Title
(EN) GENERATING AN IDENTITY FOR A COMPUTING DEVICE USING A PHYSICAL UNCLONABLE FUNCTION
(FR) GÉNÉRATION D'UNE IDENTITÉ POUR UN DISPOSITIF INFORMATIQUE À L'AIDE D'UNE FONCTION PHYSIQUE NON CLONABLE
Abstract
(EN)
A method includes: generating, by a computing device, a device secret, the generating comprising: providing, by at least one physical unclonable function (PUF), at least one value; and generating, using a key derivative function (KDF), the device secret, wherein the at least one value provided by the at least one PUF is an input to the KDF; and storing, in memory of the computing device, the generated device secret.
(FR)
Un procédé selon l'invention comprend : la génération, par un dispositif informatique, d'un secret de dispositif, la génération comprenant : la fourniture, par au moins une fonction physique non clonable (PUF), d'au moins une valeur ; et la génération du secret de dispositif, à l'aide d'une fonction de dérivation de clé (KDF), la ou les valeurs fournies par la ou les PUF étant une entrée à la KDF ; et le stockage du secret de dispositif généré, dans la mémoire du dispositif informatique.
