Secret key sharing by means of reconfigurable antenna systems

We focus on the extraction and sharing of a secret key between wireless terminals, by means of the measurement of the characteristics of the common wireless channel. In particular, we show that it is possible to increase the length of the shared key with a limited number of transceivers, and a significant reduction in the overall system complexity, using reconfigurable antenna systems.
