Özet

This work explores the secure data transmission approach to control a robotic arm using Li-Fi technology. Although Li-Fi offers built-in security by keeping the light within the walls of the environment, where it is used, leaks through windows are a concern. The proposed system addresses this concern by using a multi-mode approach with three options: without encryption, Rivest Cipher 4 (RC4) encryption, and Advanced Rivest Cipher 4 (ARC4) encryption. Users can choose the appropriate mode based on data sensitivity and processing constraints. The system transmits the movement commands to the robotic arm via a controller and transmitter. In used encryption modes, the received data is decrypted before instructing the robotic arm to perform the designated action. This secure Li-Fi system offers a promising solution for reliable and secure communication in industrial environments, addressing the limitations of traditional RF communication and improving data security.
