A Moving Target Defense for Securing Cyber-Physical Systems
Paul Griffioen, Sean Weerakkody, Bruno Sinopoli
This article considers the design and analysis of multiple moving target defenses for recognizing and isolating attacks on cyber-physical systems. We consider attackers who perform…
A Bernoulli-Gaussian Physical Watermark for Detecting Integrity Attacks in Control Systems
Sean Weerakkody, Omur Ozel, Bruno Sinopoli
We examine the merit of Bernoulli packet drops in actively detecting integrity attacks on control systems. The aim is to detect an adversary who delivers fake sensor measurements t…
Detecting Integrity Attacks on Control Systems using a Moving Target Approach
Sean Weerakkody, Bruno Sinopoli
Maintaining the security of control systems in the presence of integrity attacks is a significant challenge. In literature, several possible attacks against control systems have be…
A Moving Target Approach for Identifying Malicious Sensors in Control Systems
Sean Weerakkody, Bruno Sinopoli
In this paper, we consider the problem of attack identification in cyber-physical systems (CPS). Attack identification is often critical for the recovery and performance of a CPS t…
Information Flow for Security in Control Systems
Sean Weerakkody, Bruno Sinopoli, Soummya Kar +1
This paper considers the development of information flow analyses to support resilient design and active detection of adversaries in cyber physical systems (CPS). The area of CPS s…
A Graph Theoretic Characterization of Perfect Attackability and Detection in Distributed Control Systems
Sean Weerakkody, Xiaofei Liu, Sang H. Son +1
This paper is concerned with the analysis and design of secure Distributed Control Systems in the face of integrity attacks on sensors and controllers by external attackers or insi…
Multi-Sensor Scheduling for State Estimation with Event-Based, Stochastic Triggers
Sean Weerakkody, Yilin Mo, Bruno Sinopoli +2
In networked systems, state estimation is hampered by communication limits. Past approaches, which consider scheduling sensors through deterministic event-triggers, reduce communic…
Stochastic Event-triggered Sensor Schedule for Remote State Estimation
Duo Han, Yilin Mo, Junfeng Wu +3
We propose an open-loop and a closed-loop stochastic event-triggered sensor schedule for remote state estimation. Both schedules overcome the essential difficulties of existing sch…
