Research on Semantic Security Supply-and-demand Policy for Web Service
Haiguang Lai, Pla Uni · Journal of Sichuan University · 2011
A novel approach based on semantics was proposed to express and match the security supply-and-demand policy of web service.Through constructing a general security ontology,the definition method and matching algorithm of semantic security supply-and-demand policy for web service were presented,and the matching problem of policy was translated into the subsumption reasoning problem of semantic concept.Both the theoretical analysis and experimental evaluation showed that the proposed approach can present the necessary semantic information in the representation of policy and effectively improve the accuracy of matching result,thus overcomes the deficiency of the syntactic approaches.This approach can also simplify the definition and administration of the policy at the same time,which thereby provides a more effective solution for the expression and matching problem of security policy in web service environment.
