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.
