Abstract: Analyzes the deficiencies when traditional RBAC authorization model is directly used as workflow authorization one and its shortages to support time constraints and duty separation one. And a WFMS authorization model based on role control and time constraints is constructed, and how it meets the desires of least privilege and separation of duty is discussed.

Key words: RBAC, authorization, access control, time constrains, least privilege, duty separation , workflow
