论文摘要
在本文中，我们提出了一个两方的半夸塔姆求和协议，其中两个古典用户可以在量子半honest第三方（TP）的帮助下完成其私人二进制序列的总和。 “半honest”一词意味着TP不能与他人合谋，但能够实施各种OOF攻击。该协议采用逻辑Qubit作为行进粒子来克服集体淘汰噪声的负面影响，并且不需要使任何两个方在共享的随机秘密密钥中。安全分析事实证明，该协议可以有效防止EVE的外部攻击以及TP的参与者攻击。此外，TP对总结结果不了解。
In this paper, we propose a two-party semiquantum summation protocol, where two classical users can accomplish the summation of their private binary sequences with the assistance of a quantum semi-honest third party (TP). The term 'semi-honest' implies that TP cannot conspire with others but is able to implement all kinds oof attacks. This protocol employs logical qubits as traveling particles to overcome the negative influence of collective-dephasing noise and needn't make any two parties pre-share a random secret key. The security analysis turns out that this protocol can effectively prevent the outside attacks from Eve and the participant attacks from TP. Moreover, TP has no knowledge about the summation results.
