IoT/CPS Security Research at the University of Michigan

Welcome! This website documents research in Internet of Things and Cyber-Physical Systems Security. The research is primarily conducted by the University of Michigan and its collaborators at Microsoft Research, University of Illinois, University of Washington, University of California Berkeley, and Stony Brook University. We provide a few resources in the form of research papers, code, demo videos and frequently asked questions (FAQs).
