Wireless key establishment is a method that allows two legitimate devices to establish a shared key utilizing the randomness inherent in the wireless channel. In wireless context, the receiver and the transmitter of one wireless link will observe the same channel simultaneously. Such reciprocity property enables two legitimate devices to extract the same characteristics of the channel and agree on the same shared key. Meanwhile, due to the spatial uncorrelation of wireless channels, for two transmitters at different locations, the channels observed by the same receiver are different. Thus, the key established between a pair of wireless devices is confidential to a third un-colocated party.

Historical Background

Wireless devices have been widely used due to its remarkable evolvement in the past two decades. Unlike traditional communication, a wireless device can...
