Title: METHOD AND DEVICE FOR PROTECTING AN ELECTRONIC DEVICE AGAINST FAULT ATTACK(S)
Abstract:
A protection device (PD) equips an electronic device (ED) comprising hardware and software capable of executing a sensitive process (SP). This protection device (PD) comprises i) a detection means (DM) arranged for detecting a fault effect into the electronic device (ED), resulting from at least one fault attack of an attacker during execution of the sensitive process (SP), and ii) a correction means (CM) arranged for correcting this detected fault effect before it may be detected by the attacker, so that set up of the fault be considered as missed by this attacker.
