In this paper, we first define a primitive protocol of secure multiparty computations to privately compute the logic operator “OR” (SMC_OR). Accordingly, we design a feasible quantum SMC_OR protocol by using single photons, which can achieve information-theoretical security in the semi-honest model. Furthermore, we adopt the proposed quantum SMC_OR protocol to solve an interesting but important privacy-preserving problem, i.e., finding the maximum value among many secrets. Finally, we simulate the related quantum protocols in Qiskit and verify the correctness and the feasibility of the proposed protocols.

求最大值的隐私保护量子协议

在本文中,我们首先定义了一个安全多方计算的原始协议,以私下计算逻辑运算符“OR”(SMC_OR)。因此,我们利用单光子设计了一种可行的量子SMC_OR协议,该协议可以在半诚实模型中实现信息论安全。此外,我们采用提出的量子 SMC_OR 协议来解决一个有趣但重要的隐私保护问题,即在许多秘密中找到最大值。最后,我们在 Qiskit 中模拟了相关的量子协议,验证了所提协议的正确性和可行性。
