What is it about?
This work introduces a chaos-based physical-layer security approach for an orthogonal frequency division multiplexing (OFDM)-based visible light communication (VLC) system with the capability against known-plaintext attacks (KPAs) and chosen-plaintext attacks (CPAs). For secret-key generation, we present chaotic key generation protocol with the help of the position-sensitive and real-valued channel state information of the VLC channel.

Why is it important?
This approach generates dynamic cyphertexts by exploiting the random characteristics of chaotic keys and input data. It performs chaotic permutation of subcarrier allocation in time/frequency domains and chaotic polarity reversal of subcarriers. The results show that our approach supports superior confidentiality for OFDM-based VLC systems against KPAs and CPAs.
Perspectives
Writing this article and getting it published is a suitable and adequate method of reporting new information about the security of visible light communication networks to the scientific community. It is also the stepping stone for the professional career of a research scientist who is interested in security.
