Abstract: Within the wider spread of RFID technology, all kinds of identity deception attacks aiming at RFID tags and readers grow up. To ensure the security and privacy in this communication, the RFID tags and readers need to identify them each other, thus the system will create a credible communication channel. This paper proposes a mutual authentication protocol based on elliptic curve cryptography and zero knowledge authentication, and proposes a dynamic tag-ID technology, solving the sniffing, tracking attacks and other issues efficiently.
