Enhancing Iot Security: Integrating Blockchain with Smart Contracts for a Robust Software Engineering Framework

Abstract

The Internet of Things (IoT) has revolutionized how devices interact and communicate across various sectors, from healthcare to industrial automation. However, this rapid expansion has introduced significant security challenges, making the need for a robust security framework more urgent than ever. This paper proposes a novel software engineering framework that integrates blockchain technology and smart contracts to enhance IoT security. The framework addresses critical challenges such as data integrity, privacy, and scalability by leveraging the decentralized nature of blockchain and the automation capabilities of smart contracts. The architecture is structured into three primary layers—IoT Device Layer, Blockchain Layer, and Application Layer—each playing a crucial role in securing the IoT ecosystem. The inclusion of a comprehensive Security Layer ensures encryption and privacy across all stages of data handling. This framework's effectiveness is validated through real-world IoT applications, demonstrating its scalability and adaptability across various industries. This paper contributes to the advancement of secure IoT deployments by offering a resilient, scalable, and efficient security framework.
