Towards Secure and Energy-Efficient CRNs Via Embracing Interference: A Stochastic Geometry Approach
IEEE Access, 2018 In a cognitive radio network (CRN), the interference caused by secondary users (SUs) is conventionally regarded as an obstacle to the throughput of the primary network. However, when considering security, the interference brings potential benefits to the

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.

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

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 ...

On the Achievable Secrecy Throughput of Block Fading Channels with No Channel State Information at Transmitter [PDF]
2007 41st Annual Conference on Information Sciences and Systems, 2007 We study the block fading wire-tap channel, where a transmitter sends confidential messages to a legitimate receiver over a block fading channel in the presence of an eavesdropper, which listens to the transmission through another independent block fading channel.

Exploiting Uplink NOMA to Improve Sum Secrecy Throughput in IoT Networks
Wireless Communications and Mobile Computing, 2018 This paper exploits nonorthogonal multiple access (NOMA) to enhance the uplink secure transmission in Internet of Things (IoT) networks. Considering the different intercept ability of eavesdroppers (Eve), secrecy performances of both strong and weak Eve wiretap scenarios have been investigated. In strong Eve wiretap scenario (SWS), Eve is assumed to be
