“…By considering the impact of IQI, the papers [34] and [35] analyze the security and reliability performances of cooperative dual-hope NOMA and the ambient backscatter NOMA, respectively. Further, a security analysis of relaying NOMA based on Beaulieu-Xiefading channels and IQI is presented in [36]. The studies [34], [35], [36] indicate that IQI decreases reliability and increases the security of NOMA.…”

This study proposes a novel secure uplink index modulation-based orthogonal frequency division multiple access (IM-OFDMA) systems using artificial in-phase and quadrature imbalance (A-IQI). The fact of the distinct A-IQI induced at the users' end and the unpredictable allocation of users based on confidential data brings a different perspective on physical layer security. Accordingly, in this study, the non-identical effect of A-IQI is exploited to provide a physical-layer security scheme for the IM-OFDMA systems. Specifically, the estimation method is created with preamble data in order to achieve each user's unique A-IQI information from a legitimate receiver. The A-IQI will help to secure the transmitted data against a potential eavesdropper, and hence, improving data confidentiality. The proposed scheme's performance is analytically evaluated by deriving closed-form expressions of the average bit error rate (BER) at both the base station and the eavesdropper. The image rejection ratios of A-IQI and practical IQI are provided for IM-OFDMA to indicate the region of intentionally generated A-IQI. Under the different system model specifications of IM-OFDMA, the analytical results are provided with simulation results obtained using the Monte Carlo simulation method. Further, the proposed secure scheme is compared with the stateof-the-art artificial noise method. Results reveal a significant improvement in the BER at the base station, accompanied by severe degradation in the BER at the eavesdropper.

“…The acceleration state and operation characteristics are the vital functions of relay protection devices in industrial systems. By monitoring the operation state of the electrical system, the relay protection device can detect faults and abnormal situations in time and take corresponding protective measures to ensure the stable operation of the power system [1]. However, the protection device may also suffer from failure or aging, resulting in its performance degradation or even failure [2].…”

“…Dedicated relaying with the Amplify and Forwards (AF) and Decode and Forwards (DF) protocols in half-duplex and full-duplex modes cooperative approaches are used with NOMA [15]. Also, the NOMA technology may successfully decrease the system latency by removing the scheduling [16]. In the network, independent non-selective Rayleigh fading is used to mimic each wireless link.…”

Cooperative Non‐orthogonal Multiple Access (C‐NOMA) is projected as the dominant technology for 5G and beyond. Also, physical layer security, due to the presence of eaves‐dropper, is a bottleneck security concern for any open link wireless system. This manuscript presents a novel Decode & Forward (DF)‐based C‐NOMA system in the presence of two eavesdroppers. Moreover, both half duplex and full duplex schemes are included in the analysis. Thereby, separate expressions for Secrecy Outage Probability (SOP), being among the most crucial performance measures in physical layer security, are produced and examined for the system under consideration. Specifically, first of all, novel expression of SOP for C‐NOMA systems under both Half Duplex (HD) and Full Duplex (FD) schemes is derived for the case when only eavesdropper one (E1) attacks on link source to device one (S‐D1). Thereafter, expressions of SOP for the C‐NOMA system under both HD and FD schemes are derived, considering presence of E1 and E2 on the links, source to device one (S‐D1) and source to device two (S‐D2), respectively. Further, for both the duplexes, the effect of eavesdropper one (E1) and eavesdropper two (E2) on the links, S‐D1 and S‐D2, respectively, is analyzed. The presented analysis is useful in the technological development level of C‐NOMA in the presence of multiple eavesdroppers. The simulated results show perfect agreement with the theory.
