The real-name registration management of the Internet of Things (IoT) card is of great significance to the security development of the Internet of Things and the security construction of Cyberspace. However, IoT cards are decoupled from people in the circulation process, are often "re-sold", data sharing is difficult in cross-departmental circulation, and data quality is low. But the IoT card is the key for things to connect to the Cyberspace. The traceable management of the IoT card can ensure the identity analysis of Machines, Things, and People in the Cyberspace. This paper gives us a solution based on blockchain and secure terminals. With this solution, we can promote the data on the chain of each transaction chain effectively, improves the accuracy and effectiveness of the collected information, realizes the joint participation and system co-governance of different responsible entities, and improves the IoT card Real-name registration rate, the management ability to the network, etc. Experiments have fully proved the effectiveness, reliability, and advancement of the system, which has a massive role in accelerating the improvement of the comprehensive level of network security technology and helping the construction of a cyberspace integrity system.
