The application of role-based access control in workflow management systems

Taking the characteristics of WfMS (workflow management system) and the requirement of real application into consideration, this paper presents a role-based access control model, which is suitable to workflow management systems, and applies it to the process discomposition-based workflow model. The problem of the static and dynamic constraints in role-based access control and authorization for WfMS is introduced in detail. Finally, it analyzes the architecture and implementation of a WFMS enactment system, which supports RBAC.
