On Frequency-Weighted Extended Balanced Truncation
Sribalaji C. Anand, Henrik Sandberg
This paper addresses the problem of frequency-weighted extended balanced truncation for discrete and continuous-time linear time-invariant plants. We show that the frequency-weight…
Quantifying Security for Networked Control Systems: A Review
Sribalaji C. Anand, Anh Tung Nguyen, André M. H. Teixeira +2
Networked Control Systems (NCSs) are integral in critical infrastructures such as power grids, transportation networks, and production systems. Ensuring the resilient operation of…
Security Metrics for Uncertain Interconnected Systems under Stealthy Data Injection Attacks
Anh Tung Nguyen, Sribalaji C. Anand, André M. H. Teixeira
This paper quantifies the security of uncertain interconnected systems under stealthy data injection attacks. In particular, we consider a large-scale system composed of a certain…
Security of Gradient Tracking Algorithms Against Malicious Agents
Sribalaji C. Anand, Alexander J Gallo, Nicola Bastianello
Consensus algorithms are fundamental to multi-agent distributed optimization, and their security under adversarial conditions is an active area of research. While prior works prima…
Feasibility of Randomized Detector Tuning for Attack Impact Mitigation
Sribalaji C. Anand, Kamil Hassan, Henrik Sandberg
This paper considers the problem of detector tuning against false data injection attacks. In particular, we consider an adversary injecting false sensor data to maximize the state…
Switching multiplicative watermark design against covert attacks
Alexander J. Gallo, Sribalaji C. Anand, André M. H. Teixeira +1
Active techniques have been introduced to give better detectability performance for cyber-attack diagnosis in cyber-physical systems (CPS). In this paper, switching multiplicative…
