The Internet of Things (IoT) is rapidly expanding, but its security and privacy challenges remain significant. Traditional encryption methods struggle to balance data confidentiality with computational efficiency, especially in resource-constrained IoT environments. Blockchain technology offers decentralized security, but its integration with IoT faces scalability and privacy limitations. This paper proposes a security-enhanced blockchain-oriented IoT communication protocol utilizing homomorphic encryption (HE) to enable encrypted data processing without decryption. The proposed framework ensures data integrity and privacy while maintaining computational feasibility. The study evaluates the performance of various HE schemes, blockchain consensus mechanisms, and cryptographic protocols in IoT networks. Simulation results indicate that the proposed approach enhances security, reduces computational overhead, and maintains low latency in IoT communications.
