Advances In Cryptology Eurocrypt 95

This volume constitutes the proceedings of EUROCRYPT '95, the 1995 International Workshop on the Theory and Application of Cryptographic Techniques, held in Saint-Malo, France in May 1995 under the sponsorship of the International Association for Cryptologic Research (IACR). The volume contains revised versions of the 33 papers selected from a total of 113 submissions. All current aspects of cryptologic research and advanced applications are addressed; there are sections on cryptanalysis, signatures, computational number theory, cryptographic protocols, secret sharing, electronic cash, shift registers and Boolean functions, authentication codes, new schemes, complexity aspects, and implementation aspects.

This volume is concerned with the individual steps in the pathway of retrovirus morphogenesis and maturation starting at the point where the components of the virion have been synthesized within the infected cell and ending once the infectious virion has been released from this cell. An introductory chapter provides a comparative description of the structure and morphology of infectious viruses. A novel feature is the organization according to individual steps in the pathway of virus particle formation rather than according to individual viruses or virus groups as has been done in most previous reviews. This novel concept should allow a comparative discussion of the similarities and differences within this complex virus family regarding the specific aspects of formation of an infectious virion.

The Crypto ’95 conference was sponsored by the International Association for Cryptologic Research (IACR), in cooperation with the IEEE Computer - ciety Technical Committee on Security and Privacy, and the Computer Science Department of the University of California, Santa Barbara. It took place at the University of California, Santa Barbara, from August 27-31, 1995. This was the fifteenth annual Crypto conference; all have been held at UCSB. For the second time, proceedings were available at the conference. The General Chair, Stafford Tavares, was responsible for local organization and registration. The Program Committee considered 151 papers and selected 36 for pres- tation. There were also two invited talks. Robert Morris, Sr. gave a talk on “Ways of Losing Information,” which included some non-cryptographic means of leaking secrets that are often overlooked by cryptographers. The second talk, “Cryptography - Myths and Realities,” was given by Adi Shamir, this year’s IACR Distinguished Lecturer. Shamir is the second person to receive this honor, the first having been Gus Simmons at Crypto ’94. These proceedings contain revised versions of the 36 contributed talks. Each paper was sent to at least three members of the program committee for c- ments. Revisions were not checked on their scientific aspects. Some authors will write final versions of their papers for publication in refereed journals. Of course, the authors bear full responsibility for the contents of their papers.

The EUROCRYPT ’96 conference was sponsored by the International Asso- ation for Cryptologic Research (IACR)l, in cooperation with the University of Saragossa. It took place at the Palacio de Congresos in Saragossa, Spain, during May 12-16, 1996. This was the fifteenth annual EUROCRYPT conference (this name has been used since the third conference held in 1984), each of which has been held in a different city in Europe. For the second time, proceedings were available at the conference. JosC Pastor Franco, the General Chair, was resp- sible for local organization and registration. His contribution to the snccess of the conference is gratefully acknowledged. The Program Committee considered 126 submitted papers and selected 34 for presentation. Each paper was sent to all members of the Program Committee and was assigned to at least three of them for careful evaluation. There were also two invited talks. James L. Massey, this year’s IACR Distinguished Ltcturer, gave a lecture entitled “The difficulty with difficulty”. Massey is the third to receive this honor, the first two being Gustavus Simmons and Adi Shamir. Shafi Goldwasser gave an invited talk entitled “Multi party secure protocols: past and present”. These proceedings contain revised versions of the 34 contributed talks. While the papers were carefully selected, they have not been refereed like submissions to a refereed journal. The authors bear full responsibility for the contents of their papers. Some authors may write final versions of their papers for publication in a refereed journal.

Cryptography, in particular public-key cryptography, has emerged in the last 20 years as an important discipline that is not only the subject of an enormous amount of research, but provides the foundation for information security in many applications. Standards are emerging to meet the demands for cryptographic protection in most areas of data communications. Public-key cryptographic techniques are now in widespread use, especially in the financial services industry, in the public sector, and by individuals for their personal privacy, such as in electronic mail. This Handbook will serve as a valuable reference for the novice as well as for the expert who needs a wider scope of coverage within the area of cryptography. It is a necessary and timely guide for professionals who practice the art of cryptography. The Handbook of Applied Cryptography provides a treatment that is multifunctional: It serves as an introduction to the more practical aspects of both conventional and public-key cryptography It is a valuable source of the latest techniques and algorithms for the serious practitioner It provides an integrated treatment of the field, while still presenting each major topic as a self-contained unit It provides a mathematical treatment to accompany practical discussions It contains enough abstraction to be a valuable reference for theoreticians while containing enough detail to actually allow implementation of the algorithms discussed Now in its third printing, this is the definitive cryptography reference that the novice as well as experienced developers, designers, researchers, engineers, computer scientists, and mathematicians alike will use.

This book constitutes the thoroughly refereed post-workshop proceedings of the 6th International Workshop on Fast Software Encryption, FSE'99, held in Rome, Italy, in March 1999. The 22 revised full papers presented were carefully selected from a total of 51 submissions during two rounds of reviewing and revision. The volume is divided into sections on advanced encryption standard (AES), remotely keyed encryptions, analysis of block ciphers, miscellaneous, modes of operation, and stream ciphers.
