ASIACRYPT 2010 was held in the Swiss¿ otel Merchant Court in Singapore, d- ing December 5¿9, 2010. The conference was sponsored by the International Association for Cryptologic Research (IACR) in cooperation with the Coding and Cryptography Research Group of Nanyang Technological University. It was also supported by the Singapore Tourism Board, and co-sponsored by the - tional Research Foundation of Singapore, Lee Foundation, IBM Singapore Ltd., O¿Connor¿sSingaporeLtd.,Pu?ersoftLtd.,PrivylinkLtd.,Hewlett-PackardS- gaporeLtd.,JardineOneSolutionLtd.,andSingaporeMathematicalSociety.San Ling chaired the conference and I served as the Program Chair. There were 216 valid submissions. The Program Committee aided by 221 external reviewers spent 83 days on reviews and discussions. They spared no e?ort to increase the quality of their reviews. Every paper received at least three independent reviews, and papers from the committee members received ?ve reviews. In total, there were more than 730 reviews followed by intensive discussion. This long and tough process, wrapped up with an intensive face-- facemeeting by the committeemembers convenedatUCSanta Barbara,yielded 35 accepted papers. I regret not being able to select more of such high-quality papers due to space limitations. The proceedings include the revised versions of the accepted papers. The authors are fully responsible for their contents.
