The Relay Channel with a Wire-tapper

— In this work a relay channel with a wire-tapper is studied for both discrete memoryless and Gaussian channels. The wire-tapper receives a physically degraded version of the destination’s signal. We find inner and outer bounds for the capacity–equivocation rate region. We also argue that when the destination receives a physically degraded version of the relay’s signal, inner and outer bounds meet for some special cases.
