Abstract	Due to the broadcasting property of visible light communication (VLC) channels, VLC systems are under the threat of eavesdropping and malicious attack. In this study, the authors present an uncoordinated chaotic channel scrambling scheme to enhance the physical layer security for a multiple-input, multiple-output based VLC system. With the authors design, the legitimate receiver can self-descramble the data with the location information shared between the transceivers, and the eavesdroppers cannot retrieve the information without the secret key. The authors firstly embed the location information into the chaotic channel scrambling matrix, and then apply the non-negative orthogonal factorisation method to improve both the reliability and the security. Notably, with the aid of the shared location information, the received data can be self-descrambled and thus the uncoordinated channel scrambling could be realised. The theoretical security performances including the information leakage and the secrecy capacity are analysed and the simulation results demonstrate that the proposed scheme achieves higher security and more reliable performances compared with the counterpart schemes.
