“…Some of them, such as [3], [5], [8]- [11], [16]- [19], [22]- [23], [27]- [29], [34]- [35], studied the secrecy transmission in SWIPT while considering perfect/imperfect CSI. Making use of artificial noise method, the authors of [44] designed a joint information and energy transmit beamforming scheme to maximize the secrecy rate of the IR in a secret MISO SWIPT system.…”

In wireless powered networks, a user can make a request and use the wireless energy transferred from an energy source for its data transmission. However, due to broadcast nature of wireless energy transfer (e.g., RF energy), a malicious node (i.e., an attacker) can also intercept the energy and use it to perform an attack by jamming the data transmission of the user. We consider such a jamming attack where the user and attacker are aware of each other. We formulate a game theoretic model to analyze the energy request and data transmission policy of the user and the attack policy of the attacker when the user and the attacker both want to maximize their own rewards. We use an iterative algorithm designed based on the best response dynamics to obtain the solution defined in terms of the constrained Nash equilibrium. The numerical results show not only the convergence of the proposed algorithm, but also the optimal reward of the user under different energy cost constraints.

“…The authors in [21] studied secure relay beamforming for SWIPT in one-way relay systems with an external energy-harvested receiver. In [22], the authors considered a wireless-powered jammer system, where the jammer can harvest energy from the wireless signal and use it to interfere with the eavesdropper.…”

Abstract-In this work, we maximize the secrecy rate of the wireless-powered untrusted relay network by jointly designing power splitting (PS) ratio and relay beamforming with the proposed global optimal algorithm (GOA) and local optimal algorithm (LOA). Different from the literature, artificial noise (AN) sent by the destination not only degrades the channel condition of the eavesdropper to improve the secrecy rate, but also becomes a new source of energy powering the untrusted relay based on PS. Hence, it is of high economic benefits and efficiency to take advantage of AN compared with the literature. Simulation results show that LOA can achieve satisfactory secrecy rate performance compared with that of GOA, but with less computation time.
