A Policy Language for Adaptive Web Services Security Framework

How to resolve access control on Web services has become one of the important research tasks about the application of Web services. In this paper, we propose a policy based adaptive Web services security framework. In this framework, the ReiT policy is a declarative language based on the rules and ontologies. The non-structural knowledge is represented by rules and the structural temporal knowledge is represented by ontology. Moreover, we propose a mixer reasoning mechanism to evaluate the ReiT policy. The access control policy including the context of the user and Web services is evaluated by the reasoner. According to the evaluated result agent authorizes the access control of the Web services.
