Qinhong Jiang (蒋沁宏)

A postdoctoral researcher in cyber-physical system (CPS) security and privacy.

I am currently a postdoctoral researcher at IMCL lab in The Hong Kong Polytechnic University, advised by Prof. Jiannong Cao. Prior that, I received my PhD degree from the Zhejing University, where I’m honored to be advised by Prof. Wenyuan Xu, Prof. Xiaoyu Ji and Prof. Chen Yan at the Ubiquitous System Security Laboratory (USSLAB).

My research aims to protect the security and privacy of cyber-physical systems and spans the intersections of embedded systems, sensing, and mobile computing. Most of my research focuses on the security and privacy threats of cyber-physical systems caused by vulnerabilities against electromagnetic waves. I am also interested in side-channel attacks, robot system security, machine learning security, large language model security, and anything in security and privacy research that involves signals and physics.

I am open to academic collaborations and welcome discussions concerning potential research partnerships.

  • [Nov 22, 2024] Our paper GhostShot has been accepted at NDSS’25. We conducted a schematic analysis of the causality of the IEMI effect on the shapes, brightness, and colors of the injected images, and achieve fine-grained control of the injected pattern. (PDF, Demo)
  • [Aug 31, 2024] Our paper PhantomLiDAR has been accepted at NDSS’25. We demonstrate how cross-modality signal injection attacks, i.e., IEMI, can manipulate LiDAR output. (PDF, Demo)
  • [Aug 5, 2024] I am joining the IMCL lab in The Hong Kong Polytechnic University as a postdoctoral fellow, directed by Prof. Jiannong Cao.
  • [June 1, 2024] Successfully defended my Ph.D. thesis!
  • [Mar 13, 2024] One paper has been accepted at IEEE Conference on Multimedia Expo 2024 (ICME’24).
  • [Nov 26, 2023] One paper has been accepted at IEEE Transactions on Information Forensics and Security (IEEE TIFS). (PDF, Demo)
  • [Sep 15, 2023] My co-first authored paper EM Eye has been accepted at NDSS’24 without revisions. We demonstrate how attackers may eavesdrop on cameras and recover high-quality images in real time by analyzing camera’s side-channel EM leakage. (PDF, Demo, Repo)
  • [Jun 22, 2023] My paper GhostType paper has been accepted at NDSS’24. We uncover a new class of vulnerabilities that can be exploited to induce phantom keystrokes (especially the keys that do not exist on the physical keyboard) into keyboards’ analog circuits in a contactless way using intentional electromagnetic interference. (PDF, Demo)
  • [Jul 15, 2022] My paper GlitchHiker has been accepted at USENIX’23. We uncover the vulnerabilities of image signal transmission and demonstrate how attackers may actively induce controlled glitch images of a camera at various positions, widths, and numbers using intentional electromagnetic interference.
