I am a final-year Ph.D. student at Zhejiang University (ZJU). I obtained my B.E. degree in 2020 from Nanjing University of Posts and Telecommunications.
My doctoral research is under the guidance of Prof. Wenyuan Xu and Prof. Xiaoyu Ji at ZJU. Recently, my research interests involve around IoT security, with a particular focus on the sensor & algorithm security, malicious power and hardware security. I have contributed to several publications in leading security conferences and journals such as IEEE S&P, NDSS, ICASSP, and TDSC.

📝 Publications d

PowerRadio: Manipulate Sensor Measurement via Power GND Radiation
Yan Jiang, Xiaoyu Ji, Yancheng Jiang, Kai Wang, Chenren Xu, Wenyuan Xu
- In this paper, we open up a new threat vector to sensor measurements. Specifically, we explore the energy conversion of wired signals, and design a power cable-based sensor manipulation attack, named “PowerRadio”. PowerRadio can tamper with sensors’ readings across sockets and household wiring system.

WIGHT: Wired Ghost Touch Attack on Capacitive Touchscreens
Yan Jiang, Xiaoyu Ji, Kai Wang, Chen Yan, Richard Mitev, Ahmad-Reza Sadeghi, Wenyuan Xu
- In this paper, we reveal for the first time that the capacitive touchscreens on mobile devices like smartphone, tablet and GPS can be remotely manipulated via power cables. We presenst a practical attack named “WIGHT”, which can inject fake touches, alter users’ touch operations and disable the touchscreen. We verified the feasibility of WIGHT on touchscreen panels and commercial devices of brands like Apple, Huawei and Xiaomi.
