%X Based on the research on the constraint of user activity in RBAC, this paper described a new RBAC model with conditions and periodic in user activity character. Analyzed the consistent state of the model and discussed the problem for maintaining the consistent state. Developed some algorithms to solve the state change problem of the time-constraint and the sessions. The new model made the system be more safer and effective. Also it could reduce complexity of mass network application and cost of safety management. It could create a great deal of economic and technological benefit in safety management of Internet.
