Abstract
A device authentication system for use with an authenticatable device having a physically-unclonable function and constructed to, in response to input, of challenge C, internally generate an output O characteristic to the PUF and the challenge C, and configured to: i) upon receiving challenge C, generate a corresponding commitment value that depends upon a private value r, and ii) upon receiving an authentication query that includes the challenge C and a nonce, return a zero knowledge proof authentication value that corresponds to the commitment value. The system comprises an enrollment server having a working verification set that includes challenge C and corresponding commitment value, wherein: a) the enrollment server is configured to generate an authentication token that corresponds to the authentication value and includes a blinded value depending upon the private value r and a random value decryptable by the authenticatable device; and/or b) the system is configured to pre-process and convey data to the authenticatable device as part of an extended Boyko-Peinado-Venkatesan generation.
