| 摘 要： | 在分布式计算系统中，拜占庭协议是解决其容错问题的一种实用方法。拜占庭问题有一种演变形式，称之为检测的拜占庭协议。这类协议在经典世界中无法解决容错问题，但在量子系统中利用纠缠态却可以。GBKCW协议是一种典型的量子检测拜占庭协议。针对GBKCW协议中数据列表的生成和分发部分，利用量子纠缠态的确定性，探测了参与者共享的量子态，以抵御针对GBKCW的截获重发攻击。

| Abstract: | In distributed computing,Byzantine agreement is a practical method to solve its fault-tolerance problem.There is a variation of the Byzantine agreement which is called detectable Byzantine agreement.This kind of protocol is unsolvable by classical means,but can be solved using quantum resources——quantum entangled states.A typical quantum detectable Byzantine agreement is the GBKCW protocol.The part with the generation and distribution of the lists in the GBKCW protocol was dealed with.In order to keep the GBKCW protocol from the intercept-and-resend strategy,the property of the determination of entangled states were employed to test the sharing state between the parties. |
