Therefore, it is safer to issue a warning with fewer digits than the normal number of digits.
  • control unit 15 determines whether or not a predetermined number of combinations of the operated operations match a predetermined operation content stored in the storage unit 14. However, by determining that they do not match and acquiring an arbitrary numerical value at the timing, it is possible to simplify the control without the need to acquire the numerical value in advance.

Abstract

L'invention concerne un appareil électronique et un procédé permettant de commander l'appareil électronique, destinés à améliorer la sécurité en chiffrant non seulement le contenu d'une opération mais aussi le nombre de combinaisons d'une opération pour un tiers. Une unité de commande (15) évalue si l'opération exécutée au niveau d'une unité d'opération (12) coïncide avec un contenu d'opération prédéterminé stocké dans une unité de stockage (14), autorise une opération prédéterminée s'ils coïncident l'un avec l'autre sinon évalue si le nombre d'opérations exécutées au niveau de l'unité d'opération (12) coïncide avec une valeur numérique arbitraire acquise et émet une alerte s'ils coïncident l'un avec l'autre.
