Blockchain Applications for Security Issues and Challenges in IOT

A common network image (COP) across the numerous applications of contemporary life was made possible by the internet with things (IoT). The development of wireless sensor network devices, which allowed data to be exchanged and numerous analyses to be carried out, allowed for the achievement of the COP. IoT raises security and privacy issues since data authentication and exchange are handled only via the central server. There might be a possibility of device spoofing, incorrect authentication, and decreased data exchange dependability. A central server’s model is dropped and cryptocurrency (BC) technology is added as a component of IoT to solve similar confidentiality and security problems. This study examines how the distributed ledgers based on block chain (DL-BC) technology contributes to potential security and privacy concerns in the context of IoT component interaction. Application of BC with regard to the targeted industries and categories were obviously examined here. To comprehend the role of blockchain technology, certain issues unique to IoT and IoT using BC also were explored.
