Quantum security authentication system based on optical PUF

The invention aims at problems in an existing PUF authentication system, and provides a quantum security authentication system based on an optical PUF. According to the quantum security authentication system, coherent light or a single-photon source after height attenuation is used as a light source. A spatial light modulator is used for performing wavefront modulation on incident light for obtaining a large amount of excitation-response pairs, thereby ensuring information amount and security of the authentication system. A wavefront feedback control program is used for indirectly obtaining wavefront information of response light. Furthermore the position of the PUF is accurately positioned through an excitation-response pair auxiliary calibration method, thereby greatly reducing complexity of system structure. The quantum security authentication system has advantages of improving authentication safety, reducing system use requirement, simplifying system structure and realizing good application prospect in the security authentication field.
