Supporting Complex Access Control Policy in PDM System
Based on previous works, this paper proposed an extended access control model for PDM system. In this model, complex access control policies are expressed and enforced to ensure the security of user role assignment, delegation and revocation of PDM system. To reduce system administrator’s work, the model provides an auto revocation mechanism which can be triggered by time, access control policies and user states. This paper also propose an implementation system architecture, an auto revocation algorithm and some examples to show how this complex policy supported access control model works in PDM system.
