An Intelligent Blockchain Framework for Secure Communication in IOT Environments

IOT (Internet of Things) is rapidly expanding with the creation of smart environments around agriculture, healthcare, industrial automation and transportation. However, as the number of sensitive data exchanges between different IoT devices increases, the number of privacy and security challenges is also growing. These challenges include unauthorized access to, or tampering of, data; identity spoofing; and cyberattacks. Most traditional security models are centralized and are either too slow due to their inherent scalability limitations or possess a single point of failure which makes them unsuitable for IoT ecosystems of a large-scale and dynamic nature. This intelligent framework will allow for decentralized blockchain architectures coupled with intelligent security mechanisms to provide for secure, transparent, and tamper-proof communications between devices on the Internet of Things as well as those on IoT networks. The framework will use ledger-like technology, smart contracts, lightweight encryption techniques, and intelligent authentication to increase the integrity of data, preserve the privacy of that data, and create trust management options among all devices connected by their respective IoT networks. Edge-enabled blockchain processing will also be included within the framework to reduce the computational overhead in processing transactions and to increase the efficiency of real-time communications. The experimental analysis of the intelligent blockchain framework will demonstrate how it can substantially improve security for communication over other forms of conventional IoT security models and reduce risk of unauthorized access to information, increase reliability in the transaction process, and decrease vulnerabilities to each network compared to other traditional models of security in the Internet of Things.
