论文摘要
在本文中，我们估计如何通过一个，两个，即连接密度）引入具有信任节点串行连接的量子网络之间的其他连接会影响其安全性。我们为整个量子网络的水平提供了适当的身份验证概率和量子密钥分布协议的适当缩放。导出了每个元素的平均故障概率的用户之间连接节点的总数和连接密度之间的总数。结果提供了在关键运输安全性的提高和随之而来的消费资源增加之间的明确权衡。我们认为，获得的结果对于未来网络的设计和现有网络的优化可能很有用。
In this paper we estimate how introduction of additional connections between trusted nodes through one, two and so on (i.e. connection density) to a quantum network with serial connection of trusted nodes affects its security. We provide proper scaling of failure probability of authentication and quantum key distribution protocols to the level of the whole quantum network. Expressions of the failure probability dependent on the total number of connected nodes between users and connection density for given mean failure probability of each element are derived. The result provides explicit trade-off between increase of the key transport security and consequent increase of spent resources. We believe that obtained result may be useful for both design of future network and optimization of existing ones.
