Embodiments of this application relate to the field of communications technologies. The embodiments of this application are applicable to a centralized management and control network. A centralized controller obtains Z service requests, globally determines, based on an identifier of a source service node and an identifier of a destination service node that are corresponding to each of the Z service requests, a quantum key consumption parameter, and topology information of key nodes in the centralized management and control network, globally optimal key relay instructions corresponding to G service requests, and further delivers the key relay instructions corresponding to the G service requests to key nodes corresponding to the key relay instructions, so that the key nodes perform quantum key relay based on the key relay instructions, to generate a shared quantum key between the source key node and the destination key node.

Quantum key relay method based on centralized management and control network, and apparatus

This application provide quantum key distribution methods, devices, and storage media. In an implementation, a method comprises: determining, based on a first mapping, a first quantum key of N first quantum keys corresponding to an inode on a target routing path; determining, based on a second mapping, a second quantum key of N second quantum keys corresponding to the inode; and generating, by the inode based on the first quantum key corresponding to the inode and the second quantum key corresponding to the inode, a third quantum key corresponding to the inode on the target routing path.
