Theory of Cryptography 7th Theory of Cryptography Conference, TCC 2010, Zurich, Switzerland, February 9-11, 2010, Proceedings

TCC2010,the7thTheoryofCryptographyConference,washeldatETHZurich, Zurich, Switzerland, during February 9–11, 2010. TCC 2010 was sponsored by theInternationalAssociationofCryptologicResearch(IACR)andwasorganized in cooperation with the Information Security and Cryptography group at ETH Zurich.The GeneralChairsof the conferencewereMartin Hirt andUeli Maurer. The conference received 100 submissions, of which the Program Committee selected 33 for presentation at the conference. The Best Student Paper Award was given to Kai-Min Chung and Feng-Hao Liu for their paper “ParallelRepe- tion Theorems for Interactive Arguments.” These proceedings consist of revised versions of those 33 papers. The revisions were not reviewed, and the authors bearfull responsibility forthe contentsoftheir papers.Inadditionto the regular papers, the conference featured two invited talks: “Secure Computation and Its Diverse Applications,” given by Yuval Ishai and “Privacy-Enhancing Crypt- raphy: From Theory Into Practice,” given by Jan Camenisch. Abstracts of the invited talks are also included in this volume. As in previous years, TCC received a steady stream of high-quality s- missions. Consequently, the selection process was very rewarding, but also very challenging, as a number of good papers could not be accepted due to lack of space. I would like to thank the TCC Steering Committee, and its Chair Oded Goldreich, for entrusting me with the responsibility of selecting the conference program.Since its inception, TCChas been verysuccessfulin attracting someof the best work in theoretical cryptography every year and o?ering a compelling program to its audience. I am honored I had the opportunity to contribute to the continuation of the success of the conference.
