Abstract

This paper presents a frequency-based method for detecting replay attacks and its application to a multiple tank system. This method introduces a sinusoidal signal with a time-varying frequency (authentication signature) into the closed-loop system and checks whether the output signal is compatible with the signature or not. The effectiveness of the method is illustrated through simulation scenarios using a 9-tank system under different situations.
