Abstract

Underwater communication is hampered by electromagnetic wave attenuation and scattering. Light Fidelity (LiFi) resolves this issue by providing secure optical data transmission with enhanced confidentiality and integrity. The setup consists of a LiFi transmitter, receiver, and an encryption/decryption Python script. Data is encrypted with XChaCha20-Poly1305 and transmitted through CP210 (USB-to-UART) to the LiFi transmitter, which modulates the data into optical signals for underwater transmission. The receiver receives, decodes, and transmits data back to the PC through CP210 (UART-to-USB), where it is decrypted. PBKDF2 makes it secure by allowing only authenticated users with the correct password to decrypt the data. This configuration offers a safe, efficient, and real-time underwater communication system for uses such as marine research, military, and robotics.
