论文摘要
最近，张等人。提出了一个单州半量子密钥分布协议（Int。J.Quantum Inf，18，4，2020），以帮助量子参与者与经典参与者共享秘密密钥。但是，这项研究表明，窃听者可以使用双C-Not攻击来获取最终共享密钥的一部分，而不会被参与者检测到。为了避免此问题，这里提出了修改。
Recently, Zhang et al. proposed a single-state semi-quantum key distribution protocol (Int. J. Quantum Inf, 18, 4, 2020) to help a quantum participant to share a secret key with a classical participant. However, this study shows that an eavesdropper can use a double C-NOT attack to obtain parts of the final shared key without being detected by the participants. To avoid this problem, a modification is proposed here.
