  • PROTECTIVE METHOD OF AN ELECRONIC DEVICE AGAINST ATTACKS BY FAULT INJECTION
    Publication number: 20190050565
    Abstract: The present invention relates to a method for protection of an electronic device (1) against attacks by fault injection, the method comprising steps of detection of anomalies likely to inject a fault in the electronic device (1) or be caused by a fault injection in the electronic device (1), incrementation (206) by an anomaly counter (cpt_velo, cpt_tearing) as a function of the detected anomalies, comparison (208) between the anomaly counter (cpt_velo, cpt_tearing) and a first threshold (seuil_cpt_velo, seuil_cpt_tearing), performing a protective measure (210) of the electronic device (1) when the number of counted anomalies reaches the predetermined threshold, the method being characterized in that the anomaly counter (cpt_velo, cpt_tearing) is incremented (206) only in case of detection of: a number of anomalies greater or equal to a second threshold (seuil_cpt_hist) strictly less than the first threshold (seuil_cpt_velo, seuil_cpt_tearing) over a period during which a predetermined number (N) of
