Yu Jin  (金宇)

I am a Ph.D. student in the Department of Electronic Engineering, Tsinghua University , supervised by Prof. Shuwen Deng , majoring in Electronic Science and Technology.

My research interests focus on Microarchitecture Security Analysis and Secure Optimization Mechanism Design. I have discovered multiple novel attack vectors across x86-64/ARM/RISC-V architectures, including cache coherence-based attacks (GhostCache, CCS'25), transient execution timing attacks (Whisper, DAC'24), page table walk side-channels (Stone-Skimming, DAC'26), prefetcher-based side-channels (PPA, AsianHOST'25 Best Paper), and so on. My research objective is to build a secure and efficient microarchitecture and to protect the security of the computing system from the hardware level.

Brief of previous experience in research and industry before Ph.D.

I finished my graduate study and got a M.Phil. degree at BUPT in the summer of 2025, supervised by Prof. Chunlu Wang and Prof. Pengfei Qiu.

I was engaged in machine learning years ago, such as interning in Megvii Research and building some projects (infrastructure for ML/CV), these experiences help me a lot in my current research for side-channel information analysis and the get motivation of research.

In my last year of undergraduate, I was a research intern at Megvii Research, advised by Dr. Su Wang and managed by Mr. Xinyu Zhou. Before that, I finished my graduation internship at Alibaba Group. And I completed my B.S. in Computer Science at Wuhan University of Technology.
