Abstract:

Improved security against cyber-attacks, eavesdropping, and interference threats is necessary to establish 6G networks. With its inherent spatial confinement and high-rate data transmission, Visible Light Communication (VLC) can substitute conventional radio frequency (RF)-based security techniques challenged by spectrum congestion and jamming attacks. Constraints such as eavesdropping threats, low flexibility to mobility constraints, and time-varying environmental interference are issues that face VLC security solutions. Adaptive Quantum-Secured Visible Light Communication (AQ-SVLC) has been proposed to mitigate these issues. The paradigm combines Quantum Key Distribution (QKD), artificial intelligence-based adaptive beamforming, real-time channel state monitoring, and blockchain-based authentication with the aim of enhancing trustworthiness, flexibility, and confidentiality. The AQ-SVLC design guarantees real-time security adaptation by dynamically adjusting transmission parameters using Deep Reinforcement Learning (DRL) models. A hybrid optical-RF switching mechanism allows flawless connectivity even when the lighting changes. In 6G networks, the results show that AQ-SVLC provides a future-proof and scalable solution for strong physical layer security, far better than traditional VLC security techniques. For the purpose of guaranteeing that next-generation wireless communication ecosystems have security that is both adaptive and supported by AI, this research presents AQ-SVLC as a revolutionary method. While reducing bit error rate (10.8%) and latency (32.8 ms), the suggested AQ-SVLC method outperforms current security solutions in secrecy (97.3%), robustness (99.8%), and efficiency (98.3%).
