OWL-S Semantics of Security Web Services: a Case Study

摘要

The power of Web services (WS) technology lies in the fact that it takes integration to a new level. With the increasing amount of services available on the Web, solutions are needed that address security concerns of distributed Web service applications such as end-to-end service requirements for authentication, authorization, data integrity and confidentiality, and non-repudiation in the context of dynamic WS applications. Semantic Web technology and Semantic Web services (SWSs) promise to provide solutions to the challenges of dynamically composed service-based applications. We investigate the use of semantic annotations for security WS that can be used by matchmakers or composition tools to achieve security goals. In the long-term we aim at establishing a security framework for SWS applications that include security services, authentication and authorization protocols, and techniques to exchange and negotiate policies. In this paper, we report on the first step toward this larger vision: specification, design, and deployment of semantically well-defined security services.
