Title (EN) MAGNETIC HELICAL PHYSICAL UNCLONABLE FUNCTION MEASURED ABOVE FLIGHT
(FR) FONCTION PHYSIQUE NON CLONABLE HÉLICOÏDALE MAGNÉTIQUE MESURÉE AU-DESSUS D'UNE SPIRE
Abstract:
(EN) A helical physical unclonable function is disclosed. The helical physical unclonable function may be used to authenticate a supply item for an imaging device. Measurements of the magnetic field above a helical flight are stored in a non-volatile memory to be used by an imaging device to authenticate the supply item. Other systems and methods are disclosed.
(FR) L'invention concerne une fonction physique non clonable hélicoïdale. La fonction physique non clonable hélicoïdale peut être utilisée pour authentifier un article d'approvisionnement pour un dispositif d'imagerie. Les mesures du champ magnétique au-dessus d'une spire hélicoïdale sont stockées dans une mémoire non volatile destinée à être utilisée par un dispositif d'imagerie pour authentifier l'article d'approvisionnement. L'invention concerne également d'autres systèmes et d'autres procédés.
