Abstract
An integrated circuit including an intrusion attack detection device. The device includes a single-piece formed of a conductive material and surrounded with an insulating material and includes at least one stretched or compressed elongated conductive track, connected to a mobile element, at least one conductive portion distant from said piece and a circuit for detecting an electric connection between the piece and the conductive portion. A variation in the length of said track in an attack by removal of the insulating material, causes a displacement of the mobile element until it contacts the conductive portion.
