International Association for Cryptologic Research

Preface, IACR PKC 2007

The 10th International Conference on Theory and Practice of Public-Key Cryptography (PKC 2007) was held at Tsinghua University in Beijing, China, April 16--20, 2007. PKC is the premier international conference dedicated to cryptology focusing on all aspects of public-key cryptography. The event is sponsored by the International Association of Cryptologic Research (IACR), and this year it was also sponsored by National Natural Science Foundation of China (NSFC) and Tsinghua University.

The conference received 118 submissions, and the program committee selected 29 of these for presentation. The program committee worked very hard to evaluate the papers with respect to quality, originality, and relevance to public-key cryptography. Each paper was anonymously reviewed by at least three program committee members.

Extended abstracts of the revised versions of the accepted papers are in these proceedings. The program also included three invited lectures by Rafail Ostrovsky with UCLA, USA, Shige Peng with Shandong University, China and Adi Shamir with the Weizmann Institute of Science, Israel. Two papers regarding the invited lectures are included in these proceedings. The PKC 2007 program committee had the pleasure of according this year's PKC best paper award to Xavier Boyen and Brent Waters for their paper, entitled "Full-Domain Subgroup Hiding and Constant-Size Group Signatures."

We are extremely grateful to the program committee members for their enormous investment of time and effort in the difficult and delicate process of review and selection. We gratefully acknowledge the help of a large number of external reviewers who reviewed submissions in their area of expertise. We also thank the PKC steering committee for their support.

Electronic submissions were made possible by the Web Review system, iChair, developed by Thomas Baign{é}res and Matthieu Finiasz at EPFL, LASEC. We would like to thank Thomas Baign{é}res and Matthieu Finiasz for their great supports.

We deeply thank Andrew C. Yao, the General Chair, for his efforts to organize and make this conference possible. The respect and centripetal force to the great scientist was the source of the success of PKC 2007.

We are grateful to all the organization committee members for their volunteer work. In addition, we would like to thank Wei Yu for his enormous support in installing and operating the iChair system in the review process and editing these proceedings.

We wish to thank all the authors, in submitting papers, and the authors of accepted papers for their cooperation.
