Secure key exchange in wireless networks

We investigate the problem of exchanging a se- cret 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 [1], the scheme presented here makes use of erasures over the wireless channel. In essence, this work can be seen as an extension of [1] for multi-hop networks instead of a single-hop network. We extend the approach and investigate the performance of our proposed protocol.
