Attribute-Based Access Control of Collaborative Design Systems
The current research in access control is analyzed, and the features of access control in collaborative design systems are discussed. According to the new requirements of the access control technology in collaborative design systems, the attribute-based access control (ABAC) model is improved to a new one: supporting role and task ABAC model. The concept of role entity and task entity is introduced into the ABAC model. The formal definition and object model of the improved model are given, and the features of the newly-introduced model elements are discussed.
