Distance-Bounding Protocol with Time-Stamped Authentication for RFID

Relay attack is one of the most challenging threats that RFID will have to face now. Distance bounding protocols form a family of challenge-response authentication protocols and confirm the round-trip time at the Rapid Bit Exchange phase that have been introduced to thwart relay attacks. They enable a reader to authenticate and to establish an upper bound on the physical distance to an entrusted tag. We provide an effective attack of a family of such protocols to implement the spoofing attacks of distance successfully, and description of existing protocols cannot completely eliminate such attacks. Corresponding we propose a new time-stamped program to correct the defect and verify the effectiveness.
