Secure Mutual Authentication Protocols for Mobile Multi-Hop Relay WiMAX Networks Against Rogue Base/Relay Stations

Mobile Multi-hop Relay (MMR) WiMAX networks have attracted lots of interest in the wireless communication industry recently because of its scalable coverage, improved data rates and relatively low cost. However, security of MMR WiMAX networks is the main challenge. In this paper, the authors first identify a possible attack on MMR WiMAX networks in which a rogue Base Station (BS) or Relay Station (RS) can get authenticated and gain control over the connections. They also show that the current standard does not address this problem well. They, then propose a set of new authentication protocols for protecting MMR WiMAX networks from rogue BS and rogue RS attacks.
