Stealthy bias injection attack detection based on Kullback-Leibler divergence in noisy linear systems
Jingwei Dong, André M. H. Teixeira
This paper studies the design of observer gains to enhance the detectability of stealthy bias injection attacks (BIAs) in linear systems driven by Gaussian noise, where adversaries…

Fundamental limitations of sensitivity metrics for anomaly impact analysis in LTI systems
Jingwei Dong, Kangkang Zhang, Anh Tung Nguyen +1
This study establishes a connection between the output-to-output gain (OOG), a sensitivity metric quantifying the impact of stealthy attacks, and a novel input-to-input gain (IIG)…

Distributed Multiple Fault Detection and Estimation in DC Microgrids with Unknown Power Loads
Jingwei Dong, Mahdieh S. Sadabadi, Per Mattsson +1
This paper proposes a distributed diagnosis scheme to detect and estimate actuator and power line faults in DC microgrids (e.g., electric-vehicle charging microgrids) subject to un…
