Blockchain meets IIoT: An architecture for privacy preservation and security in IIoT

Industry 4.0 articulates that modern intelligent machines are better than humans that are enough capable to capture and analyze data in real-time, as well as in communicating information that may be helpful to take business-related decisions faster. The Industrial Internet of Things (IIoT) relies on intelligent assets that communicate and store data, data communication infrastructures, analytics, and people for functioning. With so many constituents of the IIoT network, there is also an increased potential for security risks. Privacy and trust issues need to be addressed. Recently Blockchain Technology has shown tremendous growth due to its reliable nature. In this paper we introduce a blockchain technology-based architecture for IIoT with the aim to address a lot of significant security issues
