Research and Application of an Improved Role-Based Access Control Model
Zhao Jing-zhong · Microcomputer Development · 2005
On the basis of analyzing the conventional RBAC model, presents an improved RBAC model with role-inherited constraint and time constraint. The improved RBAC model has better applicability to the complex role relations than conventional RBAC model, and it has the character of changing with the time. Finally, its application in a PM system is illustrated, which proves the model's reasonability and practicability.
