These thanks are of course extended to the very many external reviewers who took the time to help out during the evaluation process.It was also a greatpleasure to honor and welcome Moti Yung who gave the 2010 IACR Distinguished Lecture.

The RSA Conference is the largest regularly-staged computer security event, with over 350 vendors and many thousands of attendees. The Cryptographers'Track (CT-RSA) is a research conference within the RSA Conference. CT-RSA began in 2001, and has become one of the major established venues for presenting cryptographic research papers to a wide variety of audiences. CT-RSA 2008 was held in San Francisco, California from April 8 to April 11. The proceedings of CT-RSA 2008 contain 26 papers selected from 95 subm- sions pertaining to all aspects of cryptography. Each submission was reviewed by at least three reviewers, which was made possible by the hard work of 27 P- gram Committee members and many external reviewers listed on the following pages. The papers were selected following a detailed online discussion among the Program Committee members. The program included an invited talk by Sha? Goldwasser. The current proceedings include a short abstract of her talk. I would like to express my deep gratitude to the Program Committee m- bers, who volunteered their expertise and hard work over several months, as well as to the external reviewers. Special thanks to Shai Halevi for providing and maintaining the Web review system used for paper submission, reviewing, and?nal-version preparation. Finally, I would like to thank Burt Kaliski and Ari Juels of RSA Laboratories, as well as the RSA conference team, especially Bree LaBollita, for their assistance throughout the process.

In this proceedings volume you will?nd the revised versions of the 39 papers that were presented at the conference. The submissions represent the current state of work in the cryptographic community worldwide, covering all areas of cryptologic research. In fact, many high-quality works (that surely will be published elsewhere) could not be accepted. This is due to the competitive nature of the conference and the challenging task of selecting a program. I wish to thank the authors of all submitted papers. Indeed, it is the authors of all papers who have made this conference possible, regardless of whether or not their papers were accepted. The conference program was also immensely bene?ted by two plenary talks.
