Audio and video transmission system based on quantum encryption

Abstract

The invention discloses an audio and video transmission system based on quantum encryption. The system comprises a first quantum key generation module, a second quantum key generation module, a quantum key transfer module, a file storage module, an audio and video extraction module, an audio encryption module, an audio decryption module, a video sampling module, a video coding module, a video decoding module, a video encryption module and a video decryption module. The method has the beneficial effects that the two quantum key generation modules are respectively used for encrypting and decrypting audios and videos, so that the high requirement of simultaneously transmitting the audios and the videos in one file by utilizing one quantum key generation module on the coding speed of the quantum key in the prior art is reduced.

Description

technical field [0001] The invention relates to the field of secure communication, in particular to an audio and video transmission system based on quantum encryption. Background technique [0002] Confidential communications refer to communications for which confidentiality measures have been taken. In addition to the use of secret codes, lingo, passwords and other security measures, modern secure communication mainly uses channel secrecy and information secrecy. Channel secrecy is the use of communication channels that make it difficult for stealers to intercept information, such as dedicated lines, instant communication and radio spread spectrum communication. Information confidentiality means that the transmitted information is concealed by means of agreed codes and ciphers before being transmitted. With the development of electronic technology, secret machines have been used to keep secrets. Its characteristic is that the transmitted information is converted and encr...

Problems solved by technology

[0004] Quantum security is also used for secure communication, but the existing quantum security communication network system is transmitting audio and video signals, and the existing audio and video are mixed in the same file for transmission. Since the audio and video are not in the same order of magnitude, the entire The file is large. When encrypting the file, the quantum key encoding speed is required to be high.
