Topics in Cryptology -- CT-RSA 2006 e-bog

The RSA R Conference, with over 15,000attendees, as well as over 225 sponsors and exhibitors, is the largest computer security event of the year. The Cr- tographers' Track is one of the many parallel tracks. These proceedings contain the papers presented during the sixth edition. The tradition indeed started in 2001, and is by now well established: the Cryptographers' Track at the RSA Conference is among the major events in cryptography. There were 72 submitted contributions, of which 22 were selected for p- sentation. They cover all aspects of cryptography (symmetric and asymmetric cryptography, constructions and attacks, new trends). In addition, the program includes two invited talks, by Xiaoyun Wang on "e;Cryptanalysis of Hash fu- tions and Potential Dangers,"e; and Philip MacKenzie on "e;Passwords Will Not Die: How Cryptography Can Help Deal with Them. "e; All the submissions were reviewed by at least three members of the Program Committee. Iamverygratefultothe24membersfortheirhardandconscientious work.
