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.
