An integrated circuit includes a number of components disposed at a surface of a semiconductor body and an interconnect region connecting the components into a functional circuit. A metallic shield is also produced in the interconnect region. A configurable stage is configurable to operate in a receiving antenna configuration or in a detection configuration during which the integrated circuit is configured to detect a presence of an external electromagnetic radiation representative of an attack by injection of faults.

Integrated circuit protection method, and corresponding integrated circuit

A device is provided for jamming electromagnetic radiation liable to be emitted by at least one portion of an interconnect region located above at least one zone of an integrated electronic circuit produced in and on a semiconductor substrate. The device includes an antenna located above the at least one zone of the circuit and generating circuit coupled to the antenna and configured to generate an electrical signal having at least one pseudo-random property to pass through the antenna.
