Blockchain-Based Security Models for Industrial IoT Networks

Abstract

IoT networks have revx`xolutionized operations of manufacturing and industry through a seamless connection, real-time, and intelligent automation. However, these networks are extremely susceptible to security attacks, because there are numerous associated devices, a variety of protocols and significance of industrial processes. Some of the threats that are too difficult to be handled in the traditional centralized security systems are data manipulation, unauthorized access and denial of service attacks. The blockchain technology has been brought up as one of the possible solutions to make IIoT networks secure since it is decentralized, immutable, and transparent. The security models of blockchain about IIoT applications are discussed in this paper with the specific issue of authentication, data integrity, access control and secure data sharing The methodology will be based on a comparative analysis of the available blockchain frameworks, and experimental simulations and testing their functionality on the basis of the latency, throughput and scalability. These results demonstrate that the introduction of blockchain to IIoT networks has the positive impact on the introduction of higher levels of security, the reduction of single points of failure, and the establishment of untrusted interactions among industrial computers as well as the problems of resource scarcity and network congestion. The findings can be employed in offering feasible information on the way of building secure, efficient, and scalable IIoT systems.
