Increasing Physical Layer Security through Hyperchaos in VLC Systems. (arXiv:2212.08927v1 [cs.CR])

Visible Light Communication (VLC) systems have relatively higher security
compared with traditional Radio Frequency (RF) channels due to line-of-sight
(LOS) propagation. However, they still are susceptible to eavesdropping. The
proposed solution of the papers have been built on existing work on
hyperchaos-based security measure to increase physical layer security from
eavesdroppers. A fourth-order Henon map is used to scramble the constellation
diagrams of the transmitted signals. The scramblers change the constellation
symbol of the system using a key. That key …
