Detecting the presence of hidden wireless eavesdroppers
… possibility of detecting the hidden presence of wireless eavesdroppers. Such eavesdroppers employ passive receivers that only listen and never transmit any signals, making them very hard to detect. We show that even passive receivers leak RF signals on the wireless medium. This RF leakage, …

Secure protocols for wireless availability
Since wireless networks share a communication medium, multiple transmissions on the same channel cause interference to each other and degrade the channel quality, much as multiple people talking at the same time make for inefficient meetings. To avoid transmission collision, the network divides the …
