A two-way system with two sources and one relay node for secrecy communication in the presence of an eavesdropper is investigated, where the two sources communicate via the relay node, and Artificial Noise (AN) is introduced by relay node to deteriorate the eavesdropper's channel. It is robust since only the two sources need to know the channel statistics between themselves and relay node. Compared with the system without AN sending by relay node, AN is verified to enlarge the secrecy capacity.
