Abstract:
This paper studies the security of key establishment and management protocol of IEEE 802.11i 4-way handshake, and it is found that there exists security vulnerability, which will lead to a DoS attack. Based on the study, an improved method to enhance the security of IEEE802.11i 4-way handshake is developed.

摘要: 对IEEE802.11i协议中四次握手过程的临时会话密钥的协商和建立过程中的安全性进行了分析,发现在四次握手过程中存在安全隐患,并因此可能受到DoS(拒绝服务)攻击。在此基础上提出了一种改进方法,使四次握手过程的安全性得到进一步增强。
