BLOCKCHAIN-BASED SECURE FRAMEWORK FOR IOT DEVICES

Abstract [English]

The Internet of Things (IoT) has revolutionized industries by enabling the interconnection of devices, creating opportunities for enhanced automation and real-time data analysis. However, the rapid proliferation of IoT devices has introduced significant security vulnerabilities, such as unauthorized access, data manipulation, and privacy breaches. These challenges stem from the inherent limitations of IoT devices, such as low computational power, and the reliance on centralized security models that are susceptible to single points of failure. To address these issues, this paper proposes a Blockchain-Based Secure Framework for IoT devices. Blockchain, a decentralized, immutable, and transparent distributed ledger technology, offers an effective solution for securing IoT networks. By leveraging blockchain's cryptographic features and consensus mechanisms, this framework ensures secure device authentication, data integrity, and transparent communication between IoT devices. Devices can securely authenticate themselves through blockchain-based digital identities, eliminating the need for centralized servers, thus reducing the risk of unauthorized access.
Moreover, the framework guarantees data integrity by recording all IoT transactions on the blockchain, making them tamper-proof and verifiable. Blockchain's decentralized nature also mitigates the risk of Distributed Denial of Service (DDoS) attacks by removing central points of vulnerability. Privacy is enhanced through techniques such as zero-knowledge proofs, allowing users to control access to their personal data. This proposed framework not only enhances IoT security but also provides scalability, transparency, and resilience. By combining the strengths of blockchain with IoT, it offers a robust solution for secure, reliable, and privacy-preserving communication in the ever-growing IoT ecosystem. The integration of blockchain technology is poised to transform IoT security, facilitating the secure deployment and management of IoT devices across various industries.
