High-speed VLC Security System Using Two Key Services by Multi-point Analysis

Visible Light Communication (VLC) is a new and unregistered technology under the IEEE 802.15.7 standard. The light-emitting diode (LED) is used in the majority of applications. Despite the fact that all applications have a secure data flow, only fixed vital management methods are used and attackers may be able to hack or disintegrate those keys. With the logistic and Henon algorithms, the proposed novel mapping method provides excellent security (HLM). In this approach for generating crucial sequences, random number generation (RNG) is used. The chaotic system of the non-linear dynamic discrete-time source is used to extract the HLM cryptography source. In this proposed work, the novel design of critical generation, utilizing HLM-RNG, is mathematically evaluated and simulated in MATLAB, to produce a crypto key-based security system that employs two diffusion and permutation processes as cropping techniques. This proposed system obtains quick encryption of 0.16 s through test analysis, sensitivity analysis, statistics utilizing histogram analysis, correlation of 0.0001 difference analysis and information entropy of 7.99. It can also keep the bit error rate (BER) at 0.993e−6, according to the BER study.
