Covert Communication in Intelligent Reflecting Surface-Assisted NOMA Systems: Design, Analysis, and Optimization
Lu Lv, Qingqing Wu, Zan Li +3
In this paper, we investigate covert communication in an intelligent reflecting surface (IRS)-assisted non-orthogonal multiple access (NOMA) system, where a legitimate transmitter…
Physical Layer Security Enhancement Using Artificial Noise in Cellular Vehicle-to-Everything (C-V2X) Networks
Chao Wang, Zan Li, Gen Xiang Xia +3
The secure transmission of confidential information in cellular vehicle-to-everything (C-V2X) communication networks is vitally important for user's personal safety. However, for C…
Secure Two-Way Communications via Intelligent Reflecting Surfaces
Lu Lv, Qingqing Wu, Zan Li +2
In this letter, we propose to exploit an intelligent reflecting surface (IRS) to secure multiuser two-way communications. Specifically, two end users simultaneously transmit their…
Covert Transmission Assisted by Intelligent Reflecting Surface
Jiangbo Si, Zan Li, Yan Zhao +4
Covert transmission is studied for an intelligent reflecting surface (IRS) aided communication system, where Alice aims to transmit messages to Bob without being detected by the wa…
Cooperative Jamming for Secure Transmission With Both Active and Passive Eavesdroppers
Jiangbo Si, Zihao Cheng, Zan Li +3
Secrecy transmission is investigated for a cooperative jamming scheme, where a multi-antenna jam-mer generates artificial noise (AN) to confuse eavesdroppers. Two kinds of eavesdro…
Covert Surveillance via Proactive Eavesdropping Under Channel Uncertainty
Zihao Cheng, Jiangbo Si, Zan Li +2
Surveillance performance is studied for a wireless eavesdropping system, where a full-duplex legitimate monitor eavesdrops a suspicious link efficiently with the artificial noise (…
