This book constitutes the refereed proceedings of the 11th International Conference on the Theory and Application of Cryptology and Information Security, ASIACRYPT 2005, held in Chennai, India in December 2005. The 37 revised full papers presented were carefully reviewed and selected from 237 submissions. The papers are organized in topical sections on algebra and number theory, multiparty computation, zero knowledge and secret sharing, information and quantum theory, privacy and anonymity, cryptanalytic techniques, stream cipher cryptanalysis, block ciphers and hash functions, bilinear maps, key agreement, provable security, and digital signatures.

Constitutes the refereed proceedings of the 12th International Conference on the Theory and Application of Cryptology and Information Security. This book presents papers on attacks on hash functions, stream ciphers and boolean functions, biometrics and ECC computation, id-based schemes, public-key schemes, RSA and factorization, and more.

The 10th Annual ASIACRYPT 2004 was held in Jeju Island, Korea, d- ing December 5–9, 2004. This conference was organized by the International Association for Cryptologic Research (IACR) in cooperation with KIISC (- rean Institute of Information Security and Cryptology) and IRIS (International Research center for Information Security) at ICU (Information and Communi- tionsUniversity),andwas?nanciallysupportedbyMIC(MinistryofInformation and Communication) in Korea. The conference received, from 30 countries, 208 submissions that represent the current state of work in the cryptographic community worldwide, covering all areas of cryptologic research. Each paper, without the authors’ information, was reviewed by at least three members of the program committee, and the papers (co-)authored by members of the program committee were reviewed by at least six members. We also blinded the reviewers’ names among the reviewers until the ?nal decision, by using pseudonyms. The reviews were then followed by deep discussions on the papers, which greatly contributed to the quality of the ?nal selection. In most cases, extensive comments were sent to the authors. Among 208 submissions, the program committee selected 36 papers. Two submissions were merged into a single paper, yielding the total of 35 papers acceptedforpresentationinthetechnicalprogramoftheconference.Manyhi- quality works could not be accepted because of the competitive nature of the conference and the challenging task of selecting a program. These proceedings contain revised versions of the accepted papers. These revisions have not been checked for correctness, and the authors bear full responsibility for the contents of their papers.

This book constitutes the refereed proceedings of the 13th International Conference on the Theory and Application of Cryptology and Information Security, ASIACRYPT 2007, held in Kuching, Malaysia, in December 2007. The papers are organized in topical sections on number theory and elliptic curve, protocol, hash function design, group/broadcast cryptography, mac and implementation, multiparty computation, block ciphers, foundation, public key encryption, and cryptanalysis.
