Quantum key distribution is an important way of quantum communication. In order to improve the feasibility, security and efficiency of quantum key distribution, a mutual authenticated multiparty quantum key distribution protocol based on single particle state is proposed. In this protocol, any two users in a quantum network can perform mutual authentication and share a secure session key with the assistance of a semi-trusted third party. The particles used as quantum information carriers are not required to be stored, which is easier to implement under current technology. The security analysis shows that the proposed protocol is secure in theory.
