摘要：
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.
