Abstract: Role-based access control (RBAC) technology is rapidly developing along with the Internet.In RBAC,role is an important concept, and must be properly constructed to reflect organizational access control policy and needs.The existing models of RBAC neglect the dynamic features of activated roles the paper introduces a dynamic model,every object of role-playing runs in particular context, which restrictes users rights dynamically and control user's interaction actively. The model is suitable for distributed and interactive applications,and it can improve control efficiency.
