Abstract

In order to solve the problem that data of the industrial Internet of Things (IIoT) is easily tampered with and therefore, the authenticity of data may be questioned, a data-privacy security mechanism of the IIoT based on blockchain is proposed. At the same time, to solve the problem of master node selection and low efficiency in the practical Byzantine fault tolerance (PBFT) algorithm, a reward mechanism based on node behavior is introduced and an improved PBFT algorithm is proposed. The improved PBFT algorithm is more efficient, in line with the application scenarios of the IIoT. Comparative analysis results showed that the proposed blockchain-based data-privacy security mechanism of the IIoT is superior to other models in terms of consensus efficiency, throughput, and block generation speed.
