Design and Performance Analysis of Lightweight ECC-Based Authentication Protocol for Low-Power IoT Applications
Neha Purohit, Shubhalaxmi S. Joshi · 2025
As the Internet of Things (IoT) grows quickly, it's important to make sure that security measures are strong but not overly intrusive, especially in places with limited resources. Elliptic Curve Cryptography (ECC) has become popular because it has strong security and small key sizes that make it perfect for IoT apps that need to use little power. The main goal is to provide strong protection with as little energy use and computing complexity as possible. The suggested protocol includes a customizable ECC system that works best with IoT devices and uses curves like SECP256R, SECP384R, SECP521R, SECT283K, and BrainpoolP512R. Performance assessment focuses on critical parameters including computational cost, memory utilization, energy consumption, authentication latency, and communication overhead. Experiments show that the suggested ECC-based identification makes system processes much easier and saves a lot of energy, showing that it can be used in real-world low-power IoT deployments. The results of the study are very helpful for creating ECC identification methods for IoT settings that are safe, scalable, and energy-efficient. This improvement successfully fixes the speed and security issues with current IoT identification methods, making them more widely used and providing better security for many IoT apps.
