| 摘 要： | 角色委托是RBAC模型需要支持的一种重要安全策略。其主要思想是系统中的主动实体将角色委托给其他主动实体,以便以前者名义执行特定的工作。提出一个基本的角色委托模型,在该模型的基础上,从应用出发,分别在时间约束、部分委托约束、角色依赖约束、层次角色模型的委托限制方面进行了扩展,给出了委托权限的回收方法,为模型在实际环境中的应用奠定了基础。

| Abstract: | Role delegation is an important security policy that should be supported for RBAC model.The basic idea of delegation is that some active entities in a system delegate their roles to other active entities to carry out some specific functions on behalf of the former.This paper presents a basic role-based delegation model.Based on it and proceeding from the application,some extensions to this model are explored,including time constraint,partial delegation constraint,role dependency constraint,and delegation re... |
