On the physical layer security over Beaulieu-Xie fading channel

Abstract

With the expansion of IoT and device-to-device communication applications, the security and privacy of the information have been kept at the forefront. The existence of a secondary eavesdropper, which attempts to access the confidential information of the legitimate partners, makes the data communication insecure. In this regard, we study the effect of randomness caused by the Beaulieu-Xie fading channel on the performance of physical layer security. To this end, the analysis for the secrecy outage probability (SOP) and average secrecy capacity (ASC) is carried out. Further, we derived the closed-form expressions for lower-bound of secrecy outage probability and strictly positive secrecy capacity (SPSC) for the said channel. To get more insight into the system, the high-power and low-power analysis of the ASC are also provided. Besides, the impact of different fading parameters on the system matrices is also investigated. Finally, the theoretical results are verified via extensive Monte Carlo simulations.
