A method of providing secure communications between a base station, a relay station, and a mobile station in a communication network includes authenticating the mobile station over the communication network; generating, by the base station, security material, wherein the security material comprises at least one of a traffic encryption key (TEK) and a message authentication code key (MACK); transmitting, by the base station, the security material to the mobile station; and transmitting, by the base station, the security material to the relay station.
