Identity authentication is one of the methods to protect the security of devices in the Internet of Things. In view of the security and privacy protection problems caused by identity authentication in traditional centralized platforms, this paper combines the blockchain technology with the existing authentication model of the Internet of Things. Firstly, the authentication strategy is formulated according to the attributes of the IoT device; secondly, the use of cryptography technology to ensure transmission security, so as to ensure the data transmission security, reliability and authenticity of the Internet of Things, and realize the transmission security, network security and data security of The Internet of Things devices; finally, the model anti-attack ability is tested and analyzed from the aspects of performance and security.
