Abstract
An electronic device randomly modifies a current profile of a logic circuit by using an auxiliary circuit. The logic circuit includes a first terminal coupled to a supply voltage terminal, a second terminal coupled to a reference voltage terminal and an output terminal configured to deliver a signal in a high state or a low state. The auxiliary circuit is coupled between the first terminal and the second terminal and is configured to randomly generate or not generate an additional current between the first terminal and the second terminal on each change of state of the signal on the output terminal.
