Abstract

L’invention concerne un procédé de sécurisation d’une fonction (111) mise en œuvre par un calculateur de véhicule. A cet effet, des paramètres de contrôle du véhicule sont obtenus par l’exécution de la fonction (111) dans une première couche (11) du calculateur. Les paramètres de contrôle sont vérifiés par un composant logiciel SWC exécuté dans une deuxième couche (12). Ce composant logiciel comprend une ou plusieurs unités d’exécution, chacune comprenant une première opération correspondant à une requête d’un client pour réaliser un premier contrôle d’exécution sur un serveur avant mise en œuvre de la vérification du paramètre de contrôle obtenu via l’exécution de la fonction, et une deuxième opération correspondant à une requête du client pour réaliser un deuxième contrôle d’exécution sur le serveur après mise en œuvre de la vérification.
