From: On the use of watermark-based schemes to detect cyber-physical attacks
Numeric simulation results using the multi-watermark detection scheme. a Cumulative distribution function (CDF) of the detector under different switching frequencies. b Median detection ratio function per switching frequency, in which the shaded area corresponds to the 25 and the 75% (i.e., confidence intervals). a CDF and detection ratio per switching frequency. b Detection ratio function with respect to the switching frequency
