Abstract
In PDM system, there exist many users, such as employees, partners, and customers. To protect resource from illegal access, it is very important to enforce access control policy in PDM system. RBAC is widely used as an access control model in PDM system. But, it is difficult for RBAC to support complex access control policy. This paper proposed a simple, flexible way to express and enforce access control policy. To keep the integrity of system security and make the system administer work easier, we propose auto revocation triggered by time and access control policy in our model. At the end of this paper introduces a system architecture and auto revocation algorithm. We also give some examples to show how this model works in PDM system.
