Abstract

The invention relates to a voice signal quantum encryption communication system based on a random number, which comprises terminal equipment, a quantum communication access point, a quantum communication gateway and a quantum communication access point, wherein the terminal equipment consists of a terminal sending subsystem and a terminal receiving subsystem; the terminal sending subsystem comprises a quantum key agreement and management module, a voice signal encoding module, a random number generation module, a voice encryption module and a digital modulation module; and the terminal receiving subsystem comprises a voice signal decoding module, a quantum key agreement and management module, a voice decryption module and a digital demodulation module. One piece of terminal equipment simultaneously comprises the terminal sending subsystem and the terminal receiving subsystem. According to the invention, the terminal sending subsystem is applied to send a voice signal with good encryption performance and high anti-interference performance and meanwhile, the terminal receiving subsystem is utilized to receive and reduce the voice signal, so that safety and integrity in the communication process are ensured.

Description

technical field [0001] The invention discloses a voice signal quantum encryption communication system based on random numbers, belonging to the fields of voice signal processing and signal encryption. Background technique [0002] Since the invention of the telephone, modern voice communication technology has been widely used in the fields of economy, society, national defense, and scientific research, including wired voice communication and wireless voice communication, which have greatly improved the national economy, production and life, national defense and military. communication efficiency.
