These are the proceedings of Crypto 2005, the 25th Annual International Cr- tology Conference. The conference was sponsored by the International Assoc- tion for Cryptologic Research (IACR) in cooperation with the IEEE Computer ScienceTechnicalCommitteeonSecurityandPrivacyandtheComputerScience DepartmentoftheUniversityofCaliforniaatSantaBarbara.Theconferencewas held in Santa Barbara, California, August 14 18, 2005. Theconferencereceived178submissions,outofwhichtheprogramcommittee selected33forpresentation.Theselectionprocesswascarriedoutbytheprogram committee via an online meeting. The authors of selected papers had a few weeks to prepare ?nal versions of their papers, aided by comments from the reviewers. However, most of these revisions were not subject to any editorial review. This year, a Best Paper Award was given to Xiaoyun Wang, Yiqun Lisa Yin, and Hongbo Yu, for their paper Finding Collisions in the Full SHA-1. The conference program included two invited lectures. Ralph Merkle del- ered an IACR Distinguished Lecture, entitled The Development of Public Key Cryptography:a PersonalView; and Thoughts on Nanotechnology. Dan Boneh gave an invited talk, entitled Bilinear Maps in Cryptography. We continued the tradition of a rump session, featuring short, informal presentations (usually serious, sometimes entertaining, and occasionally both). The rump session was chaired this year by Phong Q. Nguy en.
