Abstract :

Of Failure, Limited Transparency, And Vulnerability To Cyber-attacks, Making Them Unsuitable For Large-scale IoT Deployments. To Address These Challenges, This Paper Proposes A Blockchain-Driven Secure Data Storage And Trusted Sharing Architecture For IoT Applications, Leveraging The Decentralized, Immutable, And Transparent Nature Of Blockchain Technology To Ensure Data Integrity And Trust Among Distributed Entities. The Framework Stores Encrypted IoT Data In Off-chain Storage While Maintaining Cryptographic Hashes And Metadata On The Blockchain To Guarantee Tamper Resistance And Verifiable Data Ownership. Smart Contracts Are Employed To Automate Authentication, Enforce Fine-grained Access Control, And Regulate Secure Data Sharing Without Reliance On Centralized Authorities. Lightweight Cryptographic Mechanisms Are Integrated To Support Resourceconstrained IoT Devices While Preserving Confidentiality. The Proposed Architecture Enhances Traceability, Accountability, And Resilience Against Unauthorized Access And Data Manipulation. Overall, The System Provides A Scalable, Secure, And Trustworthy Data Management Solution Tailored For Real-world IoT Environments. Keywords: Blockchain, Internet Of Things (IoT), Secure Data Storage, Trusted Data Sharing, Smart Contracts, Decentralized Architecture, Data Integrity, Access Control.
