CRYPTO2010 the30thAnnualInternationalCryptologyConference wassp- sored by the International
Association for Cryptologic Research (IACR) in - operation with the IEEE Computer Society
Technical Committee on Security and Privacy and the Computer Science Department of the
University of C- ifornia at Santa Barbara. The conference was held in Santa Barbara Calif- nia
during August 15-19 2010 in conjunction with CHES 2010 (Workshop on Cryptographic Hardware
and Embedded Systems). Zul?kar Ramzan served as the General Chair. The conference received 203
submissions. The quality of the submissions was very high and the selection process was a
challenging one. The Program C- mittee aided by a 159 external reviewers reviewed the
submissions and after an intensive review period the committee accepted 41 of these
submissions. Three submissions were merged into a single paper and two papers were merged into
a single talk yielding a total of 39 papers in the proceedings and 38 presen- tions at the
conference. The revised versions of the 39 papers appearing in the proceedings were not subject
to editorial review and the authors bear full - sponsibility for their contents. The best-paper
award was awarded to the paper Toward Basing Fully Homomorphic Encryption on Worst-Case
Hardness by Craig Gentry. The conference featured two invited presentations. This year we
celebrated 25 years from the publication of the ground-breaking work of Sha? Goldwasser Silvio
Micali and Charles Racko? The Knowledge Complexity of Interactive Proof-Systems.
