Abstract

We assume a full-duplex (FD) cooperative network subject to hostile attacks and undergoing composite fading channels. We focus on two scenarios: a) the transmitter has full CSI, for which we derive closed-form expressions for the average secrecy rate; and b) the transmitter only knows the CSI of the legitimate nodes, for which we obtain closed-form expressions for the secrecy outage probability. We show that secure FD relaying is feasible, even under strong self-interference and in the presence of sophisticated multiple antenna eavesdropper.

Artificial Noise Aided Precoding With Imperfect CSI in Full-Duplex Relaying Secure Communications

Yuanjian Li, Rui Zhao, Yi Wang +2 more

In Rayleigh fading channels, to enhance the secrecy performance of wireless communication systems and efficiently disturb the interception of eavesdroppers, the multiple-antenna source node utilizes the artificial noise aided precoding (ANP) strategy with imperfect channel state information to emit the confidential information and the artificial noise simultaneously. Besides, the two-antenna decode-and-forward relay node applies the full-duplex (FD) relaying protocol, and the destination node which contains multiple antennas adopts the maximum ratio combining technique. Taking into account the existence of self-interference at the relay, the closed-form expression of approximate ergodic achievable secrecy rate (EASR) for any value of antenna number and that of exact EASR in the case of large-scale antenna array are derived, respectively. To extract more distinct insights from the considered system and hence obtain some simple and meaningful conclusions, the asymptotic performance analyses in two different asymptotic cases are studied. The numerical simulations validate the correctness of our theoretical derivation and analysis, which indicates that the ANP scheme combined with the FD relaying can achieve considerable secrecy performance.

On the performance of full-duplex relaying under phy security constraints

Hirley Alves, Glauber Gomes de Oliveira Brante, Richard Demo Souza +2 more

In this paper we investigate the performance of a cooperative network in the presence of an eavesdropper (Eve). Alice and Bob communicate with the help of a relay, which can operate either in half-duplex (HD) or full-duplex (FD) mode. We account for the self interference at the relay when operating under FD mode. Our analysis focus in the case that the CSI of Eve is not available at Alice. Thus, we derive closed-form expressions for secrecy outage probability. Our results allow us to compare the performance of FD and HD cooperative scenarios under secrecy constraints and, despite the additional interference at the relay, show the advantages of FD relaying over HD. In addition, we also show that a cooperative network is more vulnerable if Eve is closer to Alice than to the relay.

Secrecy rate with friendly full-duplex relay

Saeedeh Parsaeefard, Tho Le‐Ngoc

This paper considers the use of a friendly full-duplex (FD) relay to increase the secrecy rate over a fading channel between the legitimate source and destination in the presence of a naive or informed eavesdropper. Naive eavesdropper can only decode the received signals either from the source or from the relay, while informed eavesdropper can overhear signals transmitted from both the source and relay. Accordingly, we compare the achievable secrecy rates of FD relay with traditional half-duplex (HD) relay in terms of the channel state information (CSI) between nodes, eavesdropper types, and the self-interference (SI) in FD-Relay. We consider the non-convex power allocation problems for the developed FD-relay to maximize the secrecy rate under the power constraints and develop an efficient iterative algorithm based on the difference-of-two-concave-functions (DC) programming. The analytical and simulation results confirm that FD relay offers significant improvements in the secrecy rate over the HD-Relay.

Analyzing Secrecy Outage in Hybrid Full-Duplex Attack While Exploiting CSI of Legitimate Link

Bhawna Ahuja, Deepak Mishra, Ranjan Bose

The growing concern of secure communication becomes more challenging when encountering a hybrid Full-duplex (FD) attacker possessing the dual capability to perform eavesdropping and jamming simultaneously. To analyze secrecy outage performance in the presence of such a potential attacker, the proposed work assumes complete information of the legitimate link only. It considers unavailability of complete information of all the ungoverned communication links including eavesdropping, jamming and self-interference link of attacker. FD operation is associated with the problem of imperfect self-interference cancellation. Our proposed analysis considers residual self-interference at the attacker's end in its modelling. The closed-form expressions have been obtained for secrecy outage probability under generalized as well as special cases. The results obtained facilitate in investigating the impact of fading under FD attack and provide important insights about source power, jamming power, attacker's location. Approximate closed-form results also help in reducing computation time by more than 55%.

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.
