Abstract

In this letter, we study the secrecy performance of the classic Wyner's wiretap model, where the main and eavesdropper channels are modeled by a general and versatile α-η-κ-μ fading model. Novel and exact expressions of the average secrecy capacity and secrecy outage probability have been derived. Previous results on physical layer security can be obtained through our newly derived expressions by specializing the model parameters. More importantly, the derived results are also applicable for the secrecy performance analysis of some field measurements (e.g., in millimeter wave communications), which cannot be analyzed by previous results.

Secrecy Performance of Correlated $\alpha$ -$\mu$ Fading Channels

Aashish Mathur, Yun Ai, Michael Cheffena +1 more

This letter investigates the secrecy performance of the classical Wyner's wiretap model, where the main channel and eavesdropper channel experience correlated α-μ fading. Novel and exact expressions for the average secrecy capacity and secrecy outage probability are derived for the considered realistic scenario. The effect of correlation has been studied on the secrecy performance. Useful insights into the system performance are obtained through the asymptotic analysis.

Performance analysis of physical layer security over α-η-κ-μ fading channels

Shaobo Jia, Jiayan Zhang, Honglin Zhao +1 more

In this paper, we consider the secure data transmission over α-η-κ-μ fading channels, which are recently proposed to encompass nearly all the well-known statistical models adopted in the literature. In particular, we address the secrecy performance in terms of the average secrecy capacity (ASC) and the secrecy outage probability (SOP), for which novel analytical expressions are derived. Simulation results verify the analysis and demonstrate the impact of the physical parameters on the secrecy performance of this new channel fading model.

Secrecy outage probability and intercept probability analysis over α-F fading channels

Jelena A. Anastasov, Aleksandra S. Panajotović, Nikola Sekulović +2 more

In this paper, we investigated the secrecy performance of traditional Wyner's wiretap model over α-F fading channels. The expressions for evaluating the secrecy outage probability and the probability of intercept are derived. Due to high generality of assumed fading model which includes other models as special or limiting cases, presented analysis is quite general. Based on obtained analytical results, the impact of fading depth and shadowing severity of main/wiretap channel on the physical layer security metrics is studied. The results showed that secrecy transmission can be enhanced by proper exploiting propagation characteristics of authorized/unauthorized wireless channels.

Performance Analysis of Physical Layer Security Over Generalized-$K$ Fading Channels Using a Mixture Gamma Distribution

Hongjiang Lei, Huan Zhang, Imran Shafique Ansari +4 more

In this letter, the secrecy performance of the classic Wyner's wiretap model over generalized-K fading channels is studied. The closed-form expressions for the average secrecy capacity, secure outage probability, and the probability of strictly positive secrecy capacity are derived. The new expressions provide a unified form, which can handle several of the well-known composite fading environments as special or limiting cases. Monte-Carlo simulations are performed to verify the proposed analysis models.

Secrecy Capacity of Physical Layer over $\kappa-\mu$ /Gamma Composite Fading Channel

Rupender Singh, Meenakshi Rawat

Rapid developments of the emerging wireless network applications such as 5G, IoT and device-to-device (D2D) systems raise the diversity of challenges in physical layer security (PLS). In the present work, we examine Wyner's wiretap composite multipath/shadowing fading channel model and provide analysis for PLS secrecy performance. We consider a generic single-input and single-output (SISO) system where both the main and eavesdropper channels are modeled by κ-μ /gamma composite fading channel. In particular, the lower bound of secure outage probability (SOPL) and strictly positive secrecy capacity (SPSC) are obtained in closed-form. We also conduct the analysis for average secrecy capacity (ASC) in heavy shadowing and derive analytical expression in closed-form.
