An authentication system and device including physical unclonable function (PUF) and threshold cryptography comprising: a PUF device having a PUF input and a PUF output and constructed to generate, in response to the input of a challenge, an output value characteristic to the PUF and the challenge; and a processor having a processor input that is connected to the PUF output, and having a processor. output connected to the PUF input, the processor configured to: control the issuance of challenges to the PUF input via the processor output, receive output from the PUF output, and to carry out the following sequence of steps multiple times in connection with an instance of a desired cryptographic output. |
