Research on Collaborative Sharing of IoT Data Information Based on Blockchain Technology
In the process of connecting intelligent network devices to the cloud in the Internet of Things environment,a large amount of user access data,intelligent terminal control service data,cross domain shared data and other information will be generated.It is also inevitable to bring security risks to the access,transmission,storage and sharing of Internet of Things data information,including a series of problems such as diverse data storage formats,chaotic traceability and access control,cross domain data leakage and uncontrollable data sharing.Therefore,a cross domain data security sharing model for the Internet of Things is proposed based on data encryption technology,distributed storage technology,MQTT transmission protocol,composite account control management mechanism and other technologies.Attribute-based encryption algorithms are used to overlay digital signature information of multiple network nodes and perform bilinear pairing data encryption/decryption operations.Intelligent contracts are used to share and manage data information on the network chain,and improve the security of cross domain access,transmission and sharing of encrypted data in the Internet of Things.
