Abstract :
Secured data broadcasting is an importantly emerging area in visible light communications (VLC). In this paper we introduce a novel approach for secured communications that is based on data beam-forming and secret channel for multiple-input-multiple-output (MIMO) VLC. Using a scrambling matrix based on either target transmission position or secret channel, it is possible to define the data-recoverable zone within the original illumination area. The paper provides theoretical development, the demonstration and evaluation of the proposed system for a MIMO VLC operating in a standard room scale.
