Secure Multiuser Communications in Wireless Sensor Networks with TAS and Cooperative Jamming
Sensors, 2016 In this paper, we investigate the secure transmission in wireless sensor networks (WSNs) consisting of one multiple-antenna base station (BS), multiple single-antenna legitimate users, one single-antenna eavesdropper and one multiple-antenna cooperative ...

Enhancing Physical Layer Security of DF Buffer-Aided Relay Networks With Small Buffer Sizes
IEEE Access, 2019 In this paper, we propose a novel max-weight secure link selection (MWSLS) scheme to enhance physical layer security of decode-and-forward (DF) buffer-aided relay networks. The MWSLS scheme can select the link with the largest weight among all secure and

Security–reliability tradeoff analysis of untrusted energy harvesting relay networks
International Journal of Distributed Sensor Networks, 2018 We investigate secure communications in untrusted energy harvesting relay networks, where the amplify-and-forward relay is an energy constrained node powered by the received radio frequency signals, and try to unauthorizedly decode the confidential ...

Secure Transmission for Differential Quadrature Spatial Modulation With Artificial Noise
IEEE Access, 2019 In this paper, we investigate the secure transmission for differential quadrature spatial modulation (DQSM) with artificial noise (AN) in multiple-input single-output wiretap networks, where a cooperative jammer helps the secure transmission between ...

ZF-SIC Based Individual Secrecy in SIMO Multiple Access Wiretap Channel
IEEE Access, 2017 In this paper, a decoding method of joint zero-forcing and successive interference cancellation (ZF-SIC) is put forward to assist the study of the individual secrecy in the quasi-static Rayleigh fading single-input multiple-output multiple access wiretap

Cooperative Secure Transmission in the Presence of Untrusted Relay
International Journal of Distributed Sensor Networks, 2016 Considering a nonregenerative untrusted relay network, we investigate three different secure transmission strategies, for example, noncooperative strategy, conventional amplify-and-forward (AF) strategy, and cooperative jamming (CJ) strategy.
