Abstract
An application device sends a key request packet to a quantum device, where the key request packet includes a user identifier corresponding to the application device, a first public key, and a first message authentication code value. If verification performed on the first message authentication code value succeeds, the quantum device sends a key response packet to the application device, where the key response packet includes a first ciphertext and a second message authentication code value. If verification performed on the second message authentication code value succeeds, the application device decrypts the first ciphertext by using a first private key, to obtain quantum key information allocated by the quantum device to the application device. The first public key and the first private key are from a key pair obtained by the application device by running a post-quantum key generation algorithm.
