Abstract

This study proposes the first multiparty-to-multiparty mediated quantum secret sharing (M2M-MQSS) protocol within a restricted quantum environment. Unlike existing fully quantum secret sharing (QSS) protocols, this protocol allows protocol participants with limited quantum capabilities—including (1) measuring a single qubit in the Z-basis and (2) performing a single-qubit unitary operation, Hadamard operation—to participate, significantly reducing implementation costs. By employing one-way qubit transmission, the proposed MMQSS protocol not only simplifies the quantum communication process but also effectively defends against quantum Trojan horse attacks. The correctness and security analyses demonstrate that the proposed M2M-MQSS protocol is robust against various well-known attack strategies. Simulation experiments confirm the feasibility of the protocol for various numbers of participants. It maintains high levels of efficiency and security even as the number of participants increases. Moreover, compared with existing protocols, the proposed M2M-MQSS protocol lowers the barrier to practical quantum communication deployment by reducing the quantum resources required for protocol participants.

受限量子环境下多方对多方中介的量子秘密共享协议
本研究提出了在受限量子环境下的第一个多方对多方介导的量子秘密共享(M2M-MQSS)协议。与现有的全量子秘密共享(QSS)协议不同,该协议允许具有有限量子能力的协议参与者(包括(1)在z基中测量单个量子位,(2)执行单个量子位的单一操作,Hadamard操作)参与,从而显着降低了实施成本。MMQSS协议采用单向量子比特传输,不仅简化了量子通信过程,而且有效防御了量子特洛伊木马攻击。正确性和安全性分析表明,所提出的M2M-MQSS协议对各种已知的攻击策略具有鲁棒性。仿真实验验证了该协议在不同参与者数量下的可行性。即使参与者数量增加,它也能保持高水平的效率和安全性。此外,与现有协议相比,所提出的M2M-MQSS协议通过减少协议参与者所需的量子资源,降低了实际量子通信部署的障碍。
