Problems solved by technology

This patent realizes the identity authentication of the quantum key card when downloading the seed key, but the identity authentication method during communication is carried out between two clients who have not completed the identity authentication, so it is vulnerable to the attack of a counterfeit man-in-the-middle. security breach

Abstract

The invention provides an identity authentication method of a quantum cryptography network expansion network device, which comprises the following steps: identity authentication when an external device obtains a quantum key: authenticating network access information of the external device, after successful authentication, generating a quantum key, a server key and an external device key by a quantum cryptography network server, and sending the quantum key, the server key and the external device key to the external device; sending the quantum key and an external equipment key to the external equipment; the external device selects one key from the received quantum keys, encrypts the key by using the generated server key, generates a ciphertext, and sends the ciphertext to the quantum cryptography network server for decryption authentication. According to the invention, the security of the network access authentication information of the external device is ensured, and the identity authentication security during encrypted communication is improved.

Description

technical field [0001] The present disclosure belongs to the technical field of quantum key communication, and relates to an identity authentication method of a quantum cryptographic network expansion network device. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Quantum cryptography network is an emerging security network. It includes two kinds of networks: classical communication networks (classical internet or mobile internet) and quantum key distribution (QKD) networks. The QKD network generates quantum keys, and the classical communication network uses the quantum keys generated by the QKD network for quantum secure communication. Terminals or servers in a quantum cryptographic network can communicate with quantum security through the shared quantum key, which is equivalent to having a quantum security communication link between t...
