Many applications in wireless sensor networks (WSNs) demand security. The standart low-power wireless sensors (TmoteSky, MICA2) have severe resource constraints. Despite some work on the adaptation of public-key cryptography to the resource constrained sensors, it is still not obvious whether the resources on the sensors are sufficient for the current asymmetric algorithms run in decent time and space...
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, we first identify a possible attack on MMR WiMAX networks in which a rogue base station (BS) or relay station (RS) can...
