LIGHTWEIGHT SECURE ARCTITECTURE TO VALIDATE DATA AUTHENTICITY IN IOT - ENABLED DEVICE

Abstract

Ensuring the authenticity and integrity of the data provided by Internet of Things (IoT) devices is essential as they multiply in critical applications. This study proposes a lightweight secure architecture to validate data authenticity in resource-constrained IoT contexts. The system includes cryptographic primitives, trust-scoring techniques, and a decentralized verification protocol. The architecture uses elliptic curve cryptography (ECC) and hash-based message authentication codes (HMAC) to ensure low computing overhead. Tests demonstrate that the proposed architecture maintains scalability and energy efficiency across a range of IoT devices while offering robust protection against data tampering and spoofing threats.
