Abstract
Wireless devices in proximity are securely paired with one another autonomously by generating a common cryptographic key directly from a time-varying wireless environment shared among the wireless devices. The shared key can be used by the wireless devices to authenticate each wireless device's physical proximity and then to facilitate confidential communication between the wireless devices. The algorithm used to create the shared key is secure against a computationally unbounded adversary and its computational complexity is linear in the size of the shared key.
