Abstract
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.
