Research and Implementation of Role-Based Access Control Model Based on Partition Number

The role-based access control (RBAC) model has garnered great interest in the security community due to the flexible and secure nature of its applicability to the complex and sophisticated information system. But there are few research results about implementation analysis on RBAC. With the help of partition number theory, this paper provides a method of RBAC to implement data access permissions control in the major application system. One of the important research areas in this model is that the agent mechanism is introduced to implement RBAC. Secondly when a user enters the access system and gets a session, the user will be activated and the permission is granted simultaneously to ensure a safe and optimal operation in his session. Finally the implementation is analyzed for verifying the applicable value of the model.
