The rapid proliferation of Internet of Things (IoT) devices has heightened concerns regarding device authentication and data integrity within IoT ecosystems. Traditional centralized security mechanisms often fall short in addressing these challenges due to scalability and trust issues. This paper proposes a decentralized blockchain-based framework to enhance device authentication and ensure data integrity in IoT networks. Leveraging blockchain's immutable ledger and consensus mechanisms, the framework provides secure and transparent device registration, authentication processes, and tamper-proof data storage. The integration of homomorphic encryption further bolsters data privacy by enabling secure data processing. Through simulation and analysis, the proposed framework demonstrates improved security, scalability, and efficiency, offering a robust solution to the pressing security concerns in IoT environments
