摘　　要：联合检测窃听的量子秘密共享协议通信效率高,对代理的能力要求低,因此受到了广泛的关注,但在实际的应用中,该协议仍面临着无法容忍信道损失以及缺乏实际安全性分析的问题.鉴于此,本文提出了一种诱骗态的联合检测窃听量子秘密共享协议.首先,我们分析了多光子信号对该协议安全性的潜在威胁,并提出了两种可能的攻击方法,有力证明了多光子信号对协议安全构成的重大影响.然后,为了削弱多光子信号的不利影响,我们提出使用诱骗态策略对协议进行改进,期望能够提升协议在非理想光源下的可靠性.最后,我们针对之前提出的两种攻击方法,对优化后的协议进行了详尽的安全性分析.结果表明,即使在非理想光源的条件下,改进后的协议也能有效抵御这两种攻击,从而确保了量子秘密共享过程的安全性和可靠性.The quantum secret sharing protocol with collective detection has garnered significant attention due to its high communication efficiency and low demands on agent capabilities.However,practical implementations face challenges such as intolerance to channel loss and insufficient practical security analysis.To address these issues,this paper proposes a decoy quantum secret sharing protocol with collective detection.First,we analyze the potential security threats posed by multi-photon signals and propose two attack methods,rigorously demonstrating their severe impact on protocol security.Subsequently,to mitigate the adverse effects of multi-photon signals,we introduce a decoy state strategy to enhance the protocol’s reliability under non-ideal conditions.Finally,detailed security analysis against the proposed attacks confirms that the improved protocol effectively resists both attacks even in non-ideal scenarios,thereby ensuring secure and reliable quantum secret sharing.
