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

Performance Study of Untrusted Relay Network Utilizing Cooperative Jammer [PDF]
AUT Journal of Electrical Engineering, 2016 —In this paper, the problem of secure transmission in two-hop amplify-and-forward (AF) systems with an untrusted relay is investigated. To prevent the untrusted relay from intercepting the source message and to achieve positive secrecy rate, the ...

Cooperative Jamming-Based Physical-Layer Group Secret and Private Key Generation [PDF]
EntropyThis paper explores physical layer group key generation in wireless relay networks with a star topology. In this setup, the relay node plays the role of either a trusted or untrusted central node, while one legitimate node (Alice) acts as the reference ...

Cooperative Secure Transmission in the Presence of Untrusted Relay [PDF]
International Journal of Distributed Sensor Networks, 2016 Considering a nonregenerative untrusted relay network, we investigate three different secure transmission strategies, for example, noncooperative strategy, conventional amplify-and-forward (AF) strategy, and cooperative jamming (CJ) strategy.

Impact of Outdated CSI on the Secure Communication in Untrusted In-Band Full-Duplex Relay Networks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 ...
