Abstract

The invention relates to a quantum network-based secret key charging method and a quantum network-based secret key charging system. The method comprises: secret key application layer equipment sends an authentication network access instruction to secret key management layer equipment, the secret key management layer equipment verifies the legality of the secret key application layer equipment according to the authentication network access instruction and feeds back a response command, and the secret key application layer equipment receives the successful response command and accesses a quantumnetwork; the secret key application layer equipment sends a secret key acquisition instruction to the secret key management layer equipment; the key management layer equipment judges whether key output is allowed or not according to the key acquisition instruction, controls key output of the home terminal key management layer equipment and the opposite terminal key management layer equipment according to a judgment result, generates key charging list format data from key output related information and sends the key charging list format data to the auxiliary system; and the auxiliary system updates the residual output key quantity of the key application layer equipment corresponding to the auxiliary system according to the received key charging list format data, and performs quantum key charging.

Description

technical field [0001] The invention belongs to the technical field of quantum communication, and in particular relates to a key accounting method and system based on a quantum network. Background technique [0002] With the development of network information, the network affects all aspects of people's lives, and the subsequent security requirements are getting higher and higher, and the confidentiality requirements for people's network activities are also getting higher and higher. Encryption or authentication technology meets people's requirements for keeping their own data and some related materials confidential in network activities, and ensures the security and confidentiality of the network. Due to its unconditional security and high efficiency, quantum communication has brought a revolutionary development to information security, and is currently the main research direction for secure data transmission. [0003] Such as figure 1 As shown, the current quantum commun...
