Abstract

One aspect of an embodiment of the invention provides a method, system, and device to prove to a challenger that a prover device has a signature from a device manufacturer without revealing the signature to the challenger. According to one implementation, a challenger is provided with the result of a one-way function of a secret held by a prover device. An interactive proof is employed, between the prover device and the challenger, to prove to the challenger that the secret used in the one-way function has been signed by a device signature without revealing the secret or the device signature or the prover device's identity to the challenger.
