Visible Light Communication (VLC) is a wireless technology that exploits Light Emitting Diodes (LEDs) for both, illumination and data communication. A major challenge is that this system is vulnerable to passive attacks due to the broadcast nature of wireless networks. In this paper, an efficient and lightweight cipher scheme for VLC systems is proposed at the physical layer. Unlike previous schemes in the literature, the proposed one-round scheme utilizes simple substitution and phase shuffling operations to secure the underlying Orthogonal Frequency Division Multiplexing (OFDM) symbols. A dynamic key derivation scheme that benefits from the dynamic properties of VLC channels is also proposed. Experimental simulations and cryptanalysis show that the proposed solution strikes a good balance between performance and security robustness.
