Abstract
Aiming at the data tampering network attack on the fleet communication network, an attack detection method using the setter-Kalman filtering algorithm and a protection mechanism of the switching control algorithm are proposed. The method first analyzes the impact of data tampering attacks on fleet control system, and then designs an attack detection method based on the Collector-Kalman filtering algorithm under the assumption of mixed noise for the data tampering attacks, and also designs a protection mechanism for the switching control algorithm in consideration of the case that the system has been under attacks for a long period of time. Finally, through simulation experiments, it is verified that the proposed method can effectively detect the attacks on the system, and can effectively resist the adverse effects of data tampering attacks on the system, thus guaranteeing the safety of the fleet system.
