“…In the case of perfect CSI availability at the jammer, it has been shown that correlated jamming is optimal in point-topoint as well as multi-user and multiple input multiple output systems [13], [14]. We will demonstrate that the same is true in the case of SKG systems when α = 0.…”

Abstract-Secret key generation (SKG) schemes have been shown to be vulnerable to denial of service (DoS) attacks in the form of jamming. In this paper, a comprehensive study on the impact of correlated and uncorrelated jamming in wireless SKG systems is presented. First, optimal signalling schemes for the legitimate users and jamming approaches for an active adversary launching a DoS attack on the SKG system are derived. It is shown that the legitimate users should employ constant signalling. On the other hand, the jammer should inject either correlated jamming when imperfect channel state information (CSI) regarding the main channel is at their disposal, or, uncorrelated jamming when the main channel CSI is completely unknown. In both cases, optimal power allocation policies are studied under short-term power constrains for M block fading additive white Gaussian noise (BF-AWGN) channels. Numerical evaluations demonstrate that equidistribution of the jamming power is near-optimal in the case of uncorrelated jamming.

“…For simplicity, in the following, we assume that the legitimate users employ constant signalling X = Y = √ P. In the case of perfect CSI availability at the jammer, it has been shown that correlated jamming is optimal in point-to-point as well as multiuser and multiple input multiple output systems [30,31]. We will demonstrate that the same is true in the case of SKG systems when α = 0.…”

Secret key generation (SKG) schemes have been shown to be vulnerable to denial of service (DoS) attacks in the form of jamming and to man in the middle attacks implemented as injection attacks. In this paper, a comprehensive study on the impact of correlated and uncorrelated jamming and injection attacks in wireless SKG systems is presented. First, two optimal signalling schemes for the legitimate users are proposed and the impact of injection attacks as well as counter-measures are investigated. Finally, it is demonstrated that the jammer should inject either correlated jamming when imperfect channel state information (CSI) regarding the main channel is at their disposal, or, uncorrelated jamming when the main channel CSI is completely unknown.

“…3, but note that this representation does not hold for the extensive game with perfect information in Section III. Solving for the Nash equilibrium in mixed strategies, we obtain the optimal strategies and equilibrium outcome exactly as shown in (10). We conclude this section by describing a refinement to the sequential equilibrium solution, which takes into account the possibility of opponents making small errors while executing their equilibrium strategies.…”

Abstract-This paper investigates transmission strategies in a MIMO wiretap channel with a transmitter, receiver and wiretapper, each equipped with multiple antennas. The secrecy rate between the transmitter and the legitimate receiver is chosen as the performance metric. In a departure from existing work, the wiretapper is able to act either as a passive eavesdropper or as an active jammer, under a half-duplex constraint. The transmitter therefore faces a choice between allocating all of its power for data; or broadcasting artificial noise along with the information signal in order to selectively degrade the eavesdropper's channel. We model the network as a dynamic zero-sum game in extensive form with the secrecy rate as the payoff function. We first examine subgame-perfect equilibrium strategies in the extensive form of the game with perfect information. We then discuss sequential and trembling hand perfect equilibria for the case of imperfect information. Finally, numerical simulations are presented to corroborate the analytical results.
