A new methodology to exchange a random secret key between two parties. The diverse physical characteristics of the wireless medium and device mobility are exploited for secure key exchange. Unique physical characteristics of wireless channels between the two devices are measured at different random locations. A function of these unique characteristics determines the shared secret key between the two devices.
