Zusammenfassung:The invention relates to the technical field of chaos secret communication and identity verification, in particular to an identity verification system based on a DFB chaos laser PUF and a using method thereof.The identity verification system comprises a laser, an excitation loading module, an optical PUF module, an optical signal receiving and processing module and a computer, and the optical PUF module comprises a polarization device, a DFB chaos laser and a micro-disk cavity; the DFB chaotic laser and the micro-disk cavity are connected through the arc-shaped ridge waveguide, and the output end of the computer is connected to the input end of the excitation loading module; the laser outputs an optical signal to the excitation loading module, the computer outputs a binary sequence as excitation input to the excitation loading module, and the excitation loading module sequentially inputs the modulated optical signal to the optical PUF module and the optical signal receiving and processing module. The optical
