“…Third, the CSI corresponding to the information receiver may be imperfect, as it is required to be conveyed from the receiver to the transmitter. In this context, it is necessary to design robust secure beamforming for SWIPT with partial and imperfect CSI [6], [7], [10].…”

“…However, the CSI may be imperfect due to channel estimation errors or limited CSI feedback. Thus, the authors in [6] designed a robust beamforming scheme for multiple-antenna SWIPT systems in the presence of channel uncertainty of information and power receivers. To further improve the performance of SWIPT, the authors in [7] proposed to use both artificial noise (AN) and power signal to confuse eavesdroppers and increase the amount of harvested energy simultaneously through proper spatial beamforming.…”

Wireless information and power transfer (WIPT) enables more sustainable and resilient communications owing to the fact that it avoids frequent battery charging and replacement. However, it also suffers from possible information interception due to the open nature of wireless channels. Compared to traditional secure communications, secrecy wireless information and power transfer (SWIPT) carries several distinct characteristics. On one hand, wireless power transfer may increase the vulnerability of eavesdropping, since a power receiver, as a potential eavesdropper, usually has a shorter access distance than an information receiver. On the other hand, wireless power transfer can be exploited to enhance wireless security. This article reviews the security issues in various SWIPT scenarios, with an emphasis on revealing the corresponding challenges and opportunities for implementing SWIPT. Furthermore, we provide a survey on a variety of physical layer security techniques to improve secrecy performance.In particular, we propose to use massive multiple-input multiple-output (MIMO) techniques to enhance power transfer efficiency and secure information transmission simultaneously. Finally, we discuss several potential research directions to further enhance the security in SWIPT systems.

“…Following these pioneering works, plenty of works have been done for various wireless networks, including cooperative relaying network [12][13][14][15][16], power allocation strategies [17][18][19], resource scheduling [20,21], and multiple-input multiple-out (MIMO) system [22][23][24] or multiple-input single-output (MISO) [25,26]. In [12], the authors analyzed the system maximal throughput for the time switching and power splitting protocols in AF relaying networks.…”

This paper investigates the outage probability of an energy harvesting (EH) relay-aided cooperative network, where a source node transmits information to its destination node with the help of an energy harvesting cooperative node. For such a system, we derive an explicit closed-form expression of outage probability over Nakagami-m fading channels for both amplify-and-forward (AF) and decode-and-forward (DF) relay protocols, and we verify the explicit closed-form expressions of outage probability with the Monte Carlo method. It is shown that the simulation results match well with the numerical ones. From the numerical analysis and simulation results, it can be observed that the system parameters have great impact on both AF and DF relay systems. For the DF system, with the increment of the power splitting ratio, the system outage probability decreases, while for the AF system, with the increment of the power splitting ratio, it first increases and then decreases. Besides, for both DF and AF systems, when the relay is placed relatively closer to the source, better outage performance will be achieved.

“…In a MIMO SWIPT system, the authors of [33] analyzed and derived closed-form representations of the ergodic downlink rate, and both the energy shortage and data outage probability were derived for the three cases of CSI at the transmitter: no CSI, and imperfect CSI in case of time-division duplexing and frequency-division duplexing communications. In a MIMO SWIPT system, the authors of [27] investigated the robust secure transmission scheme to maximize the worst-case secrecy rate under transmitting power constraint and EH constraint while considering channel uncertainties. A robust artificial noise-aided secure transmission design was studied in [28] for MIMO SWIPT systems, where the channel uncertainties are modeled by worst-case model.…”
