Abstract:
This paper describes a semantic approach for modelling security requirements of requesters and providers of Semantic Web Services. These semantic descriptions can be used either during semantic service discovery or service selection phase for automatic compatibility verification of the security requirements of a service requester and provider. The security requirements model, ontology classifying existing security services and mechanisms, and a semantic matchmaking method relying on description logics are described in detail. This work is related to several semantic and non-semantic Web Services standards. The relationship to the most relevant of them has been worked out.
