Hata, K., Sasaki, T., Mochizuki, A., Sawada, K., Shin, S., Hosokawa, S..  2018.  Collaborative Model-Based Fallback Control for Secured Networked Control Systems. IECON 2018 - 44th Annual Conference of the IEEE Industrial Electronics Society. :5963-5970.
The authors have proposed the Fallback Control System (FCS) as a countermeasure after cyber-attacks happen in Industrial Control Systems (ICSs). For increased robustness against cyber-attacks, introducing multiple countermeasures is desirable. Then, an appropriate collaboration is essential. This paper introduces two FCSs in ICS: field network signal is driven FCS and analog signal driven FCS. This paper also implements a collaborative FCS by a collaboration function of the two FCSs. The collaboration function is that the analog signal driven FCS estimates the state of the other FCS. The collaborative FCS decides the countermeasure based on the result of the estimation after cyber-attacks happen. Finally, we show practical experiment results to analyze the effectiveness of the proposed method.
