摘　　要：角色安全访问控制如何在分布式对象系统中实现越来越受到人们的重视。本文提出一种新方法具有自动角色激活的安全中间件组件,是一种容易觉察安全的基于角色访问控制应用系统。基于角色访问控制已经被认为是传统随意性与强制性访问控制模型的整合。The paper shows how role-based access control（RBAC）models can be implemented in distributed objectbased systems that follow OMG/ORB standards.The paper introduces a novel approach that provides for automatic role activation by the security components of the middleware,which brings role-based access control to securityunaware applications.Role-based access control has been being recognized as an integration to traditional discretionary and mandatory access control models.
