Quadratic Residue Based Client Puzzle Distributed by Beacon Frame in DoS-Resistant Wireless Access Authentication

Wireless LAN suffers from serious vulnerabilities that may lead to denial of service attacks due to its opening link, limited computing power, dynamic node and other reasons. As a kind of DoS attacks, resource depletion attacks against IEEE 802.11i protocol exhaust Access Points (AP) resources while the legitimate user's networks access will be obstructed. This paper focus on request and authentication request flood DoS attacks. A beacon and extracting square roots based DoS-resistant scheme of IEEE 802.11i wireless authentication protocol is proposed to improve the DoS-resistant ability of IEEE 802.11i wireless networks.
