"Tutorial on Message Authentication Codes" | | Abstract: Authenticity is more important than secrecy because the former is always required while the latter is not. This talk first shows a model and a construction of unconditionally secure Authentication codes (A-codes). The size of keys can be much shorter than the size of messages. It next shows how to extend an A-code to a computationally secure Message Authentication Code (MAC). Finally, HMAC and CBC-MAC family are presented briefly.
Biographical Sketch: Kaoru Kurosawa the M.E. and Ph.D. degrees in electrical engineering at Tokyo Institute of Technology in 1979 and 1982, respectively. At Tokyo Institute of Technology, he became a research associate in 1982, a lecturer in 1985, an associate professor in 1989, and a professor in 1997. He moved to Ibaraki University in 2001. He received Best paper award of IEICE in 1981, Young engineer award of IEICE in 1986 Telecom-System Scientific Award of Telecommunications Advancement Foundation in 2006 and Achievement award of IEICE in 2007. He has been working on cryptography since 1985. He is an associate editor of five journals including IET Information Security. He was Program co-Chair of ACM DRM workshop 2006, and is now Program Chair of Asiacrypt 2007. He is also Vice Chair of IEEE Tokyo Section Nominations Committee in 2007. He is a co-developer of CMAC authentication algorithm which is a NIST recommendation for modes, Special Publication 800-38B.
