Improving Secrecy Performance of a Wirelessly Powered Network [PDF]
IEEE Transactions on Communications, 2017 This paper considers the secrecy communication of a wirelessly powered network, where an energy-constrained legitimate transmitter (Alice) sends message to a legitimate receiver (Bob) with the energy harvested from a dedicated power beacon, while an eavesdropper (Eve) intends to intercept the information.

Secrecy performance analysis of IRS-NOMA systems
EURASIP Journal on Wireless Communications and Networking, 2023 AbstractIn this paper, we propose to utilize an intelligent reflecting surface (IRS) as a promising technology to enhance the coverage and physical layer security of non-orthogonal multiple access (NOMA) system. In particular, an IRS-assisted NOMA system is considered with the aid of careful channel ordering of the NOMA users, in which the transmitter ...

Secrecy Performance of Wirelessly Powered Wiretap Channels [PDF]
IEEE Transactions on Communications, 2016 This paper considers a wirelessly powered wiretap channel, where an energy constrained multi-antenna information source, powered by a dedicated power beacon, communicates with a legitimate user in the presence of a passive eavesdropper. Based on a simple time-switching protocol, where power transfer and information transmission are separated in time ...

On the Use of HAPS to Increase Secrecy Performance in Satellite Networks [PDF]
2021 IEEE International Conference on Communications Workshops (ICC Workshops), 2021 In this paper, we investigate the secrecy performance of radio frequency (RF) eavesdropping for a high altitude platform station (HAPS) aided satellite communication (SatCom) system. More precisely, we propose a new SatCom scheme where a HAPS node is used as an intermediate relay to transmit the satellite's signal to the ground station (GS).
