Secure Key Exchange in Wireless Networks

We investigate the problem of exchanging a secret key within a group of wireless devices. In particular, we are interested in information theoretically secure key exchange schemes that enable honest nodes of a multi-hop network to establish a secret group key in the presence of an eavesdropping adversary. Similarly to, the scheme presented here makes use of erasures over the wireless channel. In essence, this work can be seen as an extension of for multi-hop networks instead of a single-hop network. We extend the approach and investigate the performance of our proposed protocol.
