Authentication is a crucial factor in security. Authentication can be based on “what you have” or on “what you know”, i.e. traditional physical or digital keys. Both can be easily copied. The modern version of the traditional physical key is the Physical Unclonable Function (PUF): an object that cannot feasibly be copied because of the inherent randomness in its manufacture.

We have recently demonstrated a quantum-secure readout method of optical PUFs which we call “Quantum-Secure Authentication” (QSA). It is a symmetric authentication method with the advantages that it does not rely on secrets or unproven mathematical assumptions.
