A security enhanced tag developed by Fudan University is introduced in this paper. This tag is designed to be compatible with EPC Class 1 Generation 2 protocol (EPC C1G2), and can be extended to support mutual authentication and to encrypt communication between reader and tag. A mutual authentication scheme is proposed, and low cost cryptographic algorithm core is implemented in the tag to accomplish authentication and encrypted data exchange, in order to resist the tracing attack and common attacks. A whole tag chip, including RF/analog front end, digital core and EEPROM, has been taped out on SMIC 0.18 micrometer process.
