Towards a Lightweight Self-Sovereign Identity Framework for IoT Network in a zero trust Environment
Efat Fathalla, Youssef Azab · 2024
IoT technology is one of the most prevalent technologies today, but modern IoT security solutions are increasingly becoming obsolete. As the demand for advanced security measures grows, there is a significant emphasis on enhancing IoT security to address contemporary challenges. In order to meet these modern IoT needs, this paper introduces SSIoT, a new approach to lightweight and secure self-sovereign identity-enabled decentralized authentication for IoT devices. SSIoT integrates secret sharing schemes with blockchain technology to deliver transparent and reliable SSI-based digital identity management while minimizing storage and computational overhead. By storing IoT identity credentials externally, SSIoT protects the device’s identity credentials against tampering or misuse. The effectiveness of this model is validated through evaluations and discussions, which simulate costs and estimate verification times on actual IoT devices.
