Abstract[English]
There is described methods and devices for generating and utilizing a physical unclonable function (PUF) key. A hardware source is read to obtain a hardware output of a unique identifier of the hardware source. One of a plurality of hardware PUF methods is selected, each of the plurality of hardware PUF methods adapted to a respective hardware source type. The PUF key is generated from the hardware output using the selected hardware PUF method.[French]
L'invention concerne des procédés et dispositifs permettant de générer et d'utiliser une clé de fonction non clonable physique (PUF). Une source matérielle est lue pour obtenir une sortie matérielle d'un identifiant unique de la source matérielle. Un procédé PUF de matériel parmi une pluralité de procédés PUF de matériel est sélectionné, chaque procédé PUF de matériel parmi la pluralité de procédés PUF de matériel étant adapté à un type de source matérielle respectif. La clé PUF est générée à partir de la sortie matérielle à l'aide du procédé PUF de matériel sélectionné.
