A Fully Homomorphic Encryption Scheme for Real-Time Safe Control
Pieter Stobbe, Twan Keijzer, Riccardo M. G. Ferrari
Fully Homomorphic Encryption (FHE) has made it possible to perform addition and multiplication operations on encrypted data. Using FHE in control thus has the advantage that contro…
Hierarchical Cyber-Attack Detection in Large-Scale Interconnected Systems
Twan Keijzer, Alexander J. Gallo, Riccardo M. G. Ferrari
In this paper we present a hierarchical scheme to detect cyber-attacks in a hierarchical control architecture for large-scale interconnected systems (LSS). We consider the LSS as a…
Detection of Cyber-Attacks in Collaborative Intersection Control
Twan Keijzer, Fabian Jarmolowitz, Riccardo M. G. Ferrari
Road intersections are widely recognized as a lead cause for accidents and traffic delays. In a future scenario with a significant adoption of Cooperative Autonomous Vehicles, solu…
Detection of Network and Sensor Cyber-Attacks in Platoons of Cooperative Autonomous Vehicles: a Sliding-Mode Observer Approach
Twan Keijzer, Riccardo M. G. Ferrari
Platoons of autonomous vehicles are being investigated as a way to increase road capacity and fuel efficiency. Cooperative Adaptive Cruise Control (CACC) is an approach to achieve…
A Topology-Switching Coalitional Control and Observation Scheme with Stability Guarantees
Paula Chanfreut, Twan Keijzer, Riccardo M. G. Ferrari +1
In this paper a coalitional control and observation scheme is presented in which the coalitions are changed online by enabling and disabling communication links. Transitions betwee…
A Sliding Mode Observer Approach for Attack Detection and Estimation in Autonomous Vehicle Platoons using Event Triggered Communication
Twan Keijzer, Riccardo M. G. Ferrari
Platoons of autonomous vehicles are being investigated as a way to increase road capacity and fuel efficiency. Cooperative Adaptive Cruise Control (CACC) is one approach to control…
