摘　　要：在BB84量子密钥分配协议中,安全密钥通常是从系统的测量结果中提取的,但在实际系统中容易受到攻击。基矢编码量子密钥分配协议的安全密钥在基矢信息中编码,不需要通过测量结果提取,该协议不涉及硬件的变换,只需对数据的后处理进行调整,因此实际系统易操作实现。针对基矢编码协议在实际系统中面临的光子束的截取重发攻击和分束攻击,文章对比分析了基矢编码、BB84和B92协议的实际安全性,分析结果表明,基矢编码协议在抵抗光子束的截取重发攻击和分束攻击方面具有更强的安全性。In BB84 quantum key distribution protocol,the security key is usually extracted from the measurement results of the system,but the actual system is vulnerable to attack.In basis encoding quantum key distribution protocol,the security key is based on the basis information,which does not need to be extracted by the measurement results.Compared with BB84 protocol,the basis encoding protocol does not change the hardware,and only needs to adjust the post-processing of the data.Therefore,the actual system is easy to implement.Aiming at the photon number splitting attack and the intercept-resend attack in the actual system,we analyze the actual security of basis coding protocol,BB84 protocol and B92 protocol.The results indicate that the basis coding protocol has better performance in fighting against the photon number splitting attack and the intercept-resend attack.
