摘要
As visible light communication (VLC) can be one of the promising wireless communication technologies in the future, improving the transmission security in VLC is highly desirable. We propose and demonstrate a secure VLC system using data superposition of different light emitting diodes (LEDs). The eavesdroppers can receive similar illumination but cannot obtain enough signal-to-noise ratio (SNR) for communication. The channel model and simulation parameters are presented. Analysis of the secure VLC zone forming using practical in-home scenarios is also discussed, showing the flexibly control the size and shift of secure VLC zone. A proof-of-concept experiment is performed, and there is a good match in trend between the experimental and simulation results. (C) 2015 Elsevier B.V. All rights reserved.
