An Improved RBAC96 Model with Range Restricted

The modern information management systems are built on basis of the Internet, the online system nearly includes all business of an enterprise, and almost every employee has to complete some certain operations in the system. Therefore, the security plays an important role in the running of an online information management system. Access control is a significant component of the security measures. We can see easily if an online system is mature and reliable through its access control module. RBAC96 is a relatively mature access control mechanism. This paper is based on RBAC96 model prototype, and makes it improved with range restricted mechanism, which could make the whole access control become more secure, the control become more accurate.
