Reactive jamming is considered the most powerful jamming attack as the attack efficiency is maximized while the risk of being detected is minimized. Currently, there are no effective anti-jamming solutions to secure OFDM wireless communications under reactive jamming attack. On the other hand, MIMO has emerged as a technology of great research interest in recent years mostly due to its capacity gain...
Recently, an interesting primary transmitter authentication scheme was proposed. The main idea of this scheme is to have the primary transmitter embed cryptographic authentication tag at the physical layer. There are a number of features that make this scheme attractive. In this paper, we investigate the effective coverage areas for the primary and secondary receivers before and after applying this...
