Li et al. (Quantum Inf Process 17(10):285, 2018) proposed a limited resource semi-quantum secret sharing protocol, in which the classical participants do not equip any quantum measurement devices. However, this protocol has a security loophole. This study investigates this loophole and indicates that a malicious agent can perform the double-CNOT attack to steal partial information about the secret shadow of the other agent without being detected.

有限资源半量子秘密共享的密码分析
Li等。(Quantum Inf Process 17(10):285,2018)提出了一种有限资源半量子秘密共享协议,其中经典参与者没有配备任何量子测量设备。但是,此协议存在安全漏洞。这项研究调查了此漏洞,并指出恶意代理可以执行两次CNOT攻击,以窃取有关其他代理的秘密影子的部分信息,而不会被发现。
