“…Each relay has a single antenna while each destination receiver and each eavesdropper are equipped with G Q and G W antennas, respectively. In this particular communication scenario, we assume similar to [38] that the distances of Q and W from S are too large and due to masking effect, and severe shadowing there are no direct communication paths between S to Q as well as S to W. Hence the only communication path that exists is through the relay. The overall process is performed in two phases.…”

“…Due to this wide acceptance of wireless multicasting, novel researches are underway to enhance the secrecy performance. Physical layer security (PLS) of a multicasting scenario was analyzed in [37] and [38] over quasi-static Rayleigh fading and generalized κ − µ fading channels, respectively. In both papers, the authors derived the expressions of the probability of non-zero secrecy multicast capacity (PNSMC) and secure outage probability for multicasting (SOPM), though the authors in [38] considered a multiple relay system with the best relay selection scheme.…”

The secrecy of wireless multicast networks is greatly hampered due to the simultaneous presence of fading and shadowing, which can be enhanced using random attributes of the propagation medium. This work focuses on utilizing those attributes to enhance the physical layer security (PHY security) performance of a dual-hop wireless multicast network over κ − µ shadowed fading channel under the wiretapping attempts of multiple eavesdroppers. In order to raise the secrecy level, we employ multiple relays with the best relay selection strategy. Performance analysis has been carried out based on the mathematical modeling in terms of closed-form expressions of the probability of non-zero secrecy multicast capacity, secure outage probability for multicasting, and ergodic secrecy multicast capacity. Capitalizing on those expressions, we analyze how the system parameters (i.e. fading, shadowing, the number of antennas, destination receivers, eavesdroppers, and relays) affect the secrecy performance. Our numerical results show that the detrimental impacts due to fading and shadowing can be remarkably mitigated using the well-known opportunistic relaying technique. Moreover, the proposed model unifies secrecy analysis of several classical models, thereby exhibits enormous versatility than the existing works. Finally, all the numerical results are authenticated utilizing Monte-Carlo simulations.

The use of wireless transmission networks in various environments has become widespread. One of the main challenges in wireless networks is that the wireless transmission is highly vulnerable to eavesdropping attacks. In this paper, an amplifyand-forward cooperative relaying wireless system with relay selection is considered to improve the physical layer (PHY) security of the wireless system in the presence of multiple eavesdroppers, under two cases, namely, perfect channel state information (CSI) and outdated CSI cases. To evaluate the PHY security of the system, we derive closed-form expressions for the PHY security performance metrics, including the probability of non-zero secrecy capacity, the average secrecy capacity, and the secrecy outage probability. Then using those expressions, we obtain several numerical results under system parameters. The results show that relay selection provides significant improvement in the PHY security of the system. Moreover, it is observed that, when the CSI used to select the best relay is outdated, the PHY secrecy performance is relatively inferior compared to that of the perfect CSI case. Finally, the obtained mathematical expressions are also validated using Monte-Carlo simulation.
