With the continuous development of the Internet of Things, intelligent manufacturing has gradually entered the application stage, which urgently needs to solve the problem of information transmission security. In order to realize data security with transmission encryption, the UHF RFID tag based on domestic cryptographic algorithm SM7 is proposed. By writing the anti-counterfeiting authentication identification code when the tag leaves the factory, verifying the identification code when the tag is issued, and using the authentication code of the tag to participate in the sectoral key dispersion, the purpose of data security protection is achieved. Through this scheme, the security of tag information and transmission is guaranteed, and a new idea is provided for the follow-up large-scale extension of intelligent manufacturing.
