Joint Resource Allocation in Secure OFDM Two-Way Untrusted Relay System [PDF]
Sensors, 2022 The security issue of wireless communication is a common concern because of its broadcast nature, especially when the relay becomes an eavesdropper. In the orthogonal frequency division multiplexing (OFDM) relay system, when the relay is untrusted, the ...

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 ...

Two-Hop Secure Communication Using an Untrusted Relay [PDF]
EURASIP Journal on Wireless Communications and Networking, 2009 We consider a source-destination pair that can only communicate through an untrusted intermediate relay node. The intermediate node is willing to employ a designated relaying scheme to facilitate reliable communication between the source and the ...

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 ...

Multi-terminal networks with an untrusted relay [PDF]
2014 52nd Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2014 This paper investigates the impact of cooperation with an untrusted relay in multi-source multi-destination networks. The set up considered is one where the relay is the only means of communications due to the absence of direct links between the sources and the destinations.

Secure Transmission for Simultaneous Wireless Information and Power Transfer in AF Untrusted Relay Networks [PDF]
Sensors, 2018 This paper investigates secure communications of energy harvesting untrusted relay networks, where the destination assists jamming signal to prevent the untrusted relay from eavesdropping and to improve the forwarding ability of the energy constrained ...

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 ...

Impact of Outdated CSI on the Secure Communication in Untrusted In-Band Full-Duplex Relay Networks
IEEE Access, 2022 To provide reliable connectivity in recent and future wireless communication systems, it is necessary to deploy several relay nodes. Further, a full-duplex (FD) technique has been in the spotlight since it can significantly improve spectral efficiency ...
