Abstract: This paper analyzes the standard authentication mechanism of EPC-C1G2 protocol and existing improved schemes. A lightweight RFID authentication scheme is proposed according to the security problem of existing UHF RFID authentication schemes. The mutual authentication between reader and tag can be achieved in the scheme, and the lightweight encryption algorithm of the scheme can guarantee that the transmission of messages is secure. Analysis results show that the scheme has good security performance and can meet the security requirements of UHF RFID.
