Wireless local area networks (WLAN) are increasingly deployed because of the freedom wireless communications afford and the decreasing costs of the underlying technology. Together with its higher and higher popularity, the Internet has also shown more and more weakness of wireless protocols that lead to attacks. There are a lot of efforts to improve the security of wireless network (from IEEE 802.11 standard protocol to 802.11i builds on top of the IEEE 802.1X standard). But these cannot defend network from denial of service (DoS) attacks. In this paper we focus on analyzing denial of service attacks on 802.11-based protocols, especially de-authentication and disassociation attacks that are called ldquodisrdquosing attacks and propose a solution for defending against ldquodisrdquosingrdquo attack using letter-envelop protocol to authenticate management frames.
