METHOD FOR DETECTING AN ATTEMPTED ATTACK, RECORDING MEDIUM, AND SECURITY PROCESSOR FOR SAID METHOD.

摘要

The invention relates to a method for detecting an attempted attack of a security processor by the security processor itself, including: measuring (50) a plurality of separate events taking place independently of one another in the absence of an attempted attack; constructing (52) the value of at least one attack indicator in accordance with at least one concomitance index between at least two separate measured events, the concomitance index representing the proximity in time of the two separate measured events; and detecting (54) an attempted attack if the value of the attack indicator exceeds a predetermined threshold.
