OFDMA-Based DF Secure Cooperative Communication With Untrusted Users

open access: yes, 2016
In this letter, we consider resource allocation for OFDMA-based secure cooperative communication by employing a trusted decode and forward (DF) relay among the untrusted users.

Physical Layer Security for Two-Way Untrusted Relaying With Friendly Jammers

open access: yes, 2012
In this paper, we consider a two-way relay system where the two sources can only communicate through an untrusted intermediate relay and investigate the physical layer security issue in this two-way untrusted relay scenario.

User-Pair Selection in Multiuser Cooperative Networks With an Untrusted Relay [PDF]

open access: yes, 2019
This paper investigates the physical-layer security of an amplify-and-forward wireless cooperative network, where N source nodes communicate with their corresponding destination nodes under the help of an untrusted relay. In each slot, only one user-pair

Secure Two-Way Transmission via Wireless-Powered Untrusted Relay and External Jammer [PDF]

open access: yes, 2018
In this paper, we propose a two-way secure communication scheme where two transceivers exchange confidential messages via a wireless-powered untrusted amplify-and-forward (AF) relay in the presence of an external jammer.

Secure transmission in backhaul NOMA systems: A physical layer security design with untrusted user and eavesdropper

open access: yesDigital Communications and Networks
In order to improve the Physical Layer Security (PLS) perspective, this paper aims to empower function of PLS by considering a backhaul Non-Orthogonal Multiple Access (NOMA) system in two practical situations.
