Secure Architecture of Visible Light Communication System for Market Expansion

Progress in visible light technology has provided increased opportunities for new mobile communication infrastructures and business creation using visible light communication (VLC). This paper proposes a secure business architecture for VLC market expansion through a combination of VLC technologies, public key cryptography, power line communication, and ID management technology. The proposed architecture provides the light source of an LED with an optical location authentication ID characterized by a strict location authentication that enciphers data using public key cryptography. The network between the server for distributing the optical location authentication ID and the LED light source enables high security using power line communication. In addition, scalability can be achieved securely by means of the ID management technology. The results of an evaluation clarified the suitability of this architecture for utilization in concrete business services. Used in combination with VLC, it will contribute to the market expansion of new business related to optical electronic value trading platforms, optical digital signage, and optical Fintech.
