With the wave of digital economy sweeping the world, 5G, artificial intelligence, big data technology, cloud computing and other emerging technologies continue to integrate with industry to accelerate the development of industrial Internet. As an important strategy of traditional industrial digital transformation, industrial Internet of Things plays an important role in today's social development. However, the data transmission security of industrial equipment in the Internet of Things has been facing severe challenges. At present, most of the industrial Internet of Things adopt centralized architecture for equipment access authentication and industrial data transmission. Coupled with the poor industrial field application environment, equipment is difficult to resist malicious attacks. Centralized authentication institutions and data transmission may cause the abuse of power of trusted institutions and the acquisition and tampering of data by third parties, resulting in data transmission security problems. In this paper, combined with blockchain technology and MQTT protocol based on TLS, a data security transmission architecture for industrial IoT is proposed to ensure the safety of equipment access and data transmission in industrial IoT.
