Wireless client puzzles in IEEE 802.11 networks: security by wireless.

Conference item

Resource-depletion attacks against IEEE 802,11 access points (APs) are commonly executed by flooding APs with fake authentication requests. Such attacks may exhaust an AP's memory resources and result in denied association service, thus enabling more sophisticated impersonation attacks accomplished by rogue APs. This work introduces the concept of wireless client puzzles, a protection method which assists an AP to preserve its resources by discarding fake requests, while allowing legitimate c...
