Abstract

In this paper, a single input single output (SISO) scheme is proposed to analyze the security in Generalized Gamma (GG) fading channels with dual-branch selection diversity receiver in the presence of numerous eavesdroppers. The primary objective of this paper is to analyze the effects of shaping parameters ω and β with $\mathcal{S}$ number of eavesdroppers on the secrecy performance of the proposed scheme. The closed-form analytical expressions of the probability of non-zero secrecy capacity (PNZSC) and the secure outage probability (SOP) have been derived and verified with the simulation one. Our results revealed that the secrecy performance degrades with increasing in the shaping parameters related to eavesdroppers as well as increasing in the number of eavesdroppers whereas upgrades with increasing in the shaping parameter of the main channel.

Security Analysis in Multicast Networks over Generalized Gamma Fading Channels Operating Dual-Branch Diversity Receiver

A. H. M. Zahirul Alam, M. Z. I. Sarkar, M. R. A. Ruku +2 more

In this paper, a single input multiple output (SIMO) multicasting network scheme is proposed over generalized gamma fading channels with dual-branch diversity receivers in the presence of multiple eavesdroppers. The main goal of this paper is to analyze the effects of shaping parameters$\omega$and$\beta$with a number of$\theta$receivers and$\phi$eavesdroppers on the secrecy performance of the proposed scheme. The closed-form analytical expressions of the probability of non-zero secrecy multicast capacity (PNZSMC) and the secure outage probability for multicasting (SOPM) have been derived and verified via the monte carlo simulation. Our results revealed that the secrecy performance degrades with increasing in the shaping parameters related to eavesdropper and upgrades with increasing in the main channel shaping parameter. Secrecy performance is also greatly affected by the number of receivers and eavesdroppers. Increasing in the number of receivers and eavesdroppers, the secrecy performance degrades.

Average secrecy rate and probability of non-zero secrecy capacity of wiretap generalised gamma fading channels

Sandeep Kumar Singh, Gaurav Kumar Verma, Anshul Singh +2 more

In this paper, secrecy performance is studied for the classic Wyner's wiretap channel which follows Generalised Gamma (GG) distribution. In order to evaluate the secrecy performance, we derived the exact Average Secrecy Rate (ASR) and closed form expression for the Probability of Non-Zero Secrecy Capacity (PNZSC) for different fading parameters corresponding to main and eavesdropper's channels. The results are then simulated and verified. It has been observed that the ASR of GG fading increases with the increase in the fading constant of the main channel.

Secure Wireless Multicasting with Mixture Gamma Distribution for Generalized-K Fading Channels

Milton Kumar Kundu, M. Z. I. Sarkar, A. S. M. Badrudduza +1 more

This paper concentrates on the analysis of security performance for transmitting confidential data from a source to multiple receivers over Generalized-K fading multicasting channel in the presence of multiple eavesdroppers. All the terminals are equipped with single antenna and all the channels are Generalized-K fading based on mixture gamma distribution. In order to investigate the effects of fading parameters imposed on the Generalized-K fading with mixture gamma distribution, we derive the closed-form analytical expressions for the probability of non-zero secrecy multicast capacity, ergodic secrecy multicast capacity and the secure outage probability for multicasting &. The derived analytical expressions are presented in terms of the fading parameters of Generalized-K fading with mixture gamma distribution so that they are helpful to understand the insight, how the security in multicasting can be enhanced adjusting the parameters of Generalized-K fading channels. Monte-Carlo Simulations have also been performed to validate the analytical results.

Hongjiang Lei, Imran Shafique Ansari, Huan Zhang +2 more

In this work, we consider the transmission of confidential message through independent and identically distributed generalized-K fading single-input multiple-output (SIMO) channels in the presence of an eavesdropper. The security performance of SIMO generalized-K systems are investigated using a mixture gamma (MG) distribution, and the analytical expressions for the average secrecy capacity (ASC) and the secure outage probability (SOP) of SIMO systems are derived. Numerical results are presented and verified via Monte-Carlo simulations.

Performance Analysis of Physical Layer Security over Rician/Nakagami-m Fading Channels

Shunya Iwata, Tomoaki Otsuki Ohtsuki, Pooi‐Yuen Kam

In this paper, we investigate the secrecy performance of single-input single-output (SISO) system over fading, such that the main channel and the eavesdropper channel are subject to Rician/Nakagami-m fading or Nakagami-m/Rician fading, and derive the analytical expressions of the probability of the existence of the non-zero secrecy capacity and the outage probability of secrecy capacity. Although many authors have analyzed the secrecy performance of SISO system over various fading, the secrecy performance in the cases we assume has not been clarified. Furthermore, the simulation and numerical results show that the results using the approximation between Rician and Nakagami-m fading is insufficient in evaluating those probabilities because of only approximation to main bodies of the probability density function, and that our analyses are valid.
