Enhancing IoT Device Security Through Digital Twins and Lightweight Cryptography: A DittoTinyJAMBU Approach

Abstract

The proliferation of Internet of Things (IoT) devices has brought about significant advancements in various sectors, including healthcare, manufacturing, and smart cities. However, the security of these devices remains a critical concern. This paper presents a novel approach to enhancing IoT device security by integrating Digital Twins (DTs) with lightweight cryptography, specifically the TinyJAMBU algorithm. The study explores the architecture and implementation of this approach using the Eclipse Ditto framework and MQTT protocol. The results demonstrate the effectiveness of the proposed solution in ensuring data confidentiality, integrity, and authentication while maintaining low computational overhead suitable for resourceconstrained IoT devices. This research contributes to the field by providing a scalable and efficient security solution for IoT ecosystems.
