Lightweight Symmetric and Asymmetric Cryptographic Protocols for Ultra-Low-Power Internet of Things Devices in Constrained Environments

Abstract

The Internet of Things (IoT) is revolutionizing industries by enabling seamless interconnectivity between ultra-low-power devices. However, ensuring security in constrained environments remains a critical challenge due to limited computational resources and energy constraints. This paper explores lightweight symmetric and asymmetric cryptographic protocols designed specifically for resource-constrained IoT devices. A comparative analysis of various existing cryptographic schemes is conducted, highlighting trade-offs between security, performance, and power consumption. Additionally, experimental results and performance evaluations provide insights into the most efficient cryptographic techniques suitable for different IoT applications.
