Relay Selection for Secure Successive AF Relaying Networks With Untrusted Nodes

IEEE Transactions on Information Forensics and Security, 2016
In this paper, the security aspect of an amplify-and-forward relaying network with untrusted relay nodes is considered. The untrusted nodes can help to forward the received signal and they may also try to decode such information, which can be regarded as potential eavesdroppers (Eves). To deal with such a challenging issue, a successive relaying scheme

Opportunistic Transmission of Nonregenerative Network With Untrusted Relay

IEEE Transactions on Vehicular Technology, 2015
In this paper, we consider an opportunistic transmission scheme of nonregenerative relay networks consisting of a source, a destination, and an untrusted relay, where the relay has a different security clearance from the source–destination pair. In this network, the information is transmitted through the direct link if the secrecy rate of the direct ...

Secure Cooperative Communications With an Untrusted Relay: A NOMA-Inspired Jamming and Relaying Approach

IEEE Transactions on Information Forensics and Security, 2019
We propose a novel non-orthogonal multiple access (NOMA)-inspired jamming and relaying scheme to enhance the physical layer security of untrusted relay networks. Particularly, during the first phase, with the application of the downlink NOMA principle, the source sends a superimposed version of a desired signal and a jamming signal, where the jamming ...

Secure Relay Selection for Two Way Amplify-and-Forward Untrusted Relaying Networks

IEEE Transactions on Vehicular Technology, 2018
Relay assisted communication helps to extend the transmission coverage area. In more realistic scenarios, the available relays are untrusted, which try to decode the confidential signals during their main relaying function. Thus, these untrusted relays are regarded as potential eavesdroppers, and the confidential signals are vulnerable.
