SOFT MESSAGE SIGNING

摘要

A message is signed using a PUF without having to exactly regenerate a cryptographic key. Another party that shares information about the PUF is able to verify the signature to a high degree of accuracy (i.e., high probability of rejection of a forged signature and a low probably of false rejection of a true signature). In some examples, the information shared by a recipient of a message signature includes a parametric model of operational characteristics of the PUF used to form the signature.
