无线局域网作为一种无线接入技术得到了迅速的发展,但是它的安全机制却存在很大的安全隐患。如何保证无线局域网的安全性已成为目前重要的研究课题。其中,认证机制是安全机制的重要内容。无线局域网采用IEEE802.1x协议认证。本文针对IEEE802.1x协议容易受到中间人攻击和会话截取的缺陷,提出了协议的改进方案。主要在现有的IEEE802.1x协议的基础上增加客户端和接入点AP之间的相互认证。
Wireless LAN as a wireless access technology has been rapid development, but its security mechanism there is a big security risk. How to ensure the security of wireless LAN has become an important research topic. Among them, the certification mechanism is an important part of the security mechanism. Wireless LAN using IEEE802.1x protocol certification. In this paper, IEEE802.1x protocol vulnerable to man-in-the-middle attacks and session interception defects, proposed protocol improvements. Mainly based on the existing IEEE802.1x protocol to increase the mutual authentication between the client and the access point AP.
