Abstract
A countermeasure method for a microcontroller that executes sequences of instructions. The instructions are executed according to a pipeline method. At least one waiting time is randomly introduced between two consecutive instructions and/or within at least one instruction. The method is implemented by the electronics of the microcontroller rather than by software addition.
