无线安全认证协议IEEE802.1x的改进
he improvement of wireless security authentication protocol IEEE802.1x
本文主要介绍了IEEE802.1x的体系结构和认证流程，分析了它的缺陷，从数据完整性保护角度出发，在EAPOL包中增加了一个Protection字段，提出了SDVIA（Source Data Verity and Integrity Authentication，数据真实性和完整性认证）认证。该认证技术可以弥补IEEE802.1x认证协议存在设计上的缺陷，有效的预防中间人和会话劫持攻击。
his paper mainly introduces system structure and authentication flow of IEEE802.1x, analyses its flaws, form the point of view data integrity protection, adds a Protection field in EAPOL package, proposes a authentication protocol SDVIA（Source Data Verity and Integrity Authentication）.This protocol technology can make up the design flaws of IEEE802.1x, and effectively prevent Man-in-the-middle-attacks or Session Hijack.
