VLC: A Robust and Highly Secured Data Communication Service Establishment Using Visual Light enabled LiFi Technology

With the increasing demand for secure, high-speed wireless communication, Light Fidelity (LiFi) technology has emerged as a promising solution. In this paper, we propose a robust and highly secured data communication system based on Visual Light Communication (VLC) enabled by Light Fidelity (LiFi) technology. The proposed system leverages Orthogonal Frequency Division Multiplexing (OFDM) modulation, Advanced Encryption Standard (AES-256) encryption, and Low-Density Parity-Check (LDPC) error correction to enhance data transmission speed, security, and reliability. Our experimental results demonstrate that the proposed model achieves an accuracy of 97.81 %, significantly outperforming nine existing models. The system shows substantial improvements in throughput, bit error rate (BER), and latency, achieving a throughput of 148.7 Mbps, a BER of 0.018%, and a latency of 18.7 ms. The proposed model offers enhanced energy efficiency and packet loss minimization, making it suitable for high-speed and secure communication in modern environments. Our approach ensures data integrity and protection against man-in-the-middle (MITM) attacks through a machine learning-based anomaly detection system. The proposed methodology is evaluated under various conditions, and the results demonstrate that it outperforms existing LiFi models in accuracy, security, and performance
