Abstract
In a general aspect, a countermeasure method implemented in a microcircuit can include selecting, at each cycle of a clock signal, a supply mode of a component internal to the microcircuit, the supply mode can be selected from among a first supply mode in which the component is fully supplied by a first supply circuit connected to a supply input of the microcircuit, and at least one second supply mode in which the component is at least partially supplied by a second supply circuit internal to the microcircuit. The second supply circuit can be isolated from the exterior of the microcircuit while it is supplying the component.
