Abstract: Disclosed is a method for allocating QKD network resources, which includes the following steps: obtaining a network structure of a QKD network, and constructing a key topology according to distributions condition of quantum key resources in the QKD network; in response to arrival of a service requiring encryption, judging whether the encrypted service is delay sensitive; when the service is delay sensitive, distributing quantum key resources to the service according to the key topology of the QKD network; and when the service is not delay sensitive, distributing quantum key resources to the service according to the network structure of the QKD network. Moreover, the present disclosure also provides a device for allocating QKD network resources and a non-transitory computer-readable storage medium.
