Mohammad Qatawneh, Wesam Almobaideen, Orieb AbuAlghanam . Challenges of Blockchain Technology in Context Internet of Things: A Survey. International Journal of Computer Applications. 175, 16 ( Sep 2020), 13-20. DOI=10.5120/ijca2020920660
The Internet of Things (IoT) is a combination of communication, information, and embedded technology that truly make up an IoT ecosystem. The designing of the IoT ecosystem that includes different technologies often be complex. This complexity introduces challenges to keeping the IoT secure, protecting the IoT from disclosure to unauthorized parties, ensuring information integrity and so on. This paper presents a comprehensive survey of the challenges and security consideration of the integration of both IoT architectures and blockchain technology which is basically a secure distributed database over a peer to peer architecture. It starts by discussing the characteristics of the IoT, its architectures, their limitations and the role of cloud and fog computing to overcome these limitations. Then it provides an overview of a blockchain technology, its applications, how does it work, and finally the contribution of an integrated blockchain as a solution to security and privacy challenges in IoT.
