Title
(EN) UNCLONABLE SECURITY FOR ADDITIVE MANUFACTURING USING MATERIAL DESIGNED FOR A PHYSICAL UNCLONABLE FUNCTION
(FR) SÉCURITÉ NON CLONABLE POUR LA FABRICATION ADDITIVE À L'AIDE D'UN MATÉRIAU CONÇU POUR UNE FONCTION PHYSIQUE NON CLONABLE
Abstract
(EN)
Disclosed is a process of adding PUF materials with non-repeatable random order to the additive manufacturing process of a product. Preferably, these materials have magnetic characteristics. These characteristics can be detected by a sensor which reads the random pattern and provides a unique signature for the item produced.
(FR)
Cette invention concerne un procédé d'ajout de matériaux à fonction physique non clonable selon un ordre aléatoire non répétable lors du processus de fabrication additive d'un produit. De préférence, ces matériaux ont des caractéristiques magnétiques. Ces caractéristiques peuvent être détectées par un capteur qui lit le motif aléatoire et fournit une signature unique pour l'article produit.
