State Estimation in Cyber-Physical Systems: Privacy and Safety Guarantees

The tight coupling of information technology with physical sensing and actuation has opened the door for privacy leakage and security vulnerability in the state estimation algorithms of Cyber-Physical Systems (CPS). Thus, we need a paradigm shift in the algorithmic design to estimate states of CPS privately, securely, and efficiently. We start by tackling privacy and security concerns while satisfying real-time requirements in estimating a moving target location. We present a localization system that combines partially homomorphic encryption with a new way of structuring the localization problem to enable efficient and accurate computation of a target's location without sacrificing the observers' privacy. Then, we move forward to safety-critical applications where the agents require safety guarantees on the reachability analysis results.
Bio: Amr Alanwar is a postdoctoral researcher at KTH Royal Institute of Technology working with Prof Karl Henrik Johansson. He graduated from the Cyber-Physical Systems Group under the supervision of Prof. Dr.-Ing. Matthias Althoff at Technical University of Munich (TUM). Before that, he was a research assistant at the University of California, Los Angeles (UCLA). He also has industrial experience as a research and development engineer in Mentor Graphics and Morpho companies. Amr won the Best Demonstration Paper Award at the 16th ACM/IEEE International Conference on Information Processing in Sensor Networks and was a finalist in the Qualcomm Innovation Fellowship for two years in a row. He received his B.Sc. and M.Sc from Ain Shams University, Cairo, Egypt. His current research interests include privacy, safety, estimation, and general topics in Cyber-Physical Systems (CPS).
