Secure Semantic Web Service Using SAML

The Semantic Web’s success will depend on the implementation and use of Web service, becoming preeminent in E-commerce, which will likely be agent-based in the future. Agents use the large amount of information available over the web, but it will allow agents more subtle attacks. Agents and supporting technologies need to be secure and reliable for safe Web service as they adopt more mission critical roles within Web services,. In this paper, we’ll discuss agent security on the Semantic Web. On the Semantic Web, agents play different roles in different platforms, dynamically change their access requirements, and act on behalf of users with different access privileges. In order to make agents secure, we’ll propose a method that agents dynamically exchange their authentication and authorization information using SAML. And then, a few threats that may be happened in transit and countermeasures will be presented. Finally, we’ll conclude our talks by presenting further works.
