1. A method for proving authenticity of a prover PRV to a verifier VER, the method comprising the following steps:

  • generating, by the prover PRV, a secret S using a physical token PUF,obtaining, by the verifier VER, a public value PV which has been derived from the secret S using a function F, and where the function F is selected such that it is computationally expensive to establish the secret S given the public value PV, andconducting a zero knowledge protocol between the prover PRV and the verifier VER in order to prove to the verifier VER, with a pre-determined probability, that the prover PRV has access to the physical token PUF, where the prover PRV makes use of the secret S and the verifier VER makes use of the public value PV.
