Covert Beamforming Design for Intelligent Reflecting Surface Assisted IoT Networks
Shuai Ma, Yunqi Zhang, Hang Li +5
In this paper, we consider covert beamforming design for intelligent reflecting surface (IRS) assisted Internet of Things (IoT) networks, where Alice utilizes IRS to covertly trans…
Robust Beamforming Design for Covert Communications
Shuai Ma, Yunqi Zhang, Hang Li +4
In this paper, we consider a common unicast beamforming network where Alice utilizes the communication to Carol as a cover and covertly transmits a message to Bob without being rec…
WLAN-Log-Based Superspreader Detection in the COVID-19 Pandemic
Cheng Zhang, Yunze Pan, Yunqi Zhang +5
Identifying "superspreaders" of disease is a pressing concern for society during pandemics such as COVID-19. Superspreaders represent a group of people who have much more social co…
ACOUSTIC-TURF: Acoustic-based Privacy-Preserving COVID-19 Contact Tracing
Yuxiang Luo, Cheng Zhang, Yunqi Zhang +5
In this paper, we propose a new privacy-preserving, automated contact tracing system, ACOUSTIC-TURF, to fight COVID-19 using acoustic signals sent from ubiquitous mobile devices. A…
