Wireless Network Physical Layer Intrusion Detection System

Reference#: P01807

Wireless networks pose a number of security challenges: inherently non-exclusive medium, dynamic topology, and processing/memory constraints of nodes. Existing intrusion detection systems rely chiefly on network-layer and high-layer protocol information as input systems. Also, they are not robust against certain classes of attacks such as datagram spoofing.

The Johns Hopkins University Applied Physics Lab has developed an intrusion detection system that utilizes physical-layer information to enhance detection performance for wireless networks. Furthermore, this technology can detect attacks by adding a transmitter identification and location capability.
