Detection and Localization of Multiple Spoofing Attackers in Wireless Networks

Wireless spoofing attacks are easy to launch and can significantly impact the performance of networks. Although, the identity of a node can be verified through cryptographic authentication, conventional security approaches are not always desirable because of their overhead requirements. In this paper, the authors propose to use spatial information, a physical property associated with each node, hard to falsify, and not reliant on cryptography, as the basis for detecting spoofing attacks; determining the number of attackers when multiple adversaries masquerading as the same node identity; and localizing multiple adversaries.
