Title
(EN) DEVICE AUTHENTICATION BASED ON ANALOG CHARACTERISTICS WITHOUT ERROR CORRECTION
(FR) AUTHENTIFICATION DE DISPOSITIF BASÉE SUR DES CARACTÉRISTIQUES ANALOGIQUES SANS CORRECTION D'ERREUR
Abstract
(EN) This application describes systems and methods for using a physical unclonable function (PUF) to authenticate a device, which may include circuitry for generating PUF values that may uniquely identify the device. According to one aspect, the device may provide enrollment PUF values to an authentication device. The device may later be authenticated if PUF values generated by the device are within a threshold distance of the enrollment PUF values. Since the PUF values are compared using a distance, it may not necessary to apply an error correcting code to the PUF values. The enrollment values and/or the calculated distance may be adjusted to compensate for time variations in the PUF values due to circuit aging. Systems and methods are also described herein for authenticating the device without revealing new PUF values to any second party, for example using a cryptographic technique known as a garbled circuit.
(FR) L’invention concerne des systèmes et des procédés permettant d’utiliser une fonction non clonable physique (PUF) pour authentifier un dispositif, qui peut comprendre un circuit permettant de générer des valeurs PUF pouvant identifier le dispositif de manière unique. Selon un aspect, le dispositif peut fournir des valeurs PUF d'inscription à un dispositif d'authentification. Le dispositif peut être authentifié ensuite si les valeurs PUF générées par le dispositif se trouvent à une distance seuil des valeurs PUF d'inscription. Comme les valeurs PUF sont comparées à l'aide d'une distance, il n'est pas nécessaire d'appliquer un code de correction d'erreur aux valeurs PUF. Les valeurs d'inscription et/ou la distance calculée peuvent être ajustées pour compenser les variations temporelles des valeurs PUF dues au vieillissement du circuit. L'invention concerne également des systèmes et des procédés permettant d'authentifier le dispositif sans révéler de nouvelles valeurs PUF à une quelconque seconde partie, par exemple à l'aide d'une technique cryptographique connue sous la forme d'un circuit tronqué.
