Visible light communication (VLC) technology has emerged as a significant and necessary improvement to the wireless communication technologies; VLC systems are considered to be more secure than wireless fidelity (Wi-Fi) systems by design, since light cannot penetrate most walls and obstacles. This paper presents a design for a bidirectional VLC system, and it also introduces a method to jeopardize the security aspect of this system. The methodology in this paper is side-channel attack which is defined as exploiting data based on the information gained from physical implementation. It is not a cyber attack on the theoretical weaknesses in the algorithms, but rather is a sideway approach to a fully-functioning physical system. Thus, the authors became the attackers and implemented a current sensor on the power lines from the power supply to the VLC system; the instantaneous power consumed by the communication system has become their main source to obtain the binary data transmitted by visible light. The work has resulted in effective attacks which could successfully extract the information and it has demonstrated side channel attacks on VLC systems through their instantaneous power consumption analysis.
