UHF RFID Information Security Transmission Technology and Application Based on Domestic Cryptographic Algorithm 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 anticounterfeiting 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 followup largescale extension of intelligent manufacturing.

An RFID Lightweight Authentication Technology Based on PUFRFID Structure Model With the rapid development of radio frequency identification (RFID) technology, RFID devices are beginning to exist widely in our daily lives, and people are paying more and more attention to RFID security. Traditional RFIDbased encryption algorithms rely on expensive Hash function. Therefore, this paper proposes a lightweight RFID authentication protocol based on Physically Unclonable Functions (PUF), which uses the machine learning algorithm and stringmatching algorithm, and presents a new mechanism of PUF challenge generation, which does not require expensive error correction code and fuzzy extractor. The implementation cost is lower. Through our security analysis, our identity authentication protocol can provide reliable security for lowcost RFID systems.
