论文摘要
最近，Yang等人。 （量子INF进程18，74，2019）提出了集体噪声通道上的两党量子密钥协议协议。他们声称他们的量子密钥协议协议可以确保两个参与者对最终共享密钥的影响相等。但是，这项研究表明，宣布置换操作的参与者可以在不被对方检测到的情况下操纵自己/她自己的最终共享密钥。为了避免此漏洞，这里提出了改进。
Recently, Yang et al. (Quantum Inf Process 18, 74, 2019) proposed a two-party quantum key agreement protocol over a collective noisy channel. They claimed that their quantum key agreement protocol can ensure both of the participants have equal influence on the final shared key. However, this study shows that the participant who announces the permutation operation can manipulate the final shared key by himself/herself without being detected by the other. To avoid this loophole, an improvement is proposed here.
