Yu et al. and Li et al. have proposed the measure-resend protocols of authenticated semi-quantum key distribution (ASQKD). A new measure-resend ASQKD protocol is proposed in this paper, which requires a lower burden of quantum resource, needs fewer bits of the pre-shared key, and even provides better qubit efficiency than their protocols. The security proof shows the robustness of the proposed protocol under the collective attack.
