Topics in cryptology

You are holding the rst in a hopefully long and successful series of RSA Cr- tographers’ Track proceedings. The Cryptographers’ Track (CT-RSA) is one of the many parallel tracks of the yearly RSA Conference. Other sessions deal with government projects, law and policy issues, freedom and privacy news, analysts’ opinions, standards, ASPs, biotech and healthcare, nance, telecom and wireless security, developers, new products, implementers, threats, RSA products, VPNs, as well as cryp- graphy and enterprise tutorials. RSA Conference 2001 is expected to continue the tradition and remain the largest computer security event ever staged: 250 vendors, 10,000 visitors and 3,000 class-going attendees are expected in San Francisco next year. I am very grateful to the 22 members of the program committee for their hard work. The program committee received 65 submissions (one of which was later withdrawn) for which review was conducted electronically; almost all papers had at least two reviews although most had three or more. Eventually, we accepted the 33 papers that appear in these proceedings. Revisions were not checked on their scienti c aspects and some authors will write nal versions of their papers for publication in refereed journals. As is usual, authors bear full scienti c and paternity responsibilities for the contents of their papers.
