Abstract

This paper investigates the secure transmission in simultaneous wireless information and power transfer (SWIPT) system, where a source node communicates with a wireless‐powered full duplex destination node in the presence of a passive eavesdropping node. To take advantage of the benefits from SWIPT and full duplex techniques, we propose a two‐phase time‐sharing protocol: the destination node harvests energy form the source node in the first phase, while the information‐bearing signal is transmitted under the protection of artificial noise sent from the destination node in the second phase. The transmit power of the artificial noise is converted from the harvested energy and self‐interference exists at the destination. We derive the closed‐form expressions for the connection outage probability (COP), the secrecy outage probability (SOP) and the transmission outage probability (TOP), based on which the secrecy energy efficiency (SEE) is formulated. Furthermore, we determine the optimal time allocation factor and transmission power that maximize the SEE while satisfying the COP and SOP constraints. Finally, numerical results verify our analytical results and show that there are tradeoffs among security, reliability and energy efficiency. When the residual loopback interference is mitigated under some certain level, our proposed optimization scheme can significantly boost the SEE.

This work investigates the secure transmission in the wireless information and power transfer system where a source node communicates with a wireless-powered full-duplex destination node in the presence of a passive eavesdropper. In particular, we propose such a two-phase time-sharing (TS) secure communication protocol: in the first phase, energy harvesting is conducted from the source node to the destination node, while in the second phase, the source node transmits information-bearing signal under the protection of artificial noise sent from the destination node. It is worth to mention that the energy of this artificial noise at the destination node is converted from the harvested energy in the first phase and self-interference exists at the destination in the second phase. We derive the closed-form expressions for the connection outage probability (COP), the secrecy outage probability (SOP) and the transmission outage probability (TOP), based on which the secrecy throughput is formulated. Further, we determine the optimal time allocation factor and the optimal codeword transmission rate to maximize the secrecy throughput with dual outage constraints. Finally, numerical results verifies our results and exams the effect of the time allocation factor and the codeword transmission rate on the performance.

Haoyuan Zhou, Weijia Lei

A secure transmission scheme of anti-eavesdropping on the physical layer in simultaneous wireless information and power transfer (SWIPT) is proposed. Each node in the system is a single-antenna node. There are direct links between eavesdropping node and the source or relay node. The relay work in a full-duplex mode, which uses the amplify-and-forward method to forward the signal. Between the source and relay node is SWIPT mode. The relay collects energy from the received radio frequency (RF) signal and uses it for forwarding. The destination node is also a full-duplex node, sends artificial noise to perform cooperative interference while receiving information to intercept the eavesdropping node. Aiming at maximizing the secrecy rate of the system, the power splitting factor, signal and artificial noise power distribution factor are optimized when the relay adopts the power splitting method. Simulation results suggest that the use of power splitting way and cooperative interference scheme at destination can significantly improve the performance of system.

Analysis of SWIPT-Enabled Relay Networks with Full-Duplex Destination-Aided Jamming

Jinglan Ou, Hangchuan Shi, Liubin Wang +2 more

Simultaneous wireless information and power transfer (SWIPT) is a major breakthrough in the field of low-power wireless information transmissions. In this paper, the secrecy performance of the SWIPT-enabled relay network with full-duplex destination-aided jamming is assessed, where both the power-splitting (PS) and time-switching (TS) schemes at the relay are considered with the linear and nonlinear energy harvesting models. The relay harvests energy from the confidential signal and artificial noise sent by the source and destination, respectively, and forwards the amplified signal to the destination, in the presence of an eavesdropper. The analytical closed-form expressions of the connection outage probability (COP), secrecy outage probability (SOP), and transmission outage probability (TOP) for PS- and TS-based schemes are derived, and the closed-form expression of the lower bound of ergodic secrecy capacity (ESC) is calculated. The asymptotic-form expressions of the COP, SOP, TOP, and ESC are further analyzed to capture the valuable information in the high SNR regime. Numerical results verify the correctness of analytical results, reveal the effects of the PS/TS ratio, and transmit the signal-to-noise ratio on secrecy performance.

Energy-Constrained SWIPT Networks: Enhancing Physical Layer Security With FD Self-Jamming

Xuanxuan Tang, Yueming Cai, Yansha Deng +3 more

In this paper, we investigate the secrecy performance of energy-constrained wireless-powered networks with considering the passive eavesdropping scenario, where the simultaneous wireless information and power transfer-based full-duplex self-jamming (SWIPT-FDSJ) scheme is developed. The maximal ratio transmission protocol is applied at the multi-antenna source such that the wireless signals are designated to the destination directly. Besides, the energy harvesting and full-duplex self-jamming operations are adopted at the energy-constrained destination to prolong its lifetime as well as to confuse the eavesdropper. Specifically, the exact and asymptotic closed-form expressions of the connection outage probability (COP), the secrecy outage probability (SOP), and the secrecy throughput of the proposed system are obtained, based on which we optimize the time-switching ratio to maximize the secrecy throughput. We also degenerate the proposed SWIPT-FDSJ scheme to the reduced half-duplex with no self-jamming (HDNSJ) scheme. The finds suggest that in the HDNSJ scheme, adding the antenna number of the source only benefits the COP performance, but has no impact on the SOP performance. By contrast, it will promote the COP and SOP performance at the same time in the SWIPT-FDSJ scheme, which eventually results in the great improvement of secrecy throughput. In addition, we present the practical application condition of the SWIPT-FDSJ scheme. It is demonstrated that the secrecy throughput performance of the SWIPT-FDSJ scheme is much superior to the HDNSJ scheme on condition that the application condition is satisfied.

Full-Duplex Destination-Aided Jamming Scheme for SWIPT-Enabled Relay Networks

Haowei Wu, Liubin Wang, Rui Ma +2 more

Simultaneous wireless information and power transfer (SWIPT) is a promising technique for energy-constrained wireless networks. To improve the security of SWIPT-enabled relay networks, in this paper, a full-duplex (FD) destination-aided jamming strategy is proposed, where a power splitting (PS) scheme is considered and two transmission phases are designed. In the first phase, the energy-limited half-duplex relay receives the signal superposed by confidential information and artificial noise (AN) from the source and destination, respectively. And then the FD destination transmits AN to the passive eavesdropper and receives the signal from the relay concurrently in the second phase. To maximize the secrecy capacity (SC), the individual optimizations of the PS ratio and power allocation (PA) coefficient are investigated, and the approximate optimal closed-form solutions of PS and PA ratios are derived. Besides, an iterative algorithm is also proposed to obtain the global optimal SC by updating the PS and PA ratios alternately. Simulation results confirm that the theoretical PS and PA ratios coincide closely with the exact results, and demonstrate that the optimal SC obtained by the iterative algorithm matches well with that given by the exhaustive search.
