Data transmission method and device based on quantum communication

Abstract

The invention discloses a data transmission method based on quantum communication, being applied to a first communication end. The method includes the steps of encrypting the target data with a first conventional key; sending the obtained first encrypted data to a second communication end, so that the second communication end decrypts the first encrypted data by using the first traditional key to obtain the target data; performing the quantum encryption processing on the conventional key set in a first key pool using the quantum key by means of the first communication end, sending the obtained second encrypted data to the second communication end, so that the second communication end decrypts the second encrypted data with the quantum key to obtain the conventional key set including a first conventional key. According to the invention, the key size of the quantum secure communication system is improved, the normal operation of quantum secure communication system can be guaranteed. The invention further discloses a data transmission device based on quantum communication, which has the corresponding technological effects.

Description

technical field [0001] The invention relates to the technical field of quantum communication, in particular to a data transmission method and device based on quantum communication. Background technique [0002] With the rapid development of communication technology, quantum communication technology has also been developed rapidly. Quantum communication technology is a communication security technology whose security has been strictly proven, and has reached the level of practicality and industrialization. Quantum secure communication is a cryptographic communication solution based on quantum key distribution. That is to use the quantum state to generate a quantum key, and use the quantum key to perform quantum encryption on the data to be transmitted before transmission. The security of quantum communication technology guarantees the security of quantum keys, thereby ensuring the security of encrypted data to be transmitted. [0003] Although the above-mentioned method ha...
