AmrYoussefprovidedgreatassistance in making the reviewing process run smoothly.
