Abstract
The supply voltage for a module of an integrated circuit managed to support protection against side channel attacks. Upon startup of the integrated circuit, one action from the following actions is selected in response to a command: supplying the module with the supply voltage having a fixed value that is selected from a plurality of predetermined values, or varying the value of the supply voltage in time with a pulsed signal.
