Abstract
The current signature of an electronic function is masked by controlling a current source that supplies power for the electronic function is controlled in a dynamically-varying manner. Excess current is detected and compared to a threshold. If the detected excess current meets the threshold, the operation of the electronic function is modified, for example by controlling a clock.
