ASIACRYPT 2007 was held in Kuching, Sarawak, Malaysia, during December 2-6, 2007. This was the 13th ASIACRYPT conference, and was sponsored by the International Association for Cryptologic Research (IACR), in cooperation with the Information Security Research (iSECURES) Lab of Swinburne University of Technology (Sarawak Campus) and the Sarawak Development Institute (SDI), and was ?nancially supported by the Sarawak Government. The General Chair was Raphael Phan and I had the privilege of serving as the Program Chair. The conference received 223 submissions (from which one submission was withdrawn). Each paper was reviewed by at least three members of the Program Committee, while submissions co-authored by a Program Committee member were reviewed by at least ?ve members. (Each PC member could submit at most one paper.) Many high-quality papers were submitted, but due to the relatively small number which could be accepted, many very good papers had to be rejected. After 11 weeks of reviewing, the Program Committee selected 33 papers for presentation (two papers were merged). The proceedings contain the revised versions of the accepted papers. These revised papers were not subject to editorial review and the authors bear full responsibility for their contents.
