The Role of Blockchain Security in the Internet of Things

Abstract

Blockchain may be a new technology within the Internet of Things (IoT). It functions with the public, distributed, decentralized, and instantaneous ledger to stockpile various transactions within the nodes of IoT. A Blockchain comprises of sequences of blocks with each component linked to the previous block sequences. Individual blocks contain previous block hash, cryptography hash code, and stored sets of knowledge. The transactions, which happen within the Blockchain are the elemental elements, which transfer data from one IoT node to a different one. The nodes vary in physical composition, though all of them have actuators, sensors, and programs; thus, they will communicate with one another. The function of Blockchain in IoT is to ensure a secure process of transferring data through the nodes. The technology is efficient and usable publicly without worrying about knowledge pilferage. The blockchain is important for IoT because it enables the secure transfer of data between its nodes in an environment, which is heterogeneous. The communications in blockchain are traceable to a person who has the permission to exchange information within the IoT. The system may help in IoT to reinforce the safety of communication data. This paper, reconnoitered the weakness of IoT security, the importance of Blockchain technology in IoT, the integration of blockchain in IoT, and therefore the design architecture of the integrating of IoT and Blockchain.
