Private information security sharing method of industrial Internet of Things based on blockchain technology
In the application scenarios of the industrial Internet of Things,the conventional privacy information security shar-ing method relies on the centralized data verification,storage and sharing mechanism,which has a single point of failure risk.Once the central server is attacked by the network,the system will face a large number of disordered request challenges,the sharing mechanism will become unstable,and then cause the sharing jitter,seriously threatening the security of privacy information.To this end,a method of sharing industrial privacy information based on blockchain technology is proposed.Deployment information collec-tion nodes first according to current determination requirements and standards.The blockchain technology is used to set up mul-tiple target area blocks,and the data collected by nodes is multi-target above-ground chain,so as to increase the fault tolerance of the chain on the data,and reduce the impact of a single point of failure.On the basis of realizing the multi-objective upper chain,a sharing request mechanism is established to process the sharing requests in an orderly and controllable way,so as to reduce the sys-tem jitter caused by the disordered requests.In order to further guarantee the security of privacy information,a decentralized data sharing model is built by using the characteristics of decentralization and data imtamability of blockchain.In this model,strict ac-cess rights and shared tracking function are enabled,which can detect and handle potential security risks in time and ensure the se-curity and controllability of data sharing.The test results show that the proposed method is applied to share the privacy information of the Internet of Things,and the jitter value is less than 2.5 ms,which is better than the comparison method,and the application ef-fect is better.
