Abstract
An integrated circuit and a method of securing the integrated circuit during its fabrication. The method includes delimitation of the integrated circuit into a first zone called a standard zone and a second zone called a security zone, and random degradation of an interconnection structure of the security zone thus forming a physical unclonable function modelled by random electrical continuity that can be queried by a challenge-response authentication protocol.
