    The invention concerns a method for making secure execution of a ROM-implanted programme (PROG) in a microprocessor-based electronic module comprising the following steps: intermittently triggering in an automatic reset timer included in the module, an interruption (IT1, IT2) in the execution of the programme (PROG); rerouting (60, 66) at each interruption (IT1, IT2), the execution of the programme to an interruption management routine (RITT) comprising, as first instruction, the instruction to return the interruption (IRET) (70) to the programme (62, 66) at the rerouting point of the interruption (IT1, IT2). The invention also concerns a microprocessor-based electronic module adapted to implement said method.
