“…e FD destination node with the ability of emitting artificial noise is exploited to achieve better secrecy transmission in the threenode eavesdropping scenario of SWIPT, where the destination employed time-switching (TS) protocol to harvest energy, and the closed-form expressions of the connection outage probability (COP), the secrecy outage probability (SOP), the transmission outage probability (TOP), and the secrecy energy efficiency are derived [21]. In our previous study [22], an FD destination-assisted jamming scheme was adopted in a SWIPT-enabled trusted relay network, and the optimization problem was designed to achieve the optimal secrecy capacity, where only the PS scheme with the linear EH (LEH) model was considered.…”

“…Unlike these papers, the destination sent the jamming signal with FD to protect the classified information in our network, which is the fundamental difference between our and their works. Secondly, only the LEH model was utilized in [19,21,22], while both the linear and nonlinear EH models are considered in this treatise. irdly, the destination node was self-interference in our network, instead of disturbing the relay, which is unlike the network in [19].…”

“…In contrast to [20,21], the author investigated the three-node system, while the network in this paper consists of four nodes. Fourthly, both the PS-and TS-based schemes are employed, while only the PS scheme was applied in [19,22] and the TS in [22]. In addition, the COP, SOP, TOP, and ESC are analyzed in our research to provide a comprehensive and thorough guidance for practical application, while only SC was focused in [19,22].…”

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.
