Security and privacy have always been key concerns for individuals in various edge-assisted services. In this paper, we present a feasible quantum solution to an important primitive of secure multiparty computations, i.e., Secure Multiparty Logical AND (SMLA), in which participants can securely compute logical AND of private bits. In order to ensure perfect security and achieve good feasibility, we introduce a semi-honest edge server and two non-collusive fog nodes, and design a secure and feasible edge-assisted quantum protocol for SMLA, which cleverly utilizes Secure Multiparty XOR to implement SMLA group by group. Furthermore, we focus on applications of this quantum primitive protocol and design two quantum protocols for Multiple Private Set Intersection and Anonymous One-vote Veto. Compared with classical related protocols, our proposed quantum protocols obtain higher security, which can be guaranteed by the basic principles of quantum mechanics.
安全和隐私一直是各种边缘辅助服务中个人关注的关键问题。在本文中，我们针对安全多方计算的一个重要原语，即安全多方逻辑与（SMLA），提出了一种可行的量子解决方案，其中参与者可以安全地计算私有比特的逻辑与。为了确保完美的安全性并实现良好的可行性，我们引入了一个半诚实的边缘服务器和两个非勾结的雾节点，并设计了一个用于SMLA的安全可行的边缘辅助量子协议，该协议巧妙地利用安全多方异或逐组实现SMLA。此外，我们专注于这种量子原语协议的应用，并设计了两个用于多个私有集交集和匿名一票否决的量子协议。与经典相关协议相比，我们提出的量子协议具有更高的安全性，这可以由量子力学的基本原理保证。
