This book constitutes the refereed proceedings of the 7th European Symposium on Research in Computer Security, ESORICS 2002, held in Zurich, Switzerland, in October 2002.The 16 revised full papers presented were carefully reviewed and selected for inclusion in the proceedings. Among the topics addressed are confidentiality, probabilistic non-inference, auctions, inference control, authentication, attacks on cryptographic hardware, privacy protection, model checking protocols, mobile code, formal security analysis, access control, and fingerprints and intrusion detection.

Some years ago, businesses could choose whether to migrate to electronic commerce, however, today it seems they have no choice. Predictions indicate that companies that do not make the necessary changes will be overrun by competition and ultimately fail. Therefore, we see more and more companies undergoing tremendous transformationin order to adapt to the new business paradigm. At the same time new companies are being established. One thing these companies have in common is the increased dependency on security technology. The invention of electronic commerce has changed the role of - curity technologies from being merely a protector to being also an enabler of electronic commerce, and it is clear that the development of security techn- ogy is a key enabler in the growth and deployment of electronic commerce. This has been recognised at European level (European Union 1997e). The launch of a comprehensive EU policy in the area of security in open networksisfairlyrecentwiththeadoptionofaCommunicationoncryptog- phy inOctober 1997(EuropeanUnion1997c). A veryimportantcomplement and support to the European policy is the European Commission s contri- tion to overcometechnological barriers by giving special importance to R&D (Research and Development) activities. The SEMPER project was launched in September 1995 and was funded partly by the European Community within the Advanced Communication Technologies and Services (ACTS) speci?c research programme part of the Fourth Framework Program (1994-1998). In this book the SEMPER project team presents in a coherent, integrated, and readable form the issues - dressed, themotivationfortheworkcarriedout, andthekeyresultsobtained. SEMPER is an innovative project in several aspects."

his book presents the refereed proceedings of the 6th European Symposium on Research in Computer Security, ESORICS 2000, held in Toulouse, France in October 2000.The 19 revised full papers presented were carefully reviewed and selected from a total of 75 submissions. The papers are organized in sections on personal devices and smart cards, electronic commerce protocols, access control, protocol verification, Internet security, security property analysis, and mobile agents.

The two volume set LNCS 12972 + 12973 constitutes the proceedings of the 26th European Symposium on Research in Computer Security, ESORICS 2021, which took place during October 4-8, 2021.The 71 full papers presented in this book were carefully reviewed and selected from 351 submissions. They were organized in topical sections as follows: Part I: network security; attacks; fuzzing; malware; user behavior and underground economy; blockchain; machine learning; automotive; anomaly detection; Part II: encryption; cryptography; privacy; differential privacy; zero knowledge; key exchange; multi-party computation.
