Dynamic Median Consensus Over Random Networks
Shuhua Yu, Yuan Chen, Soummya Kar
This paper studies the problem of finding the median of N distinct numbers distributed across networked agents. Each agent updates its estimate for the median from noisy local obse…
Resilient Distributed Recovery of Large Fields
Yuan Chen, Soummya Kar, José M. F. Moura
This paper studies the resilient distributed recovery of large fields under measurement attacks, by a team of agents, where each measures a small subset of the components of a larg…
Resilient Distributed Field Estimation
Yuan Chen, Soummya Kar, José M. F. Moura
We study resilient distributed field estimation under measurement attacks. A network of agents or devices measures a large, spatially distributed physical field parameter. An adver…
Resilient Distributed Parameter Estimation with Heterogeneous Data
Yuan Chen, Soummya Kar, José M. F. Moura
This paper studies resilient distributed estimation under measurement attacks. A set of agents each makes successive local, linear, noisy measurements of an unknown vector field co…
The Internet of Things: Secure Distributed Inference
Yuan Chen, Soummya Kar, José M. F. Moura
The growth in the number of devices connected to the Internet of Things (IoT) poses major challenges in security. The integrity and trustworthiness of data and data analytics are i…
Resilient Distributed Estimation: Sensor Attacks
Yuan Chen, Soummya Kar, José M. F. Moura
This paper studies multi-agent distributed estimation under sensor attacks. Individual agents make sensor measurements of an unknown parameter belonging to a compact set, and, at e…
Resilient Distributed Estimation Through Adversary Detection
Yuan Chen, Soummya Kar, José M. F. Moura
This paper studies resilient multi-agent distributed estimation of an unknown vector parameter when a subset of the agents is adversarial. We present and analyze a Flag Raising Dis…
Optimal Attack Strategies Subject to Detection Constraints Against Cyber-Physical Systems
Yuan Chen, Soummya Kar, José M. F. Moura
This paper studies an attacker against a cyber-physical system (CPS) whose goal is to move the state of a CPS to a target state while ensuring that his or her probability of being…
Cyber Physical Attacks with Control Objectives
Yuan Chen, Soummya Kar, José M. F. Moura
This paper studies attackers with control objectives against cyber-physical systems (CPS). The system is equipped with its own controller and attack detector, and the goal of the a…
Dynamic Attack Detection in Cyber-Physical Systems with Side Initial State Information
Yuan Chen, Soummya Kar, Jose' M. F. Moura
This paper studies the impact of side initial state information on the detectability of data deception attacks against cyber-physical systems. We assume the attack detector has acc…
