Lightweight ECC and Token-Based Authentication Mechanism for IoT

The Internet of Things (IoT) has modernized the latest technology by connecting multiple devices. The limited resources of IoT devices have major challenges in implementing robust security mechanisms. Conversely, cryptographic mechanisms such as RSA & DSA are more expensive, with high energy consumption and high latency values. This research proposes a lightweight authentication mechanism that combines Elliptic Curve Cryptography (ECC) with a token-based approach. The projected result ensures effective authentication, lower computational overhead, and efficient security. Our research experimental assessments determine the projected method's superiority in latency, low energy consumption, and efficient security when compared to traditional authentication methods.
