摘要
通过对IEEE 802.11i四次握手过程的研究,发现其存在缺陷并可能受到的拒绝服务攻击。针对这一安全漏洞,研究TPTK、重用Nonce、消息1身份认证三种改进方法,并对这三种改进方法的安全性进行分析。这三种改进方法在避免拒绝服务攻击的同时,都给无线局域网带来新的安全威胁。提出进一步研究的思路与方向。
Based on the research on the IEEE 802.11i 4-way handshake, it is found that there exists de- fects which will lead to denial of service attacks. Aiming at this security vulnerability, studies three improved methods, TPTK, re-Nonce and authentication to the initial message, and ana- lyzes the security of these three methods. It is found that these improved methods will bring new security threats to WLAN. And puts forward the direction of further research.
