| 摘 要： | 本文提出了适用于开放分布系统的基于RBAC和策略实施的协调模型(RBPEC).RBPEC模型引入了协调组的概念,把需要进行交互才能完成整体任务的多个软件实体放在一个协调组中.RBPEC协调模型把协调和访问控制两者结合起来,引入基于角色的访问控制为协调系统作安全性检查,系统的协调策略可以在分布环境下实施.RBPEC协调模型具有安全和可扩展两大特点.

| Abstract: | An RBAC based and policy enforcement coordination model suitable in open distributed system is described. A set of entities interacting with each other for a common glohal system task constitutes a coonlination group. In this model coordinalion is combined with access. Role based access control is introduced for security concerns and coordination policy is enforced in a distributed.The model has two characteristics of being secure and scalable. |
