Wireless networks are vulnerable to intrusion and attack. Even the strongest encryption and authentication are not sufficient to protect the network. Because signal propagates in shared media, the very acts of transmission, easily detectable using simple devices, reveal crucial aspects of networking. For example, by listening the widely used RTS-CTS exchanges, an eavesdropper can guess the transmitter-receiver pair without decoding the content of the transmission. If eavesdropping sensors are geographically distributed in the network, a malicious attacker can obtain medium access control (MAC) and routing information and track messages propagating in the network, which allows the adversary to jam the network at a crucial time or launch a denial-of-service attack.
Lang Tong is the Irwin and Joan Jacobs Professor in Engineering at Cornell
University Ithaca, New York. Lang Tong received the B.E. degree from Tsinghua University, Beijing, China, in 1985, and M.S. and Ph.D. degrees in electrical engineering in 1987 and 1991, respectively, from the University of Notre Dame, Notre Dame, Indiana. He was a Postdoctoral Research Affiliate at the Information Systems Laboratory, Stanford University in 1991.
