Secure Transmit Beamforming in the RF Powered Untrusted Relay networks

2019 Computing, Communications and IoT Applications (ComComAp), 2019
This 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), 2017
We 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 ...
