NORDSEC 2000, October 12-13, 2000, Reykjavik, Iceland The Fifth Nordic Workshop on Secure IT Systems - Encouraging Co-operation (Submissions due: August 1, 2000) The NORDSEC workshops were started in 1996 with the aim to bring together researchers and practitioners within IT security in the Nordic countries. These workshops have remained a forum for co-operation between the Nordic research organizations, industry and the computer societies. The emphasis of the workshop is to encourage interchange and cooperation between the research community and the industrial and software development community. The theme of the workshop is applied security, i.e., all kinds of security issues for all kinds of information technology systems. We are in particular looking for contributions that deal with technology transfer and application of research in development. Furthermore, this year's NORDSEC will look more specifically at several Special Topics that are closely related to Computer Security, but are not often discussed in the same forum: Software Engineering, Virus Protection, and Privacy Protection.
