AN OVERVIEW OF SECURED COMMUNICATION THROUGH IOT NETWORK USING BLOCKCHAIN

Internet of Things (IoT) research and industrial growth is accelerating, yet it still has privacy and security issues. Due to the decentralised architecture and resource constraints of the majority of IoT components, conventional security and privacy solutions are typically inapplicable to IoT. Each block in a blockchain is connected to the one that came before it. Every block contains the cryptographic hash code, the hash of the previous block, and the block's data. BC transactions are the primary data transfer units used between IoT nodes. IoT nodes are intelligent physical objects having embedded sensors, actuators, and programming that can communicate with other IoT nodes. The function of BC in the IoT is to provide a method for processing encrypted data records via IoT nodes. BC is a technique that can be utilised publicly and safely. This type of technology is required by IoT in order to ensure secure communication between IoT nodes in a complex environment. In this article, communication via Blockchain technology adoption in an IoT network is regarded as safe and secure.
