Attack detection method for encrypted wave‐variable‐based bilateral control systems

IET Control Theory &Applications, Volume 18, Issue 11, Page 1461-1474, July 2024.
This study presents an energy‐based attack detection method involving an encrypted bilateral control system using wave variables. This study provides a specific design for reasonable threshold parameters concerning the energy of the control system. The theorem and the experimental validation confirm that the developed encrypted wave‐variable‐based ...
