Deconvolving Protected Signals

Abstract—The variable clock (VC) side-channel countermeasure consists in clocking a chip with an internal oscillator whose parameters (frequency, duty cycle, shape etc.) vary randomly in time. In this paper, we use parametric deconvolution to process VC-power consumption curves. We also analyze experimental results in order to show its efficiency.
