Resilient Scheduling of Control Software Updates in Radial Power Distribution Systems
Kin Cheong Sou, Henrik Sandberg
In response to newly found security vulnerabilities, or as part of a moving target defense, a fast and safe control software update scheme for networked control systems is highly d…
Complexity reduction for resilient state estimation of uniformly observable nonlinear systems
Junsoo Kim, Jin Gyu Lee, Henrik Sandberg +1
A resilient state estimation scheme for uniformly observable nonlinear systems, based on a method for local identification of sensor attacks, is presented. The estimation problem i…
Strategic Monitoring of Networked Systems with Heterogeneous Security Levels
Jezdimir Milosevic, Mathieu Dahan, Saurabh Amin +1
We consider a strategic network monitoring problem involving the operator of a networked system and an attacker. The operator aims to randomize the placement of multiple protected…
The Fundamental Limitations of Learning Linear-Quadratic Regulators
Bruce D. Lee, Ingvar Ziemann, Anastasios Tsiamis +2
We present a local minimax lower bound on the excess cost of designing a linear-quadratic controller from offline data. The bound is valid for any offline exploration policy that c…
Attack Impact Evaluation for Stochastic Control Systems through Alarm Flag State Augmentation
Hampei Sasahara, Takashi Tanaka, Henrik Sandberg
This note addresses the problem of evaluating the impact of an attack on discrete-time nonlinear stochastic control systems. The problem is formulated as an optimal control problem…
Comparison of encrypted control approaches and tutorial on dynamic systems using LWE-based homomorphic encryption
Junsoo Kim, Dongwoo Kim, Yongsoo Song +3
Encrypted control has been introduced to protect controller data by encryption at the stage of computation and communication, by performing the computation directly on encrypted da…
