Abstract
(EN)
The invention concerns a method for protecting data sensitive to the use of a routine acting on the data. It comprises an operation, performed by said routine, an operation which consists in verifying the identity of each software task invoking said routine (400). Preferably, said verification operation (400) comprises an operation which consists in reading an identifier of said task (304) and an operation which consists in comparing (305) said identifier with predetermined identifiers.
(FR)
Le procédé de l'invention s'applique à la protection de données sensibles à l'usage d'une routine agissant sur lesdites données. Il comporte, mise en oeuvre par ladite routine, une opération de vérification d'identité de chaque tâche logicielle appelant ladite routine (400). Préférentiellement, ladite opération de vérification (400) comporte une opération de lecture d'un identifiant de ladite tâche (304) et une opération de comparaison (305) dudit identifiant, d'une part, et d'identifiants prédéterminés, d'autre part.
