Quantum secret sharing (QSS) represents the fusion of quantum mechanics principles with secret information sharing, allowing a sender to distribute a secret among receivers for collective recovery. This paper introduces the concept of quantum anonymous secret sharing (QASS) to enhance the practicality of such protocols. We propose a QASS protocol leveraging W states, ensuring both recover-security and anonymity of shared secrets. Our protocol undergoes rigorous evaluation verifying their accuracy and fortifying their security against scenarios involving the active adversary. Additionally, acknowledging the imperfections inherent in real-world communication channels, we conduct a comprehensive analysis of protocol security and efficacy in noisy quantum networks. Our investigations reveal that W states exhibit good performance in mitigating noise interference, making them apt for practical applications.
量子秘密共享（QSS）将量子力学原理与秘密信息共享相结合，使发送者能够在接收者之间分发秘密以供集体恢复。本文引入量子匿名秘密共享（QASS）的概念，以提高此类协议的实用性。我们提出了一种利用W态的QASS协议，确保共享秘密的恢复安全性和匿名性。我们的协议经过了严格评估，验证了其准确性，并加强了其针对主动敌手场景的安全性。此外，认识到现实世界通信信道中固有的缺陷，我们对有噪声量子网络中协议的安全性和有效性进行了全面分析。我们的研究表明，W态在减轻噪声干扰方面表现良好，使其适用于实际应用。
