Research on the Method of Attributes-Based Cross-Domain Access

This paper purposes a cross-domain access control framework base on the attributes synchronization, and purposes a cross-domain access control method in the framework, this method achieves the attributes synchronization between the base domains and outside domains. The method can timely and actively response the changing of the subject attributes to the outside domain, achieves fast matching of the mandated rules and dynamic authority in the cross-domain process. This method improves dynamic cross-domain access problems of IRBAC2000 too.
