Research on trusted storage model of IoT sensor data based on blockchain
IoT sensors collect,store,and process massive amounts of data,which are directly related to the data security of the country,society,enterprises,and people.On the basis of the study of blockchain technology,IPFS and cryptography technology,us-ing the characteristics of blockchain,such as traceability,collective maintenance and non-tampering,combined with the distributed storage and non-tampering characteristics of IPFS,and using attribute-based encryption,proxy re-encryption and ciphertext search-able technology,a trusted storage model of IoT sensors data based on blockchain technology is proposed,a decentralized zero-trust storage environment is constructed,and the trusted storage and secure sharing of IoT sensor data are realized.It has great applica-tion value for improving the security of IoT sensor data.
