“…Since the COP expression derived in ( 14) is complicated, it is necessary to perform asymptotic analysis of the system at high SNR assuming 𝛾̅ 𝑆𝐷 → ∞ in order to understand the system performance. At high SNR, the asymptotic expression for the S-to-D CDF in ( 16) can be defined as [26]: (16) by putting ( 16) and ( 9) into ( 13), then the COP asymptotic expression can then be expressed as:…”

This paper evaluates the physical layer security performance of a reconfigurable intelligent surface (RIS) enabled wireless network in the presence of a passive eavesdropper. To secure the information transmission, a cooperative jammer is proposed to generate interference signal that degrade the performance of the eavesdropper. The source-to-RIS and RIS-to-destination links are subjected to Rician and Rayliegh fading distributions with phase errors, respectively, while other transmission links in the network follow the Nakagami-m fading distributions. The system phase error of the RIS is estimated by the von Mises distribution. To quantify the secrecy performance of the concerned system, the exact closed-form expressions in terms of connection outage probability (COP), security outage probability (SOP), and secrecy throughput (ST) are derived. In addition, the asymptotic expression of the system COP is obtained at high signal-to-noise ratio (SNR), providing more insight about the system performance. The accuracy of the derived expression is justified by Monte Carlo simulation. Also, the results clarify the analysis of the security performance, taking into account the impact of system and channel parameters on the system.

This article studies a smart grid dynamic wide area network where a friendly jammer is proposed to enhance the secrecy of the network. In the network, the smart meter (SM) in each household communicates with the full-duplex meter data control unit (FD-MDCU) via a decode-and-forward data aggregation unit in the presence of an eavesdropper. To improve the security of the network, the FD-MDCU transmits jammer signal which interfere with the eavesdropper. It is assumed that all the household are not sending data at the same time, thus Markov chain is employed to model the number of active SM. Thus, to evaluate the performance of the proposed network, the closed-form expressions of connection outage probability (COP), security outage probability, and secrecy throughput metrics are obtained. Moreover, more insight about the network performance is provide by obtaining the COP asymptotic expression at high signal-to-noise ratio. Also, the accuracy of the derived expressions is justified by Monte-Carlo simulations. Our findings demonstrate the impact of network and channel parameters on the network security performance.

The satellite-terrestrial downlink transmissions with larger coverage areas face more severe security challenges than terrestrial cellular communications due to the limitation of the satellite's power and the complexity of the channel. In this paper, the system model consists of one satellite, one legitimate user and multiple randomly distributed eavesdroppers while taking into account practical hardware impairments (HIs) at all transceivers involved. The Shadowed-Rician fading model is adopted since it is a perfect fit for the satellite-terrestrial channel.Besides, the full-duplex (FD) operation is introduced in the destination where the receiver acquires the information signal and simultaneously emits the artificial noise (AN) to interfere with the nearby eavesdroppers. The maximal ratio combination scheme is applied to the destination to improve security. To facilitate evaluation of the effect of various parameters on the security performance, the closed-form expressions of secrecy outage probability and ergodic secrecy capacity for the system are derived under the stochastic geometry framework.Finally, the simulation results show that the AN plays a pivotal role in improving the security performance, while the HIs can greatly deteriorate the performance, especially in the high transmit power regime. In addition, compared with the traditional half-duplex receiver, the FD receiver have better security performance and can significantly alleviate the performance deterioration caused by HIs.
