In this paper, we propose an information-theoretic scheme which achieves a new rate-equivocation region for the four-terminal relay-eavesdropper channel. The coding scheme used to achieve this region is a combination of the partial decode and forward, compress and forward and noise forwarding strategies. In this strategy the relay cooperates with the source to have both a reliable and secure communication by decoding some part of the source message, compressing the received signal and also sending the codewords independent of the transmitted message. Using this scheme we can obtain the perfect secrecy capacity of the semi- deterministic and deterministic relay channels.
