Research on Policy-Based Service-Oriented Computing Security

Abstract

This article described the Web Services security protocols, and the policy description language XACML was analyzed in detail in the Web Services. XACML is characterized by the strong ability of expansion and the favorable inter-operation in the access control of the Web Services, which are concluded from the comparison in both SOA strategic architectures. A collection of XACML policy combination algorithms and decision algorithms were discussed in the policy-based service-oriented computing, then the policy control and access control mechanism were also illustrated, and the corresponding decision model was described, at last the development of XACML was prospected.
