Disclosed is a mobile secret communications method based on a quantum key distribution network, comprising the following steps: a mobile terminal registering to access the network and establishing a binding relationship with a certain centralized control station in the quantum key distribution network; after a communication service is initiated, the mobile terminals participating in the current communication applying for service keys from the quantum key distribution network; the quantum key distribution network obtaining addresses of the centralized control stations participating in service key distribution during the current communication, designating a service key generation centralized control station according to a current state indicator of each centralized control station; the service key generation centralized control station generating service keys required in the current communication and distributing the keys to the mobile terminals participating in the current communication; the mobile terminals participating in the current communication using the service keys and performing secret communication through an original data link of such a communication service. The present invention makes improvement to the existing solution of a service key generation phase and a key relay phase, and solves the problem that the service quality is affected when there are a large number of relay nodes and after the arrival of the key lags. |
