Topics in Cryptology - CT-RSA 2009: The Cryptographers' Track at the RSA Conference 2009, San Francisco,CA, USA, April 20-24, 2009, Proceedings: 5473 (Lecture Notes in Computer Science) - Softcover

This book constitutes the refereed proceedings of the Cryptographers' Track at the RSA Conference 2009, CT-RSA 2009, held in San Francisco, CA, USA in April 2009. The 31 revised full papers presented were carefully reviewed and selected from 93 submissions. The papers are organized in topical sections on identity-based encryption, protocol analysis, two-party protocols, more than signatures, collisions for hash functions, cryptanalysis, alternative encryption, privacy and anonymity, efficiency improvements, multi-party protocols, security of encryption schemes as well as countermeasures and faults.

The 2009 RSA conference was held in San Francisco, USA, during April 20-24. The conference is devoted to security-related topics and, as part of this, hosts a distinguished track for cryptographic research. Since 2001 the proceedings of this Cryptographers' Track (CT-RSA) have been published in the series Lecture Notes in Computer Science of Springer. The proceedings of CT-RSA 2009 contain 31 papers selected from 93 s- missions, covering a wide variety of cryptographic areas. Each submission was anonymizedforthereviewingprocessandwasassignedto atleastthreeofthe25 ProgramCommittee members. Submissions co-authoredby committee members were assigned to at least ?ve members. After carefully considering more than 15,000 lines (more than 100,000 words) of reviews and online discussions, the committeeselected31submissionsforacceptance. Theprogramalsoincludedan invited talk by Kenny Paterson entitled "Cryptography and Secure Channels. " Iwouldliketothankalltheauthorswhosubmittedpapers. Iamalsoindebted to the Program Committee members and all external reviewers for their vol- tary work. The committee's work was tremendously simpli?ed by Shai Halevi's submission software and his support. I would also like to thank the CT-RSA Steering Committee for electing me as Chair, and all the people from the RSA conference team for their support, especially Bree LaBollita.
