A method for controlling the execution of a program including of associating with each operator an initial digital code and a final digital code which are linked to each other by a degradation function applied a number of times depending on the execution of this operator; applying, to the content of a register initialized at each instruction beginning by the initial code of the corresponding operator, said degradation function a number of times depending on the operator execution; and checking, at least at each instruction end, the coherence between the register content and the final code of the corresponding operator.
