论文摘要
当网络中存在恶意攻击者时，我们需要小心窃听和污染。当网络通过量子密钥分布的部分信任继电器实现网络时，此问题对于网络通信至关重要。当存在上述攻击者时，我们讨论了线性网络中具有保密和鲁棒条件的渐近率。同样，在相同的环境下，我们仅施加保密条件时就讨论了线性网络中的渐近率。然后，我们将这些结果应用于由量子密钥分布的部分信任继电器组成的网络，这使我们能够通过短距离量子密钥分布实现安全的长距离通信。
When there exists a malicious attacker in the network, we need to be careful of eavesdropping and contamination. This problem is crucial for network communication when the network is realized by a partially trusted relay of quantum key distribution. We discuss the asymptotic rate in a linear network with the secrecy and robustness conditions when the above type of attacker exists. Also, under the same setting, we discuss the asymptotic rate in a linear network when we impose the secrecy condition alone. Then, we apply these results to the network composed of a partially trusted relay of quantum key distribution, which enables us to realize secure long-distance communication via short-distance quantum key distribution.
