The intersection of IoT ecosystem security and blockchain technology in the context of industry 4.0

In this paper we have revealed and analyzed the anatomy of the intersection of Internet of Things (IoT) ecosystem security and blockchain technology in the context of Industry 4.0. The design principles and related innovative technologies to Industry 4.0 such as Industrial Internet of Things (IIoT) and edge computing have been considered. IoT and edge computing security issues have been investigated. The potential and benefits of Blockchain technology for securing IIoT are revealed such as the deployment strategies of blockchain enabled gateway and blockchain-enabled smart end devices. It has been shown that integrating blockchain with an IIoT ecosystem increases the security of the entire system.
