| 摘 要： | 在分析传统基于角色的访问控制(RBAC)模型的基础上,对模型增加了角色继承约束和时间约束,增大了复杂系统中角色的粒度,提高了模型对复杂角色关系的适应性,实现了用户多级授权,并使得模型能够随时间动态变化,最后给出其在实际系统中的应用实例,从而进一步论证了其合理性和实用性。

| Abstract: | 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. |
