Study on UHF RFID Authentication Protocol

With the advantage of long distance, high speed and low cost, the UHF RFID technology has become a hot research area of RFID and it will become a fundamental technology of future information society construction. Because of the openness of RFID, RFID application takes a risk of being attacked, security and privacy issues become a constraint bottleneck to its further development. To solve the existing problems of UHF RFID authentication protocol, the article proposed a reliable RFID authentication protocol. The new protocol solves many security problems including mutual authentication, anonymity, untraceability, anti-impersonation and anti-replay.
