“…The complete and incomplete low-bit-rate channel models were investigated for hybrid PLC/RF systems [30].

Hybrid power line communication (PLC) / visible light communication (VLC) networks have been demonstrated to be crucial for indoor practical communications and have attracted widespread attention. However, most current research in hybrid PLC/VLC networks focus mainly on communication reliability and resource allocation, and little has been carried on physical layer security. In this paper, we investigate the secure communication of a hybrid PLC/VLC network with two non-orthogonal multiple access legitimate users. During the two-hop PLC and VLC transmission, two eavesdroppers attempt to wiretap the confidential information from the PLC link via power line, and from the VLC link via visible light, respectively. Based on the randomness of the impulsive noise arriving at the PLC link, and the randomness of users' positions covered by the VLC link, the channel statistical characteristics of the PLC and VLC links are derived, respectively. Furthermore, the approximate closed-form expressions of secrecy outage probability (SOP) are determined. Simulations are performed to validate the effectiveness of theoretical results, and simulation results show that to get a high-level secrecy outage performance, the parameters of both the PLC and VLC links should be jointly designed. Furthermore, with regard to SOP, it is the worst case for both the PLC and VLC links eavesdropping, as compared to only PLC link eavesdropping or only VLC link eavesdropping.

“…Based on time-domain channel impulse response (CIR) modeling, the ergodic achievable secrecy rate and secrecy outage probability were numerically evaluated with the use of a dataset [17,18] obtained from a measurement campaign involving an impulsive noise-added communications system. Further, the effective secrecy throughput and wiretap code rates have been analyzed for wireless communication systems with pulse interference under the presence of colluding eavesdroppers in [19]. In [20], a novel CIR-based multilevel quantization was proposed to improve PLS by reducing the error mismatch rate.…”

As one of the main candidates for future civil aviation communications systems, the L-band digital aeronautical communication system (L-DACS) is expected to achieve secure and reliable transmission. Due to the broadcasting nature of air–ground wireless links, the L-DACS has the risk of being intercepted by malicious eavesdroppers, which negatively affects aviation communication security. In addition, because the spectrum of the L-DACS overlaps with the aviation distance measuring equipment (DME), the pulse interference caused by the DME signal may lead to the wireless link being more fragile and susceptible to wiretapping. In this paper, with a focus on enhancing wireless transmission security, we propose a comprehensive physical layer security (PLS) method for the L-DACS. The key to the proposed PLS method is restraining the transmission of the eavesdropper by injecting artificial noise into the transmitted signal while improving the transmission of the legitimate receiver through the adoption of pulse interference mitigation. First, to characterize the L-DACS in the secure scene, we derive the signal-to-interference-plus-noise ratio (SINR) of the legitimate receiver and any potential eavesdropper by constructing equivalent noise. Next, from the perspective of the information theory, we derive the closed form of the secrecy capacity of the L-DACS by employing the proposed PLS methods with three kinds of nonlinear interference mitigation: including ideal pulse blanking, peak threshold-based pulse blanking, and peak threshold-based pulse clipping. Finally, we compare and analyze different ways to enhance the secrecy capacity of the proposed PLS method using various interference mitigation methods.

Enhancing information security has become increasingly significant in the digital age. This paper investigates the concept of physical layer security (PLS) within a relay-aided power line communication (PLC) system operating over a multiple-input multiple-output (MIMO) channel based on MK model. Specifically, we examine the transmission of confidential signals between a source and a distant destination while accounting for the presence of multiple eavesdroppers, both colluding and non-colluding. We propose a two-phase jamming scheme that leverages a full-duplex (FD) amplify-and-forward (AF) relay to address this challenge. Our primary objective is to maximize the secrecy rate, which necessitates the optimization of the jamming precoding and transmitting precoding matrices at both the source and the relay while adhering to transmit power constraints. We present a formulation of this problem and demonstrate that it can be efficiently solved using an effective block coordinate descent (BCD) algorithm. Simulation results are conducted to validate the convergence and performance of the proposed algorithm. These findings confirm the effectiveness of our approach. Furthermore, the numerical analysis reveals that our proposed algorithm surpasses traditional schemes that lack jamming to achieve higher secrecy rates. As a result, the proposed algorithm offers the benefit of guaranteeing secure communications in a realistic channel model, even in scenarios involving colluding eavesdroppers.
