Abstract
Visible light communication (VLC) can play a versatile role in future IoT (Internet of Things) - based communication services. In this paper, we first describe the latest encryption technology required to guarantee security specific to VLC and IoT to prevent eavesdropping and then the cyber-physical VLC applications of this technology.
This paper clarifies the latest communication concepts that can be implemented with the current technological level of color shift keying (CSK) communications. The CSK receiver and transmitter can identify a specific SDM frame shape, chromaticity coordinate assignment area in a color diagram, and the CSK code. After identifying both the chromaticity coordinates of CSK cells and the frame shape, the corresponding CSK cell content is paraphrased into the original data by different mapping tables. To introduce CSK communications for commercial purposes, security must be enhanced by adopting encryption technologies. It should also be noted that changing the shape of the CSK frame can significantly improve security and the error-free performance can be attained by increasing the number of CSK symbols in a frame.
We also describe new communication service concepts that can be implemented with the current technological level of CSK communication. We propose smart glasses applications using cyber-physical space by combining the VLC technology and a computer database, leading AR applications.
