摘要
研究了基于角色的访问控制(Role-Based Access Control,RBAC)2001的权限管理模型,针对该模型中存在的问题,在传统权限模型中引入对象组(object_group)的概念,构建出基于对象组的权限模型,并在此基础上提出了基于对象组的RBAC(GB-RBAC)模型,简化了管理员的操作,实现了权限的及时动态管理。
The management of permission in the Role-Based Access Control（RBAC） 2001 model is studied in this paper. Aiming at problems of this model, the conception of objectgroup is introduced into the traditional model of permission, and the model of permission based on object_group is constructed. Then, a new RBAC model based on object group（GB-RBAC）is presented, which makes the operation of administrators easy and implements the dynamic management of permission in time. GB-RBAC model is more fit for the application and management of corporations.
