Quantum Identity Authentication in the Counterfactual Quantum Key Distribution Protocol

Bin Liu, Zhifeng Gao, Di Xiao +3 more

In this paper, a quantum identity authentication protocol is presented based on the counterfactual quantum key distribution system. Utilizing the proposed protocol, two participants can verify each other's identity through the counterfactual quantum communication system. The security of the protocol is proved against individual attacks. Furthermore, according to the characteristics of the counterfactual quantum key distribution system, we propose an authenticated counterfactual quantum key distribution protocol based on a novel strategy of mixing the two types of quantum cryptographic protocols randomly. The authenticated quantum key distribution can also be used to update the extent of the authentication keys.

A Quantum Identity Authentication Protocol Based on Optical Transmission & Face Recognition

Dexin Zhu, Xiaohui Li, Xiaohong Li +3 more

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.
