Abstract

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.

Secrecy performance analysis of single-input multiple-output generalized-K fading channels

Hongjiang Lei, Imran Shafique Ansari, Chao Gao +3 more

In this paper, the transmission of confidential messages through single-input multiple-output (SIMO) independent and identically generalized- K ( K G ) fading channels is considered, where the eavesdropper overhears the transmission from the transmitter to the receiver. Both the receiver and the eavesdropper are equipped with multiple antennas, and both active and passive eavesdroppings are considered where the channel state information of the eavesdropper’s channel is or is not available at the transmitter. The secrecy performance of SIMO K G systems is investigated. Analytical expressions for secrecy outage probability and average secrecy capacity of SIMO systems are derived via two different methods, in which K G distribution is approximated by the Gamma and mixture Gamma distributions, respectively. Numerical results are presented and verified via the Monte-Carlo simulation.

On the Secrecy Performance Analysis of SIMO Systems Over $\kappa$ – $\mu$ Fading Channels

Jules Merlin Moualeu, Walaa Hamouda

In this letter, the secrecy performance of single-input multiple-output systems over the generalized$\kappa$–$\mu$fading channels is analyzed. Novel expressions for the average secrecy capacity and the secure outage probability (SOP) are derived. Moreover, simple and explicit expressions of the asymptotic SOP at high signal-to-noise ratio are given in an effort to gain some valuable insights on how various system parameters affect the secrecy performance. The proposed mathematical analysis is compared with Monte–Carlo simulation to verify the accuracy of the derivation.

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.

On the Secrecy Mutual Information of Nakagami-m Fading SIMO Channel

M. Z. I. Sarkar, Tharmalingam Ratnarajah

In this paper, we consider the transmission of confidential message through non-identically and identically independent Nakagami-m fading single-input multiple-output (SIMO) channel in the presence of an eavesdropper. We are interested in protecting this message against eavesdropping i.e. the information is secure if it cannot be eavesdropped by any eavesdropper. Based on the problem of secure communications between transmitter and intended receiver over Nakagami-m fading channel where an eavesdropper observes their transmissions through another Nakagami-m fading channel, we derive the analytical expressions for the probability of non-zero secrecy mutual information, secure outage probability and ergodic secrecy mutual information of SIMO wireless communication systems over non-identically and identically independent Nakagami-m fading subchannels. Numerical results are presented and verified via Monte-Carlo simulation.

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.
