1. A method for securing an integrated circuit during realisation thereof, said method comprising the following steps:
- delimiting of said integrated circuit into a first zone referred to as standard zone and into a second zone referred to as security zone,introducing of a layer of resin loaded with contaminant particles configured to randomly obstruct during a step of etching of the security zone a portion of the vias provided in said security zone thus forming a random set of vias, andmetalizing of said random set of vias of the security zone in order to form a random interconnection structure that defines a physical unclonable function.

Abstract
A method for securing an integrated circuit during the realization thereof, including the following steps: delimiting the integrated circuit into a first zone referred to as standard zone and into a second zone referred to as security zone, forming of a set of vias in the security zone, and introducing of a layer loaded with contaminant particles configured to randomly obstruct a portion of the vias, thus forming a random interconnection structure in the security zone, the random interconnection structure creating a physical unclonable function.

12. A secure integrated circuit, comprising:
-
a first zone referred to as standard zone comprising at least two levels of conductive tracks connected via metal interconnections to electronic components, a second zone referred to as security zone comprising a random interconnection structure formed between at least two levels of corresponding conductive patterns adapted to test the electrical continuity of said random interconnection structure and thus defining a physical unclonable function.
