Impact of channel sparsity and correlated eavesdropping on secret key generation from multipath channel randomness

Abstract

We study secret key generation from reciprocal multipath wireless channels modeled as multiple parallel fading channels. We consider two channel characteristics that heavily impact secret key capacity: channel sparsity and correlation between main and eavesdropper's channels. We propose a joint model to capture the channel sparsity and correlated… (More)
