In this paper, we firstly evaluate the effect of power supply noise duet to clock signal on information acquisition to accurately acquire side-channel information from the cryptographic devices that radiates in the same frequency band as the clock signal. The result shows that the information acquisition property changes according to the duty ratio of the clock signal.
