“…It is worth pointing out that, to ensure the jamming signal d k * can be subtracted by destination i * , it is necessary to take the additional operations (i.e., the pseudo-random code sharing between each destination but not opening to the untrusted relay [25], or random seeds sharing by utilizing the reciprocity of the channels [24], [31]). Meanwhile, the CSI between relay and destination k * should also be provided to the destination i * .…”

“…In [30], DBJ and precoding schemes have been jointly considered in MIMO untrusted relay networks. The authors in [31] analyze ergodic secrecy rate (ESR) for cooperative multicast networks, in which the energy harvesting destination nodes are considered. For multi-relay scenario, the lower bound of the ergodic secrecy capacity for a single source-destination pair is derived in [32].…”

This paper investigates the physical-layer security of an amplify-and-forward wireless cooperative network where N source nodes communicate with their corresponding destination nodes under the help of an untrusted relay. In each slot only one user-pair is scheduled to transmit the information, and the destination aided cooperative jamming is adopted to protect information from being intercepted by the untrusted relay. Three user-pair selection schemes have been proposed for the considered system, namely opportunistic user-pair selection (OUS) scheme, greedy user-pair selection (GUS) scheme and genie-aided user-pair selection (GAUS) scheme. Both the secrecy outage probability and average secrecy rate have been studied to evaluate the performance of the OUS and GUS schemes, and the asymptotic analysis has also been obtained. It reveals that, the proposed schemes can improve the secrecy performance for the cooperative multiuser networks as the number of user-pairs increases. We also prove that the achievable diversity order of both OUS scheme and GUS scheme is N 2. Finally, numerical and simulation results are presented to validate the accuracy of the developed analytical results.

“…In [15], the authors have studied the physical layer security in destination assisted jamming networks in which a selected destination sends jamming signal in the first time slot to an untrusted AF relay. In the same, destination harvests energy from the environment based on the Bernoulli process.…”

“…Literature [27] investigated the secrecy performance of a two-hop communication between a source and a destination using destination-assisted jamming, for the reason that the source used an AF wireless energyharvesting untrusted relay to forward the confidential information to the legitimate destination. References [28]- [31] combined cooperative jamming and energy-harvesting relay to improve the physical layer security performance. Reference [28] proposed an energy-harvesting destination aided cooperative jamming framework to protect enciphered information from being intercepted by the untrusted relay.…”

Security Performance Analysis for Best Relay Selection in Energy-Harvesting Cooperative Communication Networks

In this paper, we investigate an energy-harvesting cooperative communication network, which comprises of a source, a destination, and multiple decode-and-forward (DF) relays in the presence of multiple passive eavesdropper (Es). Es attempt to intercept confidential information transmissions from the source to destination via DF relays. In this network, all the DF relays harvest energy from radio-frequency (RF) signals of a source through time-switching receivers. In order to improve the physical layer security of energyharvesting cooperative communication networks, we propose a best relay selection (BRS) scheme, where the ''best'' relay is chosen to assist the source-destination transmission. For the purpose of comparison, we consider the classic direct transmission (DT) and equal relay selection (ERS) as benchmark schemes. We derive the exact closed-form expressions of outage probability (OP) and intercept probability (IP) for the ERS and BRS schemes over Rayleigh fading channels. Besides, the security-reliability tradeoff (SRT) is analyzed as a metric to evaluate the tradeoff performance of the proposed BRS scheme. Numerical results show that the SRT of the BRS scheme consistently outperforms that of the ERS scheme, which demonstrates the advantage of our proposed scheme against eavesdroppers. Besides, it is verified that total error rate (TER) defined as the sum of OP and IP can be minimized for both the ERS and BRS schemes through changing the time allocation factor between information transmission and energy harvesting phases. Moreover, there is a best energy conversation efficiency to obtain a maximal SRT value of the ERS and BRS schemes. In addition, as the number of DF relays increases, the SRT of BRS scheme improves notably, while that of ERS scheme remains unchanged. And as the number of Es increases, the SRT of both the ERS and BRS schemes become worse.
