摘要: In paper [Chin. Phys. B 32 070308 (2023)], Xing et al. proposed a semi-quantum secret sharing protocol by using single particles. We study the security of the proposed protocol and find that it is not secure, that is, the three dishonest agents, Bob, Charlie and Emily can collude to obtain Alice's secret without the help of David.

关键词: security loophole, rearranging orders, semi-quantum secret sharing, single particles
