摘要
远程访问意味着网络变得更加“开放”,开放的网络需要完善的安全机制来确保网络的安全运行 .文中基于自行研制的访问服务器 (NAS) ,研究和实现了分布式远程访问安全管理系统 ,给出了基于 Client/ Server的系统结构模型和基于 Petri网的系统安全模型 .该系统实现了远程访问用户的安全认证、访问授权和记费管理 .
Remote access means that networks are becoming more 'open', Open netework needs self contained security mechanism to insure its run in security. Using network access server developed by ourselves, a distributed security administration system for remote access based on client/server structure is designed and implemented in this paper. The system security model based on Petri net is proposed. The system achieves identity authentication, access authorization, and accounting management to the remote access users.
