Multiple-input multiple-output (MIMO) systems are threatened by smart attackers, who apply programmable radio devices such as software defined radios to perform multiple types of attacks such as eavesdropping, jamming and spoofing. In this paper, MIMO transmission in the presence of smart attacks is formulated as a noncooperative game, in which a MIMO transmitter chooses its transmit power level and...
In this paper, we investigate the PHY-layer authentication that exploits radio channel information to detect spoofing attacks in multiple- input multiple-output (MIMO) systems. We formulate the interactions between a receiver and a spoofing node in the spoofing detection as a zero-sum game. In this game, the receiver chooses the test threshold of the hypothesis test in the PHY-layer authentication...
Multiple-input multiple-output (MIMO) techniques allow for multiplexing and/or diversity gain, and will be widely deployed in future wireless systems. In this paper, we propose a MIMO-assisted channel-based authentication scheme, exploiting current channel estimation mechanisms in MIMO systems to detect spoofing attacks with very low overhead. In this scheme, the use of multiple antennas provides...
