Quantum secure device, system and method for verifying challenge-response pairs using a physically unclonable function (PUF)

摘要

The present invention provides a quantum secure device, system and method for verifying challenge-response pairs using a physically unclonable function (PUF). Exemplarily, a device for verifying challenge-response pairs comprises: a wave source, in particular a light source; a challenge creating means for creating a challenge, in particular an optical challenge, to be sent to a PUF, in particular when receiving signals from the wave source; a response verifying means for verifying a response, in particular an optical response, from a PUF; and a detector for reading out the result of the verification carried out by the response verifying means. Preferably, the number of interaction particles, in particular photons, in the challenge is less than the number of parameters needed to fully describe the setting of the challenge creating means. According to a preferred embodiment, the challenge creating means and/or the response verifying means are/is adapted to carry out wavefront shaping on provided light.
