Securing Untrusted RF-EH Relay Networks Using Cooperative Jamming Signals [PDF]
IEEE Access, 2017 We propose a new scheme to secure a wireless-powered untrusted cooperative-communication network, where a legitimate source node (Alice) transmits her information messages to a legitimate destination node (Bob) through the multiple amplify-and-forward ...

General Secure Information Exchange Protocol for a Multiuser MIMO Relay Channel [PDF]
Entropy, 2019 Secure information exchange occurs in many recently emerging cooperative-based networks, such as 5G networks (especially those with a Device to Device architecture), the Internet of Things, and vehicular ad hoc networks. However, the existing information

Security–reliability tradeoff analysis of untrusted energy harvesting relay networks
International Journal of Distributed Sensor Networks, 2018 We investigate secure communications in untrusted energy harvesting relay networks, where the amplify-and-forward relay is an energy constrained node powered by the received radio frequency signals, and try to unauthorizedly decode the confidential ...

Joint Antenna and User Selection for Untrusted Relay Networks [PDF]
2018 IEEE Global Communications Conference (GLOBECOM), 2018 In this paper, we investigate secure communication for an untrusted relay network, in which a source equipped with $N_{S}$ antennas communicates to $M$ users with the help of an untrusted relay. To protect the data confidentially while concurrently relying on the untrusted relays, joint antenna and user selection scheme has been proposed with the ...

Physical layer security: Friendly jamming in an untrusted relay scenario [PDF]
2016 24th European Signal Processing Conference (EUSIPCO), 2016 This paper investigates the achievable secrecy regions when employing a friendly jammer in a cooperative scenario employing an untrusted relay. The untrusted relay which helps to forward the source signal towards the destination, could also be regarded as a potential eavesdropper.

Covertness and Secrecy Study in Untrusted Relay-Assisted D2D Networks [PDF]
IEEE Internet of Things Journal, 2023 Abstract This article investigates the covertness and secrecy of wireless communications in an untrusted relay-assisted device-to-device (D2D) network consisting of a full-duplex base station (BS), a user equipment (UE), and an untrusted relay \(R\). For the covertness, we attempt to prevent Willie from detecting the very existence of communications ...

Secure communication via untrusted switchable decode-and-forward relay [PDF]
2017 13th International Wireless Communications and Mobile Computing Conference (IWCMC), 2017 In this paper, a practical power efficient technique is proposed for an untrusted decode-and-forward (DAF) based cooperative communication system to provide secure communication between the source and the destination. More specifically, a DAF relay, called switchable DAF (sDAF), is designed in such a way that it can be switched to amplify-and-forward ...
