Abstract

In this paper, we consider the transmission of confidential message through single-input-multiple-output (SIMO) identically and independent generalized-K fading channels in the presence of an eavesdropper. We derive the analytical expressions for the probability of strictly positive secrecy capacity (SPSC), secure outage probability (SOP), and average secrecy capacity (ASC) of SIMO systems. Numerical results are presented and verified via Monte Carlo simulation.

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.

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.

The Performance of Physical Layer Security over $K$ Fading SIMO Channel

Linna Zhou, Yang Cao

The wireless communication services are developing rapidly, but the vulnerability of its broadcast is often eavesdropped and attacked by an illegal third party, which poses a huge challenge for secure transmission. Traditional upper-layer protocols and tools have inherent loopholes and difficulties in key distribution and management. However physical layer security technology has become an important technology to the assurance of information security by its simple algorithms and better practicability. In this paper, based on the secure performance of single-input multiple-out (SIMO) Wyner's wiretap model over K fading channels, the closed-form expressions for average secrecy capacity (ASC), secure outage probability (SOP) and the probability of strictly positive secrecy capacity (SPSC) are derived. The theoretical analysis and Monte Carlo simulation prove that the results are consistent and feasible, with an important role in restraining illegal interception and attack.

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.

Secrecy Performance Analysis of SIMO Systems Over Correlated $\kappa$ –$\mu$ Shadowed Fading Channels

Jiangfeng Sun, Hongxia Bie, Xingwang Li +3 more

In this paper, the secrecy performance of single-input-multiple-output systems over correlated κ-μ shadowed fading channels is investigated. In particular, based on the classic Wyner's wiretap model, we derive analytical expressions for secure outage probability (SOP) and the probability of strictly positive secrecy capacity (SPSC) over correlated κ-μ shadowed fading channels. In order to further study the impact of channel parameters on the secrecy performance, novel SOP and the probability of SPSC over independent and identically distributed κ-μ shadowed fading channels are also obtained. In addition, we discuss the asymptotic expressions of the SOP and the SPSC. The match between the analytical results and simulations is excellent for all parameters under considerations. It is interesting to find that the results show that when the signal-to-noise ratio of the main channel is lower than that of the eavesdropping channel, the larger value of correlation coefficient is helpful to improve the secrecy performance and vice versa.

Average Secrecy Capacity of SIMO k-μ Shadowed Fading Channels with Multiple Eavesdroppers

Jiangfeng Sun, Hongxia Bie, Xingwang Li +2 more

In this paper, we analyze the security capability of single-input multiple-output wireless transmission systems over k-μ shadowed fading channels in the presence of multiple eavesdroppers. Our security analysis relies on an important standard, i.e., average secrecy capacity which is more difficult and suitable for analyzing active eavesdropping scenario than secure outage probability and probability of strictly positive secrecy capacity. The novel expression of average secrecy capacity over k-μ shadowed fading channels with multiple eavesdroppers is deduced. The results of Monte Carlo simulation fully prove the correctness of our theoretical derivation. Through the obtained results, we observe that large antenna quantity in the highest signal-to-noise ratio regime, small number of the eavesdroppers, and small signal-to-noise-ratio of eavesdropping link will enhance confidentiality of the system under consideration.
