Secret-Key Agreement over Non-Coherent Block-Fading Channels with Public DiscussionSecret-Key Agreement • December 26th, 2014
Motivated by recent interest in physical-layer secret-key generation over wireless fading channels, we study the non-coherent secret-key generation capacity of a block-fading wireless channel with channel reciprocity and bi-directional (two-way) commu- nication. We assume a non-coherent main channel, i.e., the realization of channel gains on the main channel is not known to any terminal. The eavesdropper is assumed to have both perfect CSI of its own channel and orthogonal observations from the forward and backward channels. As our main result we establish new upper and lower bounds on the secret-key generation capacity with public discussion, which are structurally similar.
