Abstract

The invention provides a quantum encryption-based video communication system. The system comprises multiple video meeting modules and a meeting general control module. Each video meeting module at least comprises a video meeting terminal and a corresponding quantum key machine. The meeting general control module comprises a meeting control terminal and a corresponding general control quantum key machine. The general control quantum key machine and the quantum key machines at least access a quantum network. The general control quantum key machine and all the quantum key machines at least prestore network addresses and network accounts of all the quantum key machines and the general control quantum key machine. A point-to-point key pair comprising a first key and a second key grows between the general control quantum key machine and the quantum key machine of each video meeting module. A QKD technology and video communication are combined effectively, so that multi-party encrypted video communication is realized.

Description

technical field

[0001] The present invention relates to video communication technology, in particular to a video communication system and method based on quantum encryption. Background technique

[0002] Video communication is more and more integrated into daily life and work, which brings many conveniences but also brings security risks, and there is a possibility that video communication may be illegally intercepted. In order to ensure the security of video communication, video information needs to be encrypted. Encryption involves two parts, the encryption algorithm and the key. With the popularization of computer technology, the encryption algorithm tends to be highly complex and has high security. However, the generation and transmission of the key are easy to be cracked, resulting in information leakage.

[0003] With the combination of quantum physics and information technology, Quantum Key Distribution (Quantum Key Distribution, QKD) technology has become a hope to ...
