ABSTRACT
Wormhole attacks enable an attacker with limited Resources and no cryptographic material to wreak havoc on
wireless networks. Initial research focused that this attack is possible only on Adhoc networks, but in present
condition wormhole attack is possible on infrastructure based wireless LANs also. We propose architecture and
analyze the possibility of wormhole attack along with a countermeasure to avoid such an attack. The proposed
mechanism involves the shared information between communicating Access Points to prevent Rouge Access Points
from masquerading as false neighbours. Our defense greatly diminishes the threat of wormhole attacks and
requires no location information or clock synchronization.
