论文摘要
在量子网络系统中，这是自然的，多个用户打算将其量子消息发送给各自的接收器，该消息称为多个单播量子网络。我们提出了一种规范方法，可以从安全的经典网络代码通过多个单播量子网络得出安全的量子网络代码。当没有攻击时，我们的代码正确传输量子状态。它还保证了传输量子状态的保密性，即使在攻击满足某种自然状况时攻击存在攻击也是如此。在我们的安全证明中，允许窃听器根据先前窃听的消息对窃听信息进行修改。我们的协议通过与量子网络相同的方向利用单向古典信息传输（公共通信）来保证保密，尽管量子信息传输的验证需要双向经典通信。我们的安全网络代码可以应用于包括蝴蝶网络在内的多个网络。
It is natural in a quantum network system that multiple users intend to send their quantum message to their respective receivers, which is called a multiple unicast quantum network. We propose a canonical method to derive a secure quantum network code over a multiple unicast quantum network from a secure classical network code. Our code correctly transmits quantum states when there is no attack. It also guarantees the secrecy of the transmitted quantum state even with the existence of an attack when the attack satisfies a certain natural condition. In our security proof, the eavesdropper is allowed to modify wiretapped information dependently on the previously wiretapped messages. Our protocol guarantees the secrecy by utilizing one-way classical information transmission (public communication) in the same direction as the quantum network although the verification of quantum information transmission requires two-way classical communication. Our secure network code can be applied to several networks including the butterfly network.
