| 摘 要： | 介绍了基于角色的访问控制基本模型,针对RBAC基本模型的局限性提出了改进方案:通过一般继承、扩展继承解决了基本模型中的角色完全继承缺陷,引入用户组增强了RBAC基本模型的控制粒度。对扩展模型给出了在分布式新闻编辑系统中的应用实例。

| Abstract: | This paper describes a Role-Based Access Control model,and presents an improved scheme according to the limitation of RBAC in which we have solved the defect in role full inheritance by normal inheritance and extended inheritance and introduced user group to improve the controllable granularity in RBAC.Finally,an application of extended model is given in the distributed news-edited system. |
