Exploring the Synergy of Quantum Encryption and Light Fidelity for Secure Data Transmission

In the fast-paced world of digital communication, the need for secure and efficient data transmission is growing. For the growing need to integrate Quantum Key Distribution and Light Fidelity technologies to revolutionize information transfer, we propose an innovative framework that combines end-to-end quantum encryption with high-speed optical data transfer via Li-Fi, using polarized photons as bitwise data carriers. There are two components of the proposition, the hardware and the software. The hardware components facilitate the encoding, transmission, and reception of data. Software aspects involve using Arduino IDE for programming secure communication protocols, and encoding algorithms, and ensuring synchronization and the usage of Quantum Toolbox in Python for simulating the BB84 quantum algorithms and error rate analysis. Testing involves unit testing of individual components, integration testing of the complete system, and performance evaluation of Li-Fi communication speed and QKD security. The simulation converts each bit of data into a virtual photon, passing it through polarizers, and receiving it with potential bit alterations. Router R1 and Router R2 handle photon initialization, error checking, secure key establishment, and final message transmission and decryption. The integration of a Li-Fi prototype evaluates data transfer efficiency. Router R1 begins by encoding data into virtual photons and generating a secure encryption key. Router R2 receives these photons, decodes them, and verifies and decrypts the data using the secure key. The iterative process of sending, receiving, confirming, and error-checking between Router R1 and Router R2 is essential for preserving data integrity. Our results demonstrate the effective application of quantum encryption and optical data transmission, providing a scalable, secure, and efficient solution for contemporary digital communication networks.
