摘要：
Role-based access control (RBAC) has been proposed as an alternative solution for expressing access control policies. The generalized temporal RBAC (GTRBAC) extends RBAC by adding time in order to support timed based access control policies. However, GTRBAC does not address certain issues of concurrency such as, synchronization. We propose an approach to the expressions of time and concurrency in RBAC based on timed Petri nets. A formal verification method for access control policies is also proposed.
