Alibi Framework for Identifying Reactive Jamming Nodes in Wireless LAN

Free registration required

Executive Summary

Reactive jamming nodes are the nodes of the network that get compromised and become the source of jamming attacks. They assume to know any shared secrets and protocols used in the networks. Thus, they can jam very effectively and are very stealthy. This paper proposes a novel approach to identifying the reactive jamming nodes in Wireless LAN (WLAN). It relies on the half-duplex nature of nodes: they cannot transmit and receive at the same time. Thus, if a compromised node jams a packet, it cannot guess the content of the jammed packet.
