Physical Layer Security in Two-Way SWIPT Relay Networks with Imperfect CSI and a Friendly Jammer
Entropy, 2023 In this paper, the security of two-way relay communications in the presence of a passive eavesdropper is investigated. Two users communicate via a relay that depends solely on energy harvesting to amplify and forward the received signals.
