Fast Software Encryption (FSE) is an annual research workshop devoted to the promotion of research on classical encryption algorithms and related cryp- graphic primitives such as hash functions. When public key cryptography started to receive wide attention in the 1980s, the much older and more basic art of secret key cryptography was sidelined at many research conferences. This motivated Ross Anderson to organise the rst FSE in Cambridge, England in December 1993; subsequent workshops followed at Leuven, Belgium (December 1994), Cambridge again (February 1996), and Haifa, Israel (January 1997). These proceedings contain the papers due to be presented at the fth FSE workshop in March 1998 at the Hotel du Louvre in Paris. This event is organized by the Ecole Normale Superieure and the Centre National pour la Recherche S- enti que (CNRS) in cooperation with the International Association for Cryp- logic Research (IACR), and has attracted the kind support of Gemplus and Microsoft, the world leaders in smart cards and software { two domains very closely connected to our research concerns.

EUROCRYEVr '97, the 15th annual EUROCRYPT conference on the theory and application of cryptographic techniques, was organized and sponsored by the International Association for Cryptologic Research (IACR). The IACR organizes two series of international conferences each year, the EUROCRYPT meeting in Europe and CRWTO in the United States. The history of EUROCRYFT started 15 years ago in Germany with the Burg Feuerstein Workshop (see Springer LNCS 149 for the proceedings). It was due to Thomas Beth's initiative and hard work that the 76 participants from 14 countries gathered in Burg Feuerstein for the first open meeting in Europe devoted to modem cryptography. I am proud to have been one of the participants and still fondly remember my first encounters with some of the celebrities in cryptography. Since those early days the conference has been held in a different location in Europe each year (Udine, Paris, Linz, Linkoping, Amsterdam, Davos, Houthalen, Aarhus, Brighton, Balantonfiired, Lofthus, Perugia, Saint-Malo, Saragossa) and it has enjoyed a steady growth, Since the second conference (Udine, 1983) the IACR has been involved, since the Paris meeting in 1984, the name EUROCRYPT has been used. For its 15th anniversary, EUROCRYPT finally returned to Germany. The scientific program for EUROCRYPT '97 was put together by a 18-member program committee whch considered 104 high-quality submissions. These proceedings contain the revised versions of the 34 papers that were accepted for presentation. In addition, there were two invited talks by Ernst Bovelander and by Gerhard Frey.

This book constitutes the refereed proceedings of the International Conference 'Cryptography: Policy and Algorithms', held in Brisbane, Queensland, Australia in July 1995.Over the past few years, issues relating to cryptography policy have made headline news, particularly those concerned with the rights to privacy of the individual, who may choose to use cryptographic systems to maintain confidentiality, against the needs of legal authorities to conduct wiretapping to help combat crime. The 27 revised full contributions in this volume are devoted to both crypto policy matters and the related theory and applications of cryptographic algorithms. The volume is of relevance to cryptology researchers and professionals in industry and administration.

Safety-related computer systems are those which may lead to loss of life, injury or plant and environmental damage. Such systems therefore have to be developed and implemented so that they meet strict require and security because their applications cover ments on safety, reliability nearly all areas of daily life and range from controlling and monitoring industrial processes, through robotics and power generation, to transport systems. Highly reliable electronic systems for safety-related applications represent an area in which industry has been involved for many years and which is now gaining increasing importance in academia. Their relevance also results from an increased perception of safety by society. Therefore, not only are technicians involved in this area, but psycho logical and sociological aspects also play a major role. Dealing with safety-related systems we have to consider the whole lifecycle of these systems, starting from specification up to implementation, assessment and operation. All those issues mentioned above are covered in this book, which represents the proceedings of the 14th International Conference on Computer Safety, Reliability and Security, SAFECOMP '95, held in Belgirate, Italy, 11-13 October 1995. The conference continues the series of SAFECOMP conferences which was originated by the European Workshop on Industrial Computer Systems, Technical Committee 7 on Safety, Security and Reliability (EWICS TC7) and reflects the state of the art, experience and new trends in the area of safety-related computer systems."
