摘要
基于角色的委托授权模型旨在解决传统授权管理的集中性和复杂性问题,从而满足分布式计算环境的需求。本文在RBAC96模型的基础上,给出了一种扩展的基于访问许可和角色的两级委托授权模型———PRBDM及其面向对象的建模过程。该模型降低了委托授权的粒度,解决了分布式环境下多Agent授权管理的复杂性问题。
Role-Based Delegation Model mainly solves the centralization and complexity questions of traditional authorization management, and satisfies the requirement of distributed computing environment. The paper gives a Permission and Role-Based Delegation Model and Ob- ject-Oriented Modeling in the basis of RBAC96 Model. The model reduces granularity of Delegation, and solves the complexity question of multi-agents authorization management in the distributed environment.
