“…Different from the above works, our work mainly focus on the AN aided multi-antenna secure transmission. The works in [24,25,26,27] provided a CJ strategy for guaranteeing security in multi-antenna transmission system. However, only a jammer and a limited number of eavesdropping nodes are considered in the proposed works, which leads to a limited application scope.…”

Vehicular communication has emerged as a supporting technique for improving road traffic safety and efficiency in the intelligent transportation system (ITS). However, the wireless vehicular communication links may suffer from an eavesdropping threat due to the wireless broadcasting nature and high-mobility of vehicles. In practice, artificial noise (AN) assisted beamforming scheme can be utilized for fighting against multiple malicious eavesdroppers. Unfortunately, channel estimation errors caused by the high mobility of vehicles may lead to noise leakage at the legitimate receiver, thus resulting significant loss in the secrecy performance. In this paper, a joint cooperative jamming and AN aided secure transmission scheme is proposed in vehicular communication network by considering the imperfect channel state information(CSI). In this scheme, cooperative jammers are utilized for further enhancing physical layer security. We derive the closed-form expressions of the connection and secrecy outage probabilities in the presence of AN leakage and signal offset using a stochastic geometry approach. Furthermore, the proposed scheme is capable of maximizing the secrecy throughput in terms of relative vehicular velocity for balancing both the reliability and security of the legitimate link. We further comprehensively analyze the effect of key system parameters on secrecy performance through asymptotic analysis. Finally, the effectiveness of the proposed scheme is validated by numerical results.

Joint active and passive beamforming optimization for intelligent reflecting surface assisted proactive eavesdropping

et al. 2021

This paper investigates a three-node proactive eavesdropping system with the aid of intelligent reflecting surface (IRS), where a monitor tries to wiretap information and transmit jamming signals simultaneously to interfere with the suspicious link. The IRS is deployed around the suspicious users to reconstruct propagation channel. Meanwhile, with large low-cost passive reflecting elements, it can provide more spatial degrees of freedom to moderate the link quality. In order to degrade exposure risk of eavesdropping behavior, the authors' objective is to minimize the jamming power by carefully designing jamming beamforming vectors and the phase shifts under the constraint of reliable intercepted information. The formulated problem is non-trivial to solve due to the coupling variables and unit-modulus constraints. Fortunately, by using alternating optimization and successive convex approximation techniques, the original problem is transformed into convex form and a sub-optimal solution is achieved. Numerical results show that the proposed scheme can effectively reduce the jamming power and the number of the jamming antennas over benchmark schemes, which is quite suitable for covertly overhearing signal.

In this article, a land mobile satellite communication network with an external jammer to fight against the eavesdropper is investigated, where the hardware impairments are introduced to make the analyses more practical. It is worth noting that three jamming schemes, that is, the Gaussian noise jamming, the friendly jamming, and the scheme without jamming, are taken into account to explore the effect of the jammer comprehensively. The secrecy metrics such as the connectivity outage probability (COP), the security outage probability, and the secrecy throughput (ST), are derived for the passive eavesdropping scenario, while the ergodic secrecy capacity is analyzed for the active eavesdropping scenario. Moreover, to get intuitive insight from the closed-form expressions, the asymptotic ST and the asymptotic COP under the condition of high signal-to-noise ratio are also considered. Finally, all the derivations are validated by Monte Carlo simulations, and the effects of different parameters on the performance of the network are analyzed.
