Safety monitoring under stealthy sensor injection attacks using reachable sets
Cédric Escudero, Michelle S. Chong, Paolo Massioni +1
Stealthy sensor injection attacks are serious threats for industrial plants as they can compromise the plant's integrity without being detected by traditional fault detectors. In t…
Plug-and-Play Secondary Control for Safety of LTI Systems under Attacks
Yankai Lin, Michelle S. Chong, Carlos Murguia
We consider the problem of controller design for linear time-invariant cyber-physical systems (CPSs) controlled via networks. Specifically, we adopt the set-up that a controller ha…
Resilient Set-based State Estimation for Linear Time-Invariant Systems Using Zonotopes
Muhammad Umar B. Niazi, Amr Alanwar, Michelle S. Chong +1
This paper considers the problem of set-based state estimation for linear time-invariant (LTI) systems under time-varying sensor attacks. Provided that the LTI system is stable and…
Vulnerability of linear systems against sensor attacks--a system's security index
Michelle S. Chong, Margreta Kuijper
The `security index' of a discrete-time LTI system under sensor attacks is introduced as a quantitative measure on the security of an observable system. We derive ideas from error…
