ICICS 2001, the Third International Conference on Information and Commu- cations Security, was held in Xi'an, China, 13-16 November 2001. Among the preceding conferences, ICICS'97 was held in Beijing, China, 11-14 November 1997 and ICICS'99 in Sydney, Australia, 9-11 November 1999. The ICICS'97 and ICICS'99 proceedings were released as volumes 1334 and 1726 of Springer- Verlag's Lecture Notes in Computer Science series. ICICS 2001 was sponsored by the Chinese Academy of Sciences (CAS), the - tional Natural Science Foundation of China, and the China Computer Fe- ration. The conference was organized by the Engineering Research Center for Information Security Technology of the Chinese Academy of Sciences (ERCIST, CAS) in co-operation with the International Association for Cryptologic Re- arch (IACR), the International Communications and Information Security - sociation (ICISA), and the Asiacrypt Steering Committee. The format of ICICS 2001 was selected to cover the complete spectrum of - formation and communications security, and to promote participant interaction. The sessions were designed to promote interaction between the major topics of the conference: theoretical foundations of security, secret sharing, network - curity, authentication and identi?cation, boolean functions and stream ciphers, security evaluation, signatures, block ciphers and public-key systems, infor- tion hiding, protocols and their analysis, and cryptanalysis. The 29-member Program Committee considered 134 submissions from 23 di- rent countries and regions, among them 56 papers were accepted for presentation.

Pairing-based cryptography is at the very leading edge of the current wave in computer cryptography. That makes this book all the more relevant, being as it is the refereed proceedings of the First International Conference on Pairing-Based Cryptography, Pairing 2007, held in Tokyo, Japan in 2007. The 18 revised full papers presented together were carefully reviewed and selected from 86 submissions. The papers are organized in topical sections including those on applications, and certificateless public key encryption.

This book constitutes the refereed proceedings of the 10th International Conference on Practice and Theory in Public-Key Cryptography, PKC 2007, held in Beijing, China in April 2007.The 29 revised full papers presented together with two invited lectures are organized in topical sections on signatures, cryptanalysis, protocols, multivariate cryptosystems, encryption, number theoretic techniques, and public-key infrastructure.

The Cryptographers' Track (CT-RSA) is a research conference within the RSA conference, the largest, regularly staged computer security event. CT-RSA 2004 was the fourth year of the Cryptographers' Track, and it is now an established venue for presenting practical research results related to cryptography and data security. The conference received 77 submissions, and the program committee sel- ted 28 of these for presentation. The program committee worked very hard to evaluate the papers with respect to quality, originality, and relevance to cryp- graphy. Each paper was reviewed by at least three program committee members. Extended abstracts of the revised versions of these papers are in these proc- dings. The program also included two invited lectures by Dan Boneh and Silvio Micali. I am extremely grateful to the program committee members for their en- mous investment of time and e?ort in the di?cult and delicate process of review and selection. Many of them attended the program committee meeting during the Crypto 2003 conference at the University of California, Santa Barbara.

ASIACRYPT 2000 was the sixth annual ASIACRYPT conference. It was sp- sored by the International Association for Cryptologic Research (IACR) in - operation with the Institute of Electronics, Information, and Communication Engineers (IEICE). The ?rst conference with the name ASIACRYPT took place in 1991, and the series of ASIACRYPT conferences were held in 1994, 1996, 1998, and 1999, in cooperation with IACR. ASIACRYPT 2000 was the ?rst conference in the series to be sponsored by IACR. The conference received 140 submissions (1 submission was withdrawn by the authors later), and the program committee selected 45 of these for presen- tion. Extended abstracts of the revised versions of these papers are included in these proceedings. The program also included two invited lectures by Thomas Berson (Cryptography Everywhere: IACR Distinguished Lecture) and Hideki Imai (CRYPTREC Project - Cryptographic Evaluation Project for the Japanese Electronic Government). Abstracts of these talks are included in these proce- ings. The conference program also included its traditional "e;rump session"e; of short, informal or impromptu presentations, kindly chaired by Moti Yung. Those p- sentations are not re?ected in these proceedings. The selection of the program was a challenging task as many high quality submissions were received. The program committee worked very hard to evaluate the papers with respect to quality, originality, and relevance to cryptography. I am extremely grateful to the program committee members for their en- mous investment of time and e?ort in the di?cult and delicate process of review and selection.
