Abstract

We consider the relay-eavesdropper channel with generalized feedback at the source node. In the presence of a wire-tapper, the source can send confidential messages to an intended receiver with the help of the trusted relay. With a generalized feedback from the relay to the source node, the cooperation between the source node and relay node may be enhanced. The achievable secrecy rate region for this channel is derived by using rate splitting strategy and decode-and-forward (DF) strategy at the source node and compress-and-forward (CF) strategy at the relay node.
