The Research of Access Control in E-Government System

摘要：

Role-based access control (RBAC) with a three-layer user-role-permission structure has become widely accepted as an attractive access control technology. However, RBAC is very hard to meet the demands of E-Government System with large number of user and role. This paper proposed an advanced RBAC model named Group Hierarchy Role-Based Access Control (CH-RBAC) for the requirements of E-Government System with complex user relationships and diversified business process, In the optimized RBAC model, tradition user - role assignment have been reformed to user group - role group assignment which improve the scalability and adaptability of access control. Finally, we design and implement the extend model that emphasis the way to carry out access control module with the low coupling.
