Cryptographic security for IoT : Leveraging Feistel-permutation network for enhanced encryption

The emergence of the Internet of Things (IoT) has initiated an era where numerous devices are interconnected, resulting in the generation of significant volumes of data. Data security is an issue raised by this increase in communication, especially when it comes to picture encryption. Traditional encryption methods create considerable challenges in resource-constrained IoT environments. In this paper, a novel encryption-based framework known as the Feistel-Permutation Network Hybrid is proposed. It effectively safeguards IoT image data. A comprehensive performance evaluation by utilizing MATLAB that shows the effectiveness of the algorithm used. The findings offer valuable insights into the efficacy of the algorithm. Also, the areas for further investigation within the ever-evolving field of IoT image encryption are discussed.
