Abstract

Procédé de production d'une suite (404') d'instructions pour une unité informatique qui peut être commandée par un programme, dans lequel des valeurs (SIG , SIG' ) de signature sont calculées sur la base des instructions (I , I , I , I , I , I ) exécutées et sont comparées à des valeurs de référence qui comprend la détermination d'une valeur (SIG ) de signature cible ; la détermination d'une suite (404) d'instructions initiale menant en un point (P) du programme, l'exécution de la suite (404) initiale d'instructions à partir d'une valeur de signature de début ayant pour conséquence le calcul d'une valeur (SIG ) initiale de la signature cible ; et la détermination d'une modification de la suite (404) initiale d'instructions pour obtenir une suite (404') modifiée d'instructions.
