This volume presents the proceedings of the second European Symposium on Research in Computer Security (ESORICS 92), held in Toulouse in November 1992. The aim of this symposium is to further the progress of research in computer security by bringing together researchers in this area, by promoting the exchange of ideas with system developers, and by encouraging links with researchers in areas related to computer science, informationtheory, and artificial intelligence. The volume contains 24 papers organizedinto sections on access control, formal methods, authentication, distributed systems, database security, system architectures, and applications. ESORICS 92 was organized by AFCET (Association francaise des sciences et technologies de l'information et des syst mes) in cooperation with a large number of national and international societies and institutes.
