首先介绍了Radius协议,然后给出了基于Radius的三种分布式认证系统组网模式,并且分析了它们的认证流程,最后给出了Radius的Proxy功能在无线校园网中的一个应用,通过试验验证了集群式Radius认证系统的高效性和便利性,采用集群式认证是很好的借鉴。
This paper first presents the RADIUS protocol, then puts forward three different network frameworks of distributed authentication system, and analyzes their authentication process. Finally, it gives a specific application of wireless campus network based on radius's prxoy function, and its efficiency and convenience is proved throuth the experiment. It is a good reference for distributed authentication system.
