| 摘 要： | 针对传统的基于角色访问控制（RBAC）模型的不足，在基于角色的权限访问控制的基础上，提出了一个扩展角色访问控制模型，新模型对角色和权限的概念进行了扩展，使得RBAC模型能够更灵活、高效地对系统进行权限访问控制，增强了访问控制安全。

| Abstract: | As a way to defend information＇s confidentiality and integrity, access control takes a quite important role in military system and commercial system. Role-Based Access Control（RBAC） Model has been generally used in morden sofeware systems, and it has become one of the hotspots in the field of information. On the basis of RBAC, an Extended Role-Based Access Control（ERBAC） model is introduced against the imperfections of the famous RBAC model. Then the applying process of this model is illuminated. In the improved model, the concepts of role and permission are extended, which makes RBAC model be applied to systems freely and efficiently, and strengthens the security of access control. |
