Blockchain-Driven Zero Trust Framework for Enhancing Network Security in Distributed Enterprises

This paper introduces a blockchain-based method for IoT programs to transfer data securely. As the number of Internet of Things (IoT) devices rises and the demand for safe and immutable data management grows, traditional centralized systems have single points of failure and flaws that allow unauthorized access. The suggested solution protects data during transmission and storage using cryptographic encryption, hashing, consensus mechanisms, and smart contracts. Blockchain-based solutions are decentralized, so data cannot be changed, and encryption and hashing safeguard it. The consensus mechanism verifies transactions and ensures nodes are in sync, making the network secure. Smart contracts allow fine-grained access control, limiting sensitive data to authorized devices and persons. The proposed solution outperforms current systems in privacy, data integrity, security, scalability, and energy economy. The suggested method works well with big IoT networks, requires little energy, and has minimal latency, making it useful for many IoT uses. This study shows how blockchain technology may provide a safe, effective, and scalable IoT data management system. This approach would prepare future IoT ecosystems to securely communicate data.
