QUANTUM KEY DISTRIBUTION METHOD AND SYSTEM BASED ON TREE QKD NETWORK

The present disclosure relates to a quantum key distribution (QKD) method based on a tree QKD network. In a tree network, when parent nodes of a source node and a destination node are the same node, if the parent nodes are untrusted nodes, the source node and the destination node take the parent nod...

Zusammenfassung:	The present disclosure relates to a quantum key distribution (QKD) method based on a tree QKD network. In a tree network, when parent nodes of a source node and a destination node are the same node, if the parent nodes are untrusted nodes, the source node and the destination node take the parent nodes as an MDI-QKD detector to generate a key, and if the parent nodes are trusted nodes, a shared key is directly transferred through XOR relay; and when the parent nodes of the source node and the destination node are not the same node and there are discontinuous untrusted relay nodes in a transmission path, the untrusted nodes are taken as an MDI-QKD detector to generate a key, and then the shared key is transferred through XOR relay.
