【摘要】 研究了探测器不可信时CQKD系统的安全性问题，证明了揭露“哪个探测器响应”的要求已成为CQKD的主要漏洞。针对Alice端探测器不可信提出木马攻击方案，采用量子存储攻击方法获取密钥。针对Bob端的探测器不完美，提出了延迟光子攻击和不可见光子攻击，能够在不引入任何错误的情况下获取信息。更多还原

【Abstract】 This paper studies the security of the CQKD system when the detector is not trusted, and proves that the requirement to reveal "which detector responds" has become the main vulnerability of CQKD.A Trojan horse attack scheme is proposed for the untrustworthiness of the detector at Alice’s end, and the quantum storage attack method is used to obtain the key.The delayed photon attack and invisible photon attack are proposed for the imperfection of the detector at Bob’s end, which can obtain the information without introducing any error.更多还原
