Title (EN) INTEGRATED DEVICE FOR IMPLEMENTING A PHYSICAL UNCLONABLE FUNCTION AND A PHYSICAL UNCLONABLE CONSTANT
(FR) DISPOSITIF INTÉGRÉ POUR IMPLÉMENTER UNE FONCTION NON CLONABLE PHYSIQUE ET UNE CONSTANTE NON CLONABLE PHYSIQUE
Abstract:
(EN) A PUC (Physical Unclonable Constant) cell characterized by a very low complexity comparable to that of an SRAM cell and by much greater reliability than an SRAM cell as it is characterized by only one stable equilibrium point the position of which depends on random differences introduced during the step of manufacturing the chip. The PUC cell according to the present invention is also stable over a wide range of operating temperatures and offers considerable noise immunity, thus making the use of stabilizers adapted to ensure the correct output and which are normally used along with conventional SRAM type cells unnecessary.
(FR) L'invention concerne une cellule PUC (constante non clonable physique) caractérisée par une très faible complexité comparable à celle d'une cellule SRAM et par une fiabilité bien supérieure à celle d'une cellule SRAM car elle est caractérisée par un seul point d'équilibre stable dont la position dépend de différences aléatoires introduites pendant l'étape de fabrication de la puce. La cellule PUC selon la présente invention est également stable sur une large plage de températures de fonctionnement et offre une considérable immunité au bruit, ce qui rend superflue l'utilisation de stabilisateurs conçus pour assurer la sortie correcte et qui sont normalement utilisés avec des cellules de type SRAM classiques.
