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 ...

On the Achievable Secrecy Diversity of Cooperative Networks With Untrusted Relays [PDF]
IEEE Transactions on Communications, 2018 Cooperative relaying is often deployed to enhance the communication reliability (i.e., diversity order) and consequently the end-to-end achievable rate. However, this raises several security concerns when the relays are untrusted since they may have access to the relayed message.

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 ...

General Secure Information Exchange Protocol for a Multiuser MIMO Relay Channel
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

On the Secrecy Performance and Power Allocation in Relaying Networks With Untrusted Relay in the Partial Secrecy Regime [PDF]
IEEE Transactions on Information Forensics and Security, 2020 Recently, three useful secrecy metrics based on the partial secrecy regime were proposed to analyze secure transmissions on wireless systems over quasi-static fading channels, namely: generalized secrecy outage probability, average fractional equivocation, and average information leakage.
