IOTGUARD: A LIGHTWEIGHT AND ENERGY-EFFICIENT ENCRYPTION ALGORITHM FOR SECURE DATA TRANSMISSION IN IOT NETWORKS

Abstract

The rapid growth of the Internet of Things (IoT) has amplified security challenges, particularly for resource-constrained devices that struggle to implement traditional encryption methods due to their limited computational and energy capacities. This study introduces IoTGuard, a lightweight and energy-efficient encryption algorithm specifically designed for secure data transmission in IoT networks. IoTGuard integrates hybrid cryptographic techniques to balance performance and security, ensuring minimal resource consumption. Comparative evaluations with existing cryptographic algorithms such as AES, ChaCha20, and RSA reveal IoT Guard's superior efficiency in terms of encryption/decryption speed, energy consumption, and compatibility with constrained environments. The findings underscore IoT Guard's potential to address pressing security needs while preserving the operational viability of IoT systems.
