In the rapidly developing industrial ecosystem,the usage and demand of data in the Industrial Internet of Things is increasing,and maintaining the integrity and security of data has become an important responsibility and requirement.Data integrity refers to the accuracy,reliability and consistency of data throughout its life cycle.Data security refers to protecting data from unauthorized access,modification,deletion and theft.This paper enhances the integrity and security of industrial Internet of Things data by referring to blockchain technology.Starting from the data collection of industrial Internet of Things sensor devices,it is transmitted to the private blockchain gateway,the data is decrypted by the zero-knowledge proof method,and a new storage location is introduced to update the blockchain.The data is verified and authenticated through a consensus mechanism to ensure the integrity and security of the data recorded on the blockchain.
