Title (EN) GENERATOR OF PHYSICALLY UNCLONABLE CRYPTOGRAPHIC KEYS
(FR) GÉNÉRATEUR DE CLÉS CRYPTOGRAPHIQUES PHYSIQUEMENT NON CLONABLES
Abstract:
(EN) Generator of physically unclonable cryptographic keys (PUF) has two adjustable speed ring oscillators (GPRS, GPRS'), which outputs (o-GPRS, o-GPRS') are connected to inputs (il-DF, i2-DF) of a phase detector (DF), which output (o-DF) is connected to control inputs of the adjustable speed ring oscillators (s-GPRS, s-GPRS' ) through a control system (US) and is also connected to a output (o-PUF) of the generator of physically unclonable cryptographic keys (PUF) through a sample and compare circuit (URP). Generator has a initializing input (i-UCH) connected to both initializing inputs of the adjustable speed ring oscillators (i-GPRS, i-GPRS' ) and to the first input of the sample and compare circuit (i-URP), which second input (z-URP) is connected to the output (o-GPRS') of one of adjustable speed ring oscillators (GPRS').
(FR) L’invention concerne un générateur de clés cryptographiques physiquement non clonables (PUF) qui comprend deux oscillateurs en anneau à vitesse réglable (GPRS, GPRS'), dont les sorties (o-GPRS, o-GPRS ') sont reliées à des entrées (il-DF, i2-DF) d'un détecteur de phase (DF), dont la sortie (o-DF) est reliée à des entrées de commande des oscillateurs en anneau à vitesse réglable (s-GPRS, s-GPRS') par l'intermédiaire d'un système de commande (US) et est également reliée à une sortie (o-PUF) du générateur de clés cryptographiques physiquement non clonables (PUF) par l'intermédiaire d'un circuit d'échantillonnage et de comparaison (URP). Le générateur comporte une entrée d'initialisation (i-UCH) reliée à la fois aux entrées d'initialisation des oscillateurs en anneau à vitesse réglable (i-GPRS, i-GPRS') et à la première entrée du circuit d'échantillonnage et de comparaison (i-URP), ladite seconde entrée (z-URP) étant reliée à la sortie (o-GPRS') de l'un des oscillateurs en anneau à vitesse réglable (GPRS').
