RBAC模型中角色继承关系的研究与改进


□ 张世龙 沈玉利

  摘 要:针对RBAC96模型中私有权限实现方法的不足,分析了现有改进方案的研究现状和不足,引入继承属性的概念,通过继承属性值实现权限公有与私有的划分,提出了角色继承时只创建继承关系的继承方案。引入权限重载概念,给出了多角色继承及权限重载时的冲突解决规则,采用广度优先搜索算法实现了角色权限的动态获取;结合实例说明了角色继承、权限重载、解除继承关系的实现方法。

  Abstract:

  In order to overcome the shortages of the implement method of RBAC96 model’s private permission, put forward a new inheritance scheme after the research, analyzed shortages of current improvement scheme, which only created inheritance relation.Introduced the concepts of inheritance attribution and permission override, and could identify the private permission in this scheme through inheritance attibution value. Presented the conflict rules about multiple roles inheritance and permission override. With the help of the breadth-first search algorithm, could get role permission dynamically. Finally, illustrated the methods of role inheritance, permission override and remove inheritance relation with some examples.
