SUSTAINABLE IOT PROTECTION AND IMPROVEMENT UNDER ACT OF 2020: A SMART BLOCKCHAIN-BASED FRAMEWORK TO MITIGATE DISTRIBUTED DENIAL OF SERVICE ATTACKS

Abstract

The speedy growth of Internet of Things (IoT) networks across metropolitan and domestic situations has increased vulnerability to Distributed Denial of Service (DDoS) attacks, which overcome systems with extreme traffic and interrupt legitimate services. This research introduces BlockSecure, a peer-to-peer ledger–based defensive mechanism particularly intended to improve IoT flexibility against DDoS threats. The structure leverages blockchain’s decentralization and immutability to eradicate single points of stoppage and set up trust across unified devices. The methodology commence with network initialization, including device recognition and protected communication setup, followed by the assortment of appropriate ledger architecture (public, private, or consortium). Smart contracts are employed to manage device verification, data-sharing rules, and secure communication protocols. Cryptographic keys ensure trusted communications, while real-time traffic observes enable early finding of strange activities. Upon identifying a possible attack, BlockSecure autonomously mitigates risks by blocking malicious sources or rerouting traffic to preserve service stability. All incidents are enduringly recorded on the distributed ledger, produce a reliable knowledge base for ongoing modification of security plans. Through adaptive learning and continuous updates, BlockSecure demonstrates a dynamic, scalable, and sustainable approach to protecting IoT infrastructures from persistent DDoS threats, thereby ensuring long-term network integrity and availability.
