Distributed Matching Algorithms: Maximizing Secrecy in the Presence of Untrusted Relay [PDF]
Radioengineering, 2017 In this paper, we propose a secrecy sum-rate maximization based matching algorithm between primary transmitters and secondary cooperative jammers in the presence of an eavesdropper.

Physical Layer Security in an Untrusted Energy Harvesting Relay Network
IEEE Access, 2019 The security performance in an amplify-and-forward dual-hop untrusted relay network is considered. It is assumed that the source and multiple destinations are equipped with multiple antennas, and the information transmission is aided by a single-antenna ...

Secure communication via untrusted switchable decode-and-forward relay
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 ...

Secrecy Rate-Optimum Energy Splitting for an Untrusted and Energy Harvesting Relay Network
IEEE Access, 2018 In this paper, a destination-assisted-jamming-based secure transmission is devised for an untrusted and energy harvesting relay network. In the proposed scheme, both source and destination split their energies into two parts for energy harvesting at the ...

Joint power control for untrusted relay cooperation-based confidential communication
Tongxin xuebao, 2014 The scenario that multiple cell-edge mobile stations (MS) all without direct-links to the base station (BS) but have confidential messages in the uplink in the presence of untrusted relay (UR) cooperation was considered.In order to implement the secure ...
