摘要
本文的研究基于货运铁路无线网络中的AAA(认证、授权、计费)系统,提出了一种针对铁路无线网络的认证授权方案,并做了具体的研究与实现。该AAA系统基于RADIUS协议,针对铁路系统的特殊应用进行了定制化的设计和实现。本系统可以对要接入铁路无线网络的客户端进行身份认证,并能根据客户端所属的业务组分配特定的网络使用权限,对铁路无线网络的权限管理和安全发挥重要作用。
The research was based on AAA（Authentication,Authorization,and Accounting） System of Freight Railway Wireless Network.The paper proposed a program of authentication and authorization for Railway Wireless Network.Facing with the special application of Railway System,it was designed and implemented the AAA System which was based on RADIUS protocol.The AAA System could identify the user who would access the Railway Wireless Network and assign some specific permissions to access the Wireless Network according to the user belong to the service group.So the AAA System could play an important role to the management and security of Railway Wireless Network.
