“…The aforementioned performance metrics are based on the first-order statistics, however, incorporating the second-order statistics in the secrecy performance metrics offers a better understanding of the dynamics of the performance. Two secrecy performance metrics that fall under this category were proposed in [22]. Namely, the average secrecy outage rate (ASOR) and the average secrecy outage duration (ASOD).…”

With the emergence of the internet of things (IoT) technology, wireless connectivity should be more ubiquitous than ever. In fact, the availability of wireless connection everywhere comes with security threats that, unfortunately, cannot be handled by conventional cryptographic solutions alone, especially in heterogeneous and decentralized future wireless networks. In general, physical layer security (PLS) helps in bridging this gap by taking advantage of the fading propagation channel. Moreover, the adoption of reconfigurable intelligent surfaces (RIS) in wireless networks makes the PLS techniques more efficient by involving the channel into the design loop. In this paper, we conduct a comprehensive literature review on the RIS-assisted PLS for future wireless communications. We start by introducing the basic concepts of RISs and their different applications in wireless communication networks and the most common PLS performance metrics. Then, we focus on the review and classification of RIS-assisted PLS applications, exhibiting multiple scenarios, system models, objectives, and methodologies. In fact, most of the works in this field formulate an optimization problem to maximize the secrecy rate (SR) or secrecy capacity (SC) at a legitimate user by jointly optimizing the beamformer at the transmitter and the RIS's coefficients, while the differences are in the adopted methodology to optimally/sub-optimally approach the solution. We finalize this survey by presenting some insightful recommendations and suggesting open problems for future research extensions.

“…PHY-security, due to its appealing advantages, has been widely investigated in the literature ( [7][8][9][10][11][12][13][14][15] and the references therein). However, all these works are limited to the scenario, where nodes in the network are stationary and the channel between them is modelled as either classical Rayleigh fading [7][8][9][10][11][12] or Nakagami-m fading [13][14][15], whereas, vehicular networks involve vehicle-to-vehicle (V2V) links (i.e. when both transmitter and receiver are in motion), and the channel between two mobile nodes can be modelled as cascaded Rayleigh or cascaded Nakagami-m fading, since it can appropriately capture the probabilistic channel effects [16,17].…”

“…For Rayleigh fading channels, the average secrecy capacity and secrecy outage performance for frequency diverse array communications were investigated in [ 7 ]. In [ 8 ], the average secrecy outage probability (SOP) and the average secrecy outage duration of Nakagami-m fading channel were discussed. Under generalized Gamma fading channels, the theoretical expressions of the probability of strictly positive secrecy capacity (SPSC) and the SOP were derived in [ 9 ].…”

In this paper, the physical layer security over the M-distributed fading channel is investigated. Initially, an exact expression of secrecy outage probability (SOP) is derived, which has an integral term. To get a closed-form expression, a lower bound of SOP is obtained. After that, the exact expression for the probability of strictly positive secrecy capacity (SPSC) is derived, which is in closed-form. Finally, an exact expression of ergodic secrecy capacity (ESC) is derived, which has two integral terms. To reduce its computational complexity, a closed-from expression for the lower bound of ESC is obtained. As special cases of M-distributed fading channels, the secure performance of the K, exponential, and Gamma-Gamma fading channels are also derived, respectively. Numerical results show that all theoretical results match well with Monte-Carlo simulation results. Specifically, when the average signal-to-noise ratio of main channel is larger than 40 dB, the relative errors for the lower bound of SOP, the probability of SPSC, and the lower bound of ESC are less than 1.936%, 6.753%, and 1.845%, respectively. This indicates that the derived theoretical expressions can be directly used to evaluate system performance without time-consuming simulations. Moreover, the derived results regarding parameters that influence the secrecy performance will enable system designers to quickly determine the optimal available parameter choices when facing different security risks.
