Secure transmission of cognitive untrusted relay networks with selection diversity
2017 9th International Conference on Wireless Communications and Signal Processing (WCSP), 2017In this paper, we investigate the secrecy performance of a cognitive untrusted relay network with a direct link using selection combining (SC) scheme, where a secondary source communicates with a secondary destination through an untrusted relay. We first examine the connection outage probability (COP) and secrecy outage probability (SOP) to investigate

Secure Transmit Beamforming in the RF Powered Untrusted Relay networks
2019 Computing, Communications and IoT Applications (ComComAp), 2019This paper investigates secure transmission in the radio-frequency (RF) powered untrusted relay networks. The relay conducts amplify-and-forward (AF) protocol and may intercept information passively. Based on the physical-layer security technique, a two-phase communication protocol is proposed for transmit security. We aim to minimize the average total

Physical Layer Security with Untrusted Relays in Wireless Cooperative Networks
2017 IEEE Wireless Communications and Networking Conference (WCNC), 2017We investigate the problem of physical layer security in a wireless cooperative network, where communication is assisted by the untrusted relay. It is impossible for the amplify-and-forward protocol to convey a confidential message from the source to the destination without the help of other nodes, where only an untrusted relay is available ...

Secure Relay Selection for UAV-empowered Two Way Untrusted Relaying Networks
2024 2nd International Conference On Mobile Internet, Cloud Computing and Information Security (MICCIS)In this paper, we examine the security aspects of two-way untrusted relaying networks (TWURNs) through the lens of physical layer security (PLS). These networks involve the exchange of confidential information between two multiple-antenna base stations ...
