This book presents the most interesting talks given at ISSE 2004 - the forum for the interdisciplinary discussion of how to adequately secure electronic business processes.

Adequate information security is one of the basic requirements of all electronic business processes. It is crucial for effective solutions that the possibilities offered by security technology can be integrated with the commercial requirements of the applications. The reader may expect state-of-the-art: best papers of the Conference ISSE 2004.

The Information Security Solutions Europe Conference (ISSE) was started in 1999 by EEMA and TeleTrusT with the support of the European Commission and the German Federal Minis try of Technology and Economics. Today the annual conference is a fixed event in every IT security professional's calendar. The aim of ISSE is to support the development of a Euro pean information security culture and especially a cross-border framework for trustworthy IT applications for citizens, industry and administration. Therefore, it is important to take into consideration both international developments and European regulations and to allow for the interdisciplinary character of the information security field. In the five years of its existence ISSE has thus helped shape the profile of this specialist area. The integration of security in IT applications was initially driven only by the actual security issues considered important by experts in the field; currently, however, the economic aspects of the corresponding solutions are the most important factor in deciding their success. ISSE offers a suitable podium for the discussion of the relationship between these considerations and for the presentation of the practical implementation of concepts with their technical, or ganisational and economic parameters."
