摘要
介绍了远程用户拨号认证(RADIUS)协议的工作原理和使用的安全算法,分析了其安全性和可能存在的安全漏洞,提出了改进的RADIUS协议以增加网络的安全性能.利用该协议建立了提供给运行商用于无线接入网络的网络认证、授权和计费(AAA)系统.该系统不增加协议的通信复杂性,并具有简单和易实现的特点.
By analyzing the principle of remote authentication dial in user service (RADIUS) protocol and the applied security algorithm, an improved RADIUS protocol was proposed to enhance the security performance of networks. Based on the improved protocol, AAA (authentication, authority and account) architecture was set up for the Internet service providers. The AAA architecture for wireless gateway does not increase the complexity of the communication systems, and is simple and easy to implement.
