摘要
首先介绍了基于角色的访问控制理论 ,讨论了其主要特征和优势 ,然后给出了一个以该理论为基础的访问控制系统的设计框架及实现技术 .该系统可以为FTP、WWW、TELNET提供访问控制服务 .系统的总体结构分为 :访问控制服务器、访问控制请求过滤器、角色及授权管理服务器 ,它们各司其职 ,协同服务 ,共同构成完整的访问控制系统 .
First, a theory of access control-role based access control was analyzed, and the characters and advantages of RBAC were discussed. Then, the infrastructure and implement techniques of our own access control system based on this theory were given. This system can provide access control service for FTP,WWW,TELNET. Its framework is presented with some core components: access filter server (AFS), access control server (ACS) and role and authorization management server (RAS). These three servers have distinct functions, while communicating and cooperating with each other as an integrated system. Finally, an instance using this system was given.
