摘要
针对基于角色的访问控制模型的局限性 ,提出了一种基于角色与基于规则相结合的访问控制模型 ( RRBAC) .该模型以可扩展的用户组织结构为框架 ,根据用户组织结构定义角色的属性及其继承关系 ,用参数化的规则集合描述了用户组织结构中由上下级关系所引发的操作许可 ,实现了面向群组协同工作的分级权限管理体系 .最后 。
For the limitation of role based access control model, a role and rule based access control model is proposed. The frame of the model is an extendible organizational structure of users, the attribute and inherited relation of role is defined according to the organizational structure of users, the permissions introduced by the level relation of the organizational structure of users is depicted by the parameterized rule set, and the group cooperative work oriented hierarchical authorization management system is implemented. Then the design instance is given by combining database design.
