Abstract

The invention discloses a quantum encryption system for visible light communication. The system comprises a communication gateway and a communication terminal. The communication gateway comprises a first quantum key allocation module and a first visible light communication module. The communication terminal comprises a second quantum key allocation module and a second visible light communication module. The first quantum key allocation module comprises a first photon generator, a QKD system and a first encryption and decryption system. The first visible light communication module comprises a first modulator-demodulator, a first LED light source and a first optical signal receiver. The second quantum key allocation module comprises a second quantum key analyzer and a second encryption and decryption system. The second visible light communication module comprises a second modulator-demodulator, a second optical signal receiver and a second LED light source. Two communication parties carry out encryption and decryption processing on visible light transmission information through utilization of a quantum encryption and decryption system. Further, quantum identity authentication and quantum message authentication can be carried out on the visible light communication, so the visible light communication has theoretically absolute security.

Description

Technical field [0001] The present invention belongs to the field of visible optical communications and quantum communication, and is specifically a quantum encryption system for visible light communication. Background technique [0002] The visible optical communication technology is a technique for communicating using lighting devices such as light-emitting diodes. It is mainly based on high-frequency visible optical signals emitted by high frequency lighting devices to transmit information, easy to use, and large traffic. There are many limitations of traditional radio signal transmission devices, which are rare, expensive, high efficiency, such as mobile phones, millions of base stations around the world to help them enhance signals, but most of the energy is consumed in cooling, and the efficiency is very low. In contrast, the light bulb used worldwide is not exhausted, especially white LED light sources that replace traditional incandescent lamps in large-scale, which is a ...
