25034 该方案将 QKD 网络划分为若干路由域,并通过拓扑聚合构建分层 QKD 网络,设计了基于最低层网络匹配的跨域密钥路由算法,使得高层路由域内一跳便可跨过多个低层路由域,极大地降低了密钥中继跳数,提高了密钥交换效率及密钥资源利用率。 This routing scheme divided the QKD network into multiple routing areas, built a hierarchical network by topological aggregation and designed a cross-domain routing algorithm based on the principle of the lowest layer matching. Then the hop number in the routing path is decreased, and the efficiency of key exchange and the utilization rate of secret key materials ware increased.
