Abstract
The application provides a key distribution method, a key receiving method, equipment and a medium, and relates to the technical field of optical fiber communication. The method is applied to a quantum key distribution device; the quantum key distribution device is used for generating a quantum key; the method comprises the following steps: encrypting a service key by using a shared key to obtain an encrypted service key; the quantum key generated by the quantum key distribution device comprises the shared key and the service key; the encrypted service key is sent to a first device; the shared key is preset on the first device and is used for the first device to decrypt the encrypted service key; and the service key is used for the first device to encrypt or decrypt transmission data between the first device and a second device. Through the above method, the transmission of the quantum key as the service key is ensured to be safe.
