Abstract

The rapid development and popularization of wireless communications makes communication resources even more short and communication service face even bigger security threat. To improve the security and energy and spectrum efficiency, the research is focused on the communication system, which is composed of an information transmitter, a desired receiver, an eavesdropper and a full-duplex relay, Among those the relay node with energy harvesting capability works in full-duplex mode. Via building the system as flat Rayleigh fading model, the security performance of the system is analyzed, and the theoretical expression of security outage probability acquired.Finally, Monte Carlo simulation results verify the theoretical-analysis results, and indicate the effect of various parameters on the system performance.

Jammer against eavesdropper in half-duplex energy harvesting cooperative relaying networks: secrecy outage probability analysis

Phu Tran Tin, Duy-Hung Ha, Minh Hoang Quang Tran +1 more

In this paper, we have investigated the Half-Duplex (HD) Energy Harvesting (EH) Cooperative Relaying Networks with one source node, one destination node, one intermediate relay and in the presence of the Jammer Against Eavesdropper. We have analyzed the system performance in terms of the integral form expression of secrecy outage probability. In addition, we have investigated the effect of source rate, time switching factor, energy coefficient, and the ratio Ps/N0 on the system performance. Finally, all the mathematical, analytical expressions are verified by Monte Carlo simulation, and the analytical results match well with the simulation ones to convince the correctness of the analytical expression.

Physical layer security analysis for cooperative communication with full-duplex relaying under Nakagami-m fading model

Yohannes Jote Tolossa, Giuseppe Thadeu Freitas de Abreu

We characterised the physical layer security of a three terminal cooperative network with full-duplex relaying under Nakagami-m channel analytically and through simulation. An eavesdropper also coexists within the system at an arbitrary distance from the transmitter. Using secrecy outage probability as a metric to characterise the secrecy performance, integral expression for the corresponding outage probability of the relevant communication link is derived. Furthermore, the secrecy outage probability with half-duplex relay is also analysed. Simulation results show that cooperative communication with FD relay has less secrecy outage even with the presence of residual self-interference than HD relay.

Physical Layer Security Analysis of Cooperative Mobile Communication Systems with Eavesdropper Employing MRC

Semiha Koşu, Serdar Özgür Ata, Lütfiye Durak-Ata

In this paper, physical layer security (PLS) analysis of a cooperative wireless communication system in which the source and destination nodes communicate via a relay employing decode-and-forward protocol is performed for double Rayleigh fading channel model. For the system where the source, relay and target have single antenna, an eavesdropper with multiantenna listens the source and relay together by using maximum-ratio-combining, secrecy outage and positive secrecy capacity possibilities are obtained in closed-form. The theoretical results are verified by Monte-Carlo simulations. From the results, it is observed that as the number of antennas of the eavesdropper is increased, the PLS performance of the system worsens.

Improving Physical Layer Security of Cooperative NOMA System with Wireless-Powered Full-Duplex Relaying

Yuan Ren, Yixuan Tan, Meruyert Makhanbet +1 more

Non-orthogonal multiple access (NOMA) and wireless energy harvesting are two promising technologies for improving spectral efficiency and energy efficiency, respectively. In this paper, we study the physical layer security of a wireless-powered full-duplex (FD) relay-aided cooperative NOMA system. In particular, the source is wiretapped by an eavesdropper, and the FD relay assists the transmission from the source to a near user and a far user with self-energy recycling. To enhance the security performance of the system, we propose an artificial noise (AN)-aided cooperative transmission scheme, in which the relay emits a jamming signal to confuse the eavesdropper while receiving the signal from the source. For the proposed scheme, the ergodic secrecy sum rate (ESSR) is derived to characterize the secrecy performance and a lower bound of ESSR is obtained. Finally, numerical results verify the accuracy of the theoretical analysis of the proposed AN-aided secure transmission scheme. The superiority of the proposed scheme is also demonstrated since this scheme can achieve better secrecy performance, compared to the conventional cooperative NOMA scheme.

Physical layer security in DF full-duplex relaying network: performance analysis

Phu Tran Tin, Tan Nhat Nguyen, Van-Duc Phan +1 more

In this letter, the system performance of the DF full-duplex (FD) Relaying communication network is investigated with Physical Layer Security (PLS). In this system model, the source (S) and the destination (D) communicate via a helping relay (R) in the presence of the Eavesdropper (E). From the system model, we derive the closed-form expressions for Intercept Probability (IP) and secrecy outage probability (SOP). For verifying the correctness of the analytical analysis, the Monte Carlo simulation is conducted. In addition, the influence of the main system parameter on the system performance is investigated. Finally, the results show that the analytical and the simulation values agree well with each other.

Exact outage and intercept analysis of physical layer security in half-duplex energy harvesting relay systems

The-Anh Ngo, Xuan-Truong Tran, Viet-Thanh Le +2 more

This paper investigates physical layer security (PLS) in a half duplex (HD) relay network with radio frequency energy harvesting (EH). We consider an amplify and forward (AF) protocol in which both the source and the relay harvest energy from a dedicated power beacon, while a passive eavesdropper attempts to intercept the confidential message. Unlike prior studies that rely on asymptotic analysis or numerical integration, we derive exact closed form expressions for the outage probability (OP) and the intercept probability (IP). The proposed expressions characterize the reliability and secrecy trade-off in energy limited cooperative relaying and enable efficient performance evaluation. Monte Carlo simulations validate the analysis and match the theoretical results. Moreover, the closed form results reveal how channel conditions and harvesting duration jointly shape outage and interception behaviors. We further quantify the impacts of normalized transmit power, the time allocation factor between harvesting and information transmission, and the EH efficiency. The results provide practical guidance for selecting system parameters to meet target reliability and secrecy levels, and they show that the time allocation factor must be carefully chosen to balance harvested energy and transmission time.
