基于802.11i的WLAN动态密钥管理机制分析及改进
Analysis and Improvement of Dynamic Key Management Based on WLAN 802.11i
-
摘要: 介绍了新一代WLAN安全标准802.11i, 研究了802.11i协议的动态密钥管理机制, 从四步握手角度对其安全性进行了深入分析, 指出了可能受到的DoS攻击.提出了两种改进设计方案, 有效避免了这些攻击, 进一步完善了无线局域网的安全性能.Abstract: The WLAN’s new generation of security standard IEEE 802.11i protocol is introduced, and the dynamic key management based on 802.11i was discussed, and its security is also analysised deeply from the 4-Way Handshake Protocol, then the possible Denial of Service attacks are indicated. To deal with these attacks, two improved measures were put forward to enhance the WLAN’s security.
