论文摘要
在本文中，我们提出了一种基于量子傅里叶变换的新型安全多方量子求和协议，其中行进粒子以树型模式传输。准备最初量子状态的当事方被认为是半honest，这意味着她可能自己行为不当，但不会与任何人合谋。提出的协议可以抵抗外部攻击和参与者攻击。特别是，一个政党无法获得其他政党的私人整数字符串；对于大多数N-2政党进行的勾结攻击，n是当事方的数量，这是安全的。此外，提出的协议计算了添加模量D，并以逐个秘密的方式实现了加法的计算，而不是逐个定位的方式。
In this paper, we propose a novel secure multi-party quantum summation protocol based on quantum Fourier transform, where the traveling particles are transmitted in a tree-type mode. The party who prepares the initial quantum states is assumed to be semi-honest, which means that she may misbehave on her own but will not conspire with anyone. The proposed protocol can resist both the outside attacks and the participant attacks. Especially, one party cannot obtain other parties' private integer strings; and it is secure for the colluding attack performed by at most n-2 parties, where n is the number of parties. In addition, the proposed protocol calculates the addition of modulo d and implements the calculation of addition in a secret-by-secret way rather than a bit-by-bit way.
