ECC-Based RFID Authentication Protocol

The radio frequency identification (RFID) technology has been widely used so far in industrial and commercial applications. To develop the RFID tags that support elliptic curve cryptography (ECC), we propose a scalable and mutual authentication protocol based on ECC. We also suggest a tag privacy model that provides adversaries exhibiting strong abilities to attack a tag’s privacy. We prove that the proposed protocol preserves privacy under the privacy model and that it meets general security requirements. Compared with other recent ECC-based RFID authentication protocols, our protocol provides tag privacy and performs the best under comprehensive evaluation of tag privacy, tag computation cost, and communications cost.
