This book constitutes the refereed proceedings of the 18th Annual International Cryptology Conference, CRYPTO'98, held in Santa Barbara, California, USA, in August 1998. The book presents 33 revised full papers selected from a total of 144 submissions received. Also included are two invited presentations. The papers are organized in topical sections on chosen ciphertext security, cryptanalysis of hash functions and block ciphers, distributed cryptography, zero knowledge, and implementation.

This text presents the proceedings of an international conference on advances in cryptology. The papers are organized into topical sections on chosen ciphertext security, cryptanalysis of hash functions and block ciphers, distributed cryptography, zero knowledge and implementation.

Crypto ’99, the Nineteenth Annual Crypto Conference, was sponsored by the International Association for Cryptologic Research (IACR), in cooperation with the IEEE Computer Society Technical Committee on Security and Privacy and the Computer Science Department, University of California, Santa Barbara (UCSB). The General Chair, Donald Beaver, was responsible for local organization and registration. The Program Committee considered 167 papers and selected 38 for presentation. This year’s conference program also included two invited lectures. I was pleased to include in the program UeliM aurer’s presentation “Information Theoretic Cryptography” and Martin Hellman’s presentation “The Evolution of Public Key Cryptography.” The program also incorporated the traditional Rump Session for informal short presentations of new results, run by Stuart Haber. These proceedings include the revised versions of the 38 papers accepted by the Program Committee. These papers were selected from all the submissions to the conference based on originality, quality, and relevance to the field of cryptology. Revisions were not checked, and the authors bear full responsibility for the contents of their papers.

ASIACRYPT’98, the international conference covering all aspects of theory and application of cryptology and information security, is being held at Beijing Friendship Hotel from October 18 to 22. This is the fourth of the Asiacrypt conferences. ASIACRYPT’98 is sponsored by the State Key Laboratory of Information Security (SKLOIS), University of Science and Technology of China (USTC), and the Asiacrypt Steering Committee (ASC), in cooperation with the International Association for Cryptology Research (IACR). The 16-member Program Committee organized the scientific program and considered 118 submissions. Of these, 32 were accepted for presentation. The authors’ affiliations of the 118 submissions and the 32 accepted papers range over 18 and 13 countries or regions, respectively. The submitted version of each paper was sent to all members of the Program Committee and was extensively examined by at least three committee members and/or outside experts. The review process was rigorously blinded and the anonymity of each submission are maintained until the selection was completed. We followed the traditional policy that each member of the Program Committee could be an author of at most one accepted paper. These proceedings contain the revised versions of the 32 contributed talks as well as a short note written by one invited speaker. Comments from the Program Committee were taken into account in the revisions. However, the authors (not the committee) bear full responsibility for the contents of their papers.

This book constitutes the refereed proceedings of the 23rd Annual International Cryptology Conference, CRYPTO 2003, held in Santa Barbara, California in August 2003. The 34 revised full papers presented together with 2 invited papers were carefully reviewed and selected from 166 submissions. The papers are organized in topical sections on public key cryptanalysis, alternate adversary models, protocols, symmetric key cryptanalysis, universal composability, zero knowledge, algebraic geometry, public key constructions, new problems, symmetric key constructions, and new models.

Crypto '91 was the eleventh in a series of workshops on cryptology sponsoredby the International Association for Cryptologic Research and was held in Santa Barbara, California, in August 1991. This volume contains a full paper or an extended abstract for each of the 39 talks presented at the workshop. All theoretical and practical aspects of cryptology are represented, including: protocol design and analysis, combinatorics and authentication, secret sharing and information theory, cryptanalysis, complexity theory, cryptographic schemas based on number theory, pseudorandomness, applications and implementations, viruses, public-key cryptosystems, and digital signatures.
