“…The reliability of the system is quantified by COP which describes the probability of the connection outage event in which the destination SNR is less than the preset threshold value 𝛾 𝑡 = 2 𝑅 𝑡 − 1 with 𝑅 𝑡 (𝑏𝑖𝑡𝑠/𝑠/𝐻𝑧) denotes as transmit rate. Thus, the COP of the concerned system can be expressed as [25]:…”

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.

“…In recent years, simultaneous wireless information and power transfer (SWIPT) has attracted an increasing attention of researchers, which transmits information and energy to destinations simultaneously [4,5]. There are two protocols for SWIPT, namely time-switching scheme (TS) and power-splitting scheme (PS) [6,7]. Specifically, PS protocol divides the received RF signals into two parts, one for energy harvesting and the remaining for information processing.…”

In this paper, the secrecy performance in a MIMO cognitive radio (CR) relay network with energy harvesting (EH) and transmit antenna selection/maximal ratio combining (TAS/MRC) is invstigated, where the DF relaying protocol and multiple colluding passive eavesdroppers are considered. To improve the security of wireless transmission, two antenna selection schemes are proposed, namely, the optimal transmit antenna selection (OTAS) scheme and suboptimal transmit antenna selection (STAS) scheme. For the purpose of comparison, the space‐time transmission (STT) scheme is introduced as a baseline. The exact and asymptotic closed‐form secrecy outage probability (SOP) expressions for OTAS, STAS and STT schemes are derived over Rayleigh fading channels. An extension of the TAS framework to an artificial noise (AN) aided MIMO network is further presented and an AN aided transmit antenna selection (AN‐TAS) scheme is proposed, in which the unselected antennas at R are used to emit AN for interfering with Es. Numerical results show that the OTAS and STAS schemes perform better than STT scheme in terms of SOP. Meanwhile, the SOP of AN‐TAS scheme is much smaller than that of OTAS, STAS and STT schemes in the high SNR region, indicating the benefit of applying AN in MIMO network.
