| 摘 要： | 在对授权代理模型深入分析的基础上,提出了一种基于约束的用户-用户授权代理模型,给出了该模型的构成要素和体系结构,并且详细描述了该模型的职责分离约束以及代理判定关系,并在判定关系中描述了角色基数约束、用户基数约束和权限基数约束,最后给出了代理实施策略.

| Abstract: | Based on the deep analysis of delegation models,a constraint-basod user-to-user delegation model is proposed.The constitutes and the architecture of the model are given,and its duty separation constraints and delegation judicative relation are described.The role cardi- nality constraints,user cardinality constraints and permission cardinality constraints in delegation judicative relation are also described.Final- ly,the delegation policies for implementation are presented. |
