Abstract
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
Claims20
A method comprising:
- experiencing, at an integrated circuit, an attack by injection of faults via an external electromagnetic radiation;
- and|
- using a metallic shield to detect the external electromagnetic radiation, the integrated circuit comprising the metallic shield disposed in an interconnection region of the integrated circuit.
An integrated circuit comprising:
- a plurality of components disposed at a surface of a semiconductor body;
- an interconnect region connecting the components into a functional circuit;
- and
- a protection device comprising a detector produced in the interconnect region, wherein the detector comprises a metallic shield and is configured to detect a presence of an external electromagnetic radiation representative of an attack by injection of faults.
