Shavan K. Askar, Zhwan Mohammed Khalid, Tarik Ahmed Rashid · International Journal of Science and Business · 2021
Internet of Things (IoT) has grown quickly and receives considerable interest in academia and the market. However, the absence of basic technologies in protection leads to risks and security flaws in IoT privacy. IoT technologies vary from a mission-critical predicament to business-oriented applications (for example, smart grid networks, smart mobility systems, video monitoring, and eHealth) (e.g., Banking, transportation and contract law insurance) (Askar et al., 2011; Al Majeed et al, 2014). Comprehensive security support is required for IoT, particularly for task-critical applications and for business applications downstream. There have been proposals and/or utilizations of some safety methods or approaches. The platform blockchain has been suggested as an outsourced and distributed solution to guarantee protection standards and to motivate the growth of the IoT due to its decentralization and disclosure. A Blockchain is a database that store sequential manner, in multiple machine memories faulty to its opponents, any processed transactions – or records. Both participating customers share these purchases. The details shall not be stored as a public directory; each node user or device is equipped with the same directory as any other node user. In this article, present the basic blockchain structure and outline the safety criteria for developing IoT and then discuss how the IoT using's protection tools and technologies can be used via BC. Also identify the most pertinent IoT technology frameworks based on blockchain. In addition, reviewing numbers of researches provides securing IoT based on BC finally, discuss several challenges will face of IoT and BC.
