| 摘 要： | 针对传统XML描述的基于角色的访问控制(RBAC)模型在角色权限继承、约束方面支持的不足，提出了一种基于XML图的RBAC3模型。该模型通过属性引用的方式实现了多重继承并引入面向对象中私有继承的概念，使角色的私有权限得到保护。同时，通过引入互斥权限的概念简化了责任分离的实现。

| Abstract: | In order to overcome the shortages of role inheritance and constraint in Role-Based Access Control (RBAC), an improved XML-described RBAC3 model was put forward. This model implemented multi-inheritance by attribute reference, protected the private permissions by private inheritance and simplified the implementation of Separation of Duty (SoD) by mutual exclusive permissions. |
