“…As a result, the new protocol was revised to address this issue [31]. In 2022, SQPC protocols based on single particle states, Bell states or GHZ states were proposed successively [32][33][34]. Ye and Lian proposed two MSQPC protocols based on d-dimensional single-particle states and d-dimensional Bell states [35,36].…”

Semi-quantum private comparison is a method for private comparison with fewer quantum resources, enabling classical participants to collaborate with a semi-honest third party possessing complete quantum capabilities. A one-way quantum private comparison protocol is devised only by unitary operations. The protocol facilitates one-way transmission between third party (TP) and classical participants in quantum communication, where the classical participants only need to perform unitary operations and measurement operations on the transmitted qubits. In addition, classical participants do not require pre-shared keys. It is shown that the qubit efficiency of this protocol is 12.5%. Finally, security analysis and the simulation results on the IBM Quantum Experience demonstrate the security and the feasibility of this protocol.

“…Since then, many SQSDC protocols with an entanglement state [ 61 , 62 , 63 , 64 , 65 , 66 , 67 , 68 ] and without entanglement [ 69 ] have been proposed. Private comparison is primitive for many cryptographic tasks, and recently, several schemes for semi-quantum private comparison with single photons [ 70 , 71 , 72 , 73 ], Bell states [ 74 , 75 , 76 , 77 ], GHZ-like states [ 78 , 79 , 80 ], and W states [ 81 ] have been proposed.…”

Recently, Zhao et al. proposed a semi-quantum bi-signature (SQBS) scheme based on W states with two quantum signers and just one classical verifier. In this study, we highlight three security issues with Zhao et al.’s SQBS scheme. In Zhao et al.’s SQBS protocol, an insider attacker can perform an impersonation attack in the verification phase and an impersonation attack in the signature phase to capture the private key. In addition, an eavesdropper can perform a man-in-the-middle attack to obtain all of the signer’s secret information. All of the above three attacks can pass the eavesdropping check. Without considering these security issues, the SQBS protocol could fail to ensure the signer’s secret information.
