基于无线局域网的认证方法研究

Research on authentification mechanisms based on WLAN

以无线局域网中的身份认证方式为研究对象,在研究WEP认证、IEEE802.11i认证的基础上,基于安全协议设计规范中通信实体间的相互认证原则,将现有的IEEE802.11i中的伪双向身份认证改进后使之为真正的双向认证机制,经过形式化的仿真分析表明对IEEE802.11i的改进可以防止各种假冒攻击,进一步保证了通信双方的合法性。

This paper takes the ways of identification in WLAN as its object of study,on the basis of the identity of IEEE802.11i,WEP,as well as the reciprocal identification mechanism of communication entities in the security protocol design,it improves the current IEEE802.11i pseudo-two-way and makes it the real two-way authentication mechanism.The formalized simulation analysis shows that the improvements of IEEE802.11i can prevent various forged attacks so that the validation of the both sides of the communication is assured.
