Abstract
Specific to security issues concerning identity authentication of mobile applications, a quantum identity authentication protocol based on optical transmission and face recognition is put forward in this paper with consideration of the unconditional security characteristic of quantum key. As for this protocol, optical transmission technology is adopted to acquire quantum key and identity authentication encrypted by quantum key can thus be realized, for which key feature points of face image and user password serve as dual authentication factors. Experimental result and security analysis indicate that this protocol can resist illegal attack and ensure security of identity authentication of mobile applications, which also has great operating efficiency.

Summary
With rapid development of digitization of information in recent years, modern internet technology has been changing people’s lifestyle gradually: Various web services such as social network, long-distance education, instant messaging and ecommerce have been integrated into people’s work, study and life. With rapid development of computer technology, especially emergence of quantum computer, it becomes very difficult for the method of classic key generation and encryption to meet requirements of identity authentication in those occasions requiring a high class of confidentiality. Quantum key distribution can establish secure quantum password and realize point-to-point secure classic communication through the “one-time pad” encryption method. A quantum identity authentication protocol based on optical transmission and face recognition is put forward in this paper, for which quantum key can be acquired via wireless network instead of wired network. By using optical transmission technology, this protocol can convert a quantum key in a wired network into a QR code firstly and the user can acquire the quantum key by scanning the QR code with a mobile device. Based on a characteristic of face recognition, namely requiring no field collection of a user’s information, key feature points of a facial image and user password are used as two factors in two-factor authentication in order to realize twofactor authentication of a user’s identity and further ensure safety of network information
