ABSTRACT
ABSTRACT. Quantum key distribution (QKD) network develops rapidly in recent years. In order to improve the efficiency and security of quantum key distribution, this paper analyzes the advantages and disadvantages of single-path and multi-path quantum key distribution and proposes a multi-path quantum key distribution scheme. This scheme includes two aspects which are path equalization priority strategy and the No-public nodes strategy. The priority of the chosen path is based on the path bandwidth utilization, the number of routing hops and quantum keys stored in the trusted nodes. The no-public nodes strategy selects multiple key distribution paths without public nodes. The scheme can reduce the risk of path blocking and the consumption of quantum keys, improve the efficiency and security of QKD. Finally, this scheme is analyzed and verified.
