Blockchain-Based Framework for Secure IoT Data Transmission

In response to the growing demand for security in IoT networks. Technology that is decentralized is used in this architecture. The suggested architecture includes blockchain oracles to securely connect blockchain with off-chain Internet of Things data. By using decentralized and secure Internet of Things oracles, this guarantees verifiable and trustworthy real-time data flow. Furthermore, artificial intelligence-powered Internet of Things security procedures are used to monitor and defend Internet of Things devices against emerging cyber threats. These techniques include threat intelligence solutions supported by blockchain technology and anomaly detection powered by AI. The IOTA Tangle architecture is utilized by the framework. This architecture provides scalable and fee-free data transfers, making it ideal for Internet of Things ecosystems. Strong, secure, and effective communication between Internet of Things devices is ensured by this method. Increased data integrity, privacy, and real-time threat detection from multiple devices are also made possible by it. This study presents a potential solution to the security issues that contemporary IoT systems are now facing, as well as an examination of the practical implementation of these technologies in protecting data transmission over the Internet of Things (IoT).
