The invention relates to a method of verifying the integrity of a software application that can be executed on a host terminal. The inventive method comprises the following steps consisting in: (i) determining at least one series of control instructions forming an executable certificate (4, 15) for the software application, which can be executed by the host terminal during the execution of the software application to be verified (1, 11); (ii) on the host terminal, executing the software application to be verified (1, 11), receiving the executable certificate (4, 15) determined during step (i) and executing the series of control instructions for the certificate which can be executed in the memory context of said host terminal; (iii) comparing the result thus obtained through the execution of the control instructions with the result expected from an authentic software application; and (iv) in the event of a positive comparison, continuing with the execution of the software application to be verified (1, 11).
Le procédé de vérification de l'intégrité d'une application logicielle exécutable dans un terminal hôte, comprend les étapes suivantes i) déterminer au moins une suite d'instructions de contrôle formant certificat exécutable (4,15) pour l'application logicielle, exécutable par ledit terminal hôte au cours de l'exécution de l'application logicielle à vérifier (1,11), ii) sur le terminal hôte, exécuter l'application logicielle à vérifier (1,11), recevoir le certificat exécutable (4,15) ainsi déterminé lors de l'étape i) et exécuter la suite d'instructions de contrôle dudit certificat exécutable dans le contexte mémoire dudit terminal hôte, iii) comparer le résultat ainsi obtenu par l'exécution des instructions de contrôle avec le résultat attendu d'une application logicielle authentique et, iv) en cas de comparaison positive, continuer le cours de l'exécution de l'application logicielle à vérifier (1,11).
