摘要：

Blockchain has the advantages such as decentralization and data immutability, its application in data security is very extensive. However, the fieldbus system that connected physical layer equipment had limited computing resources and poor communication capabilities in an industrial control system. It was difficult to deploy the block-chain on an industrial control system. For this reason, a lightweight private blockchain scheme was proposed to protect the data integrity at the fieldbus level. A random verification mechanism was designed, in which a part of nodes are randomly selected to participate in the consensus process. This mechanism not only saved communication cost, but also enhanced the security of the scheme. A new consensus model was proposed, which could adopt different consensus strategies according to the states of the consensus nodes to reduce the calculation and communication burden of the nodes. Security analysis proved that the proposed scheme had certain probability to against the 51% attack except for common data integrity attacks. Compared with existing schemes, simulation showed that the proposed scheme had significant advantages in terms of security performance, time and communication cost. © 2022 CIMS. All rights reserved.
