Abstract

For the Computer Supported Collaborative Design (CSCD) environment’s groups, dynamics and distribution characteristics, the paper proposes a Task & Role-Based access control model (T & RBAC) and makes the informal definition of the model. The T & RBAC model is based on the T-RBAC model, and extends the definition of the Users, Roles, Tasks, Permissions and the other factors. In the T&RBAC model, Roles are classified into two classes : job position and business role. As a passive role, permissions are preasigned to the job function Role. By the other way, the business role is assigned to the task in the business process, and the permissions are actived by the context of the task’s excuted status, so that the paper realizes the active and passive access control. Finally, we applied the T&RBAC model in the CSCD system and validated the model.
