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 invention belongs to the fields of visible light communication and quantum communication, and in particular relates to a quantum encryption system for visible light communication. Background technique [0002] Visible light communication technology is a technology that uses lighting devices such as light-emitting diodes to communicate. It is mainly based on high-frequency visible light signals emitted by high-frequency lighting devices to transmit information. It is easy to use and has a large communication volume. Traditional radio signal transmission equipment has many limitations. They are rare, expensive, and inefficient. For example, mobile phones. Millions of base stations around the world help them strengthen the signal, but most of the energy is spent on cooling, which is very inefficient. In contrast, the light bulbs used all over the world are inexhaustible, especially white LED light sources are replacing traditional incandescent lamps o...
