A Blockchain-Based Trusted Upload Scheme for the Internet of Things Nodes

In recent years, the theory and method of swarm intelligence based on the Internet have become the core research field of the new generation of Internet of Things (IoT). Both play a basic and supporting role in other research fields of IoT. With the popularization and development of crowd network systems, massive swarm intelligence data have brought unprecedented challenges to traditional centralized data management. The most prominent is the aspect of privacy and security. In view of the fact that source data are easy to be tampered with and stolen, and there is a lack of credit guarantee mechanism in information sharing, a blockchain-based trusted uploading scheme of IoT nodes is proposed. It carries out trusted design from three dimensions of node hardware, transmission link, and platform and provides relevant references for similar designs.
