Towards cross-domain security properties supported by ontologies

Abstract

Security is considered as a major driver for the success of E-Business, especially in a business-to-business environment. Current research activities in this area are conducted in European Union funded research projects, such as TrustCoM putting an emphasis on the collaborative aspects of business processes across administrative and trust domains. With respect to the tendency of business partners to set up their own security islands, e.g. based on isolated Public Key Infrastructures (PKIs), this development introduces a contradiction for collaborative business process. Clearly expressed process related security requirements across domains can not be met by domain specific security infrastructures. This contribution explores the possibility to bridge the identified gap using semantic relationships contributed by ontologies. © Springer-Verlag 2004.
