摘　　要：提出了一个基于纠缠交换的量子安全多方求和协议,该协议允许多个参与方安全地计算其秘密数据的和.在该协议中,引入了一个半可信的第三方来帮助这些相互不信任的参与方实现这个安全任务.利用d级cat态和Bell态的纠缠交换,在参与者和半可信第三方之间安全地传输信息.最后,安全分析表明该协议对几种常见攻击的安全性,在理论上是安全的.In this paper,we present a quantum secure multi-party summation protocol,which allows multiple mutually distrustful parties to securely compute the summation of their secret data.In the presented protocol,a semi-trusted third party is introduced to help multiple parties to achieve this secure task.Besides,the entanglement swapping of d-level cat states and Bell states is employed to securely transmit message between each party and the semi-trusted third party.At last,its security against some common attacks is analyzed,which shows that the presented protocol is secure in theory.
