Secrecy outage probability analysis for RIS‐assisted NOMA systems [PDF]
Electronics Letters, 2020 In this Letter, the physical layer security for a novel reconfigurable intelligent surface (RIS)‐assisted non‐orthogonal multiple access (NOMA) system in a multi‐user scenario is investigated, where the authors consider the worst case that the eavesdropper also utilises the advantage of the RISs.

On secrecy outage probability for downlink NOMA systems with relay–antenna selection [PDF]
EURASIP Journal on Advances in Signal Processing, 2021 AbstractSecure transmission is essential for future non-orthogonal multiple access (NOMA) system. This paper investigates relay–antenna selection to enhance physical-layer security of cooperative NOMA system in the presence of an eavesdropper, where multiple antennas are deployed at the relays, the users, and the eavesdropper.
