一种量子密钥分发网络中的资源感知路由算法

With the development of quantum information science, the research on Quantum key distribution (QKD) network is in the ascendant. In the case of quantum key generation rate is certain, improving the quantum key utilization efficiency is of great significance for the quantum key network to be practical. To solve this problem, through the analysis of the key distribution process in trusted relay quantum key distribution network, this paper proposes a routing algorithm based on key resource aware. The performance of the system is verified by simulation. Simulation results show that compared with the classical routing algorithm, the proposed algorithm can significantly reduce the blocking probability in key distribution and improve the overall utilization of key resources.
