Abstract

802.11i is the latest security standard for wireless LAN (WLAN). It provides data confidentiality and integrity. The 802.11i 4-way handshake and key management remains secure against any attack which could compromise the key. However, availability protection is still an issue as 802.11i is subjected to denial of service attacks. Since Message 1 in the 4-way handshake is not protected by any mechanism, forging these messages is possible. This paper presents a light and simple implementation to deter DoS attacks against the 4-way handshake protocol.
