Abstract

We present a compressive sensing (CS) approach for secret key agreement based on UWB channel reciprocity. More generally, we show that the CS problem can be used for solving the distributed source coding problem. We also show that the proposed CS-based secret key agreement protocol (CS-SKAP) provides perfect secrecy, a better key agreement probability, and sometimes a longer secret key length, compared to the traditional syndrome-based distributed source coding techniques.
