Abstract

We consider the problem of secure communication over a (not necessarily degraded) wiretap channel with two-sided channel state information available at the transmitter and the main receiver, respectively. Using the time sharing argument [1], we establish an achievable rate equivocation region for this channel model. The obtained achievable region generalizes several existing results in the literature. More importantly, through examining various cases with different knowledge of channel state information, we provide a systematic study of the impact of channel state information on secure communication.
