Abstract
In the rapidly evolving landscape of communication security, this paper presents a system designed around Arduino Uno technology, specifically engineered for the secure encoding, transmission, and decoding of speech data. By integrating advanced encryption algorithms, the system ensures that speech data is transmitted in segmented bit chunks, each enveloped in multiple layers of security to prevent unauthorized access or interception. This multi-tiered encryption approach establishes a highly secure communication channel, making it nearly impossible for malicious entities to compromise the integrity of the transmitted data. Furthermore, the system’s architecture is optimized for real-time applications, ensuring both efficiency and reliability. This solution not only enhances confidentiality but also reinforces the overall security framework necessary for sensitive communication. In conclusion, the proposed system stands as a powerful integration of cryptographic security and embedded technology, making it highly suitable for applications where data protection and privacy are of paramount importance in today’s increasingly digital and interconnected world.
