Abstract: This paper discusses the quantum one-way function and the information-splitting principle, proposes an identity authentication and key distribution protocol. It uses the trusted server provides random dentity and completes the final confirmation of the protocol. Key distribution is interspersed in the authentication process. Quantum one-way function can improve the authentication security. Experimental results show that the quantum communication technology about the protocol is easy to implement and can improve the efficiency of key distribution.

Key words: quantum cryptography, quantum identity authentication, key distribution, quantum one-way function, information segmentation, polarization state
