A device for verifying at least one challenge-response pair includes a coherent light source configured to emit coherent light. A challenge creating device is configured to create an optical challenge to be sent to a physically unclonable function (PUF). A wavefront shaping device is configured to perform a verification based on an optical response from the physically unclonable function (PUF). A detector is configured to read out a result of the verification performed by the wavefront shaping device. A focusing device is configured to focus light exiting from the wavefront shaping device onto the detector for detection.
