EAP-FAST在公共无线局域网安全接入控制中的研究及实现

The Research and Implementation of EAP-FAST Protocol in Public Wireless Local Area Network

Cisco公司于2004年提出基于隧道的灵活认证协议(EAP-FAST)以替代存在安全漏洞的LEAP认证协议,该协议具有安全性和易部署性的特点。文章论述了基于802.1x协议的EAP-FAST认证协议及其实现技术,并在公共无线局域网(PWLAN)综合实验平台上实现了EAP-FAST认证的客户端、认证者、认证服务器端功能。

Since the LEAP wireless authentication protocol is vulnerable to dictionary attacks, the flexible authentication via secure tunneling （EAP- FAST） was introduced by Cisco Corporation in 2004, which establishes a mutually authenticated protected tunnel to protect the authentication data. This friendly and easily deployable network access solution will be widely used in WLAN. The authors research and design this protocol in public wireless local area network, and implement the server in PWLAN integrate experimentation flat. function of EAP- FAST peer, authenticator and FAST
