Relaying and cooperation have re-emerged as important research topic in the wireless communication over the past decade. IEEE 802.16j Multihop relay network is assiduously developing to accomplish high capacity services with large cell coverage. Considerable interest currently exists in the exploitation of Relay based Wimax. This is mainly the result of lower infrastructure cost and high data transfer rates compared to existing 3G. However due to lack of physical boundaries and injection of distributed relays, it is known to be more vulnerable to security holes as a trade off. In this paper, the authors propose a new distributed authentication key scheme for Multihop Relays IEEE 802.16j network service. The propose scheme uses decode and forward relays with localized authentication.
