Enhancement of Security in IoT Using Modified AES Algorithm for IoT Applications

The proliferation of Internet of Things (IoT) devices has led to a surge in data exchange over networks, making security paramount for ensuring the integrity and confidentiality of transmitted information. This paper proposes a novel approach for bolstering security in IoT environments by employing a modified Advanced Encryption Standard (AES) algorithm tailored to suit the unique requirements of IoT applications. The conventional AES algorithm, while highly robust, poses challenges in terms of computational resources and energy consumption when implemented on resource-constrained IoT devices. To address these limitations, our proposed modification leverages lightweight cryptographic techniques, optimizing the algorithm for low-power microcontrollers commonly found in IoT devices. The modified AES algorithm exhibits a significant reduction in computational accuracy while maintaining a high level of security. By adapting modified AES to the IoT ecosystem, the study aims to mitigate potential vulnerabilities and improve the overall security of IoT networks. To validate the efficacy of the proposed approach, extensive simulations and experimental studies were conducted on a diverse set of IoT devices across varying network conditions. The results demonstrate a substantial improvement in security performance metrics including throughput, latency, and energy consumption compared to conventional methods.
