A Novel Authentication Protocol with Soundness and High Efficiency for Security Problems

Recently the concern about security and privacy issues of RFID tags have emerged just because of the vital information in the operation of the RFID system at open radio frequency circumstance. To overcome these threats, this paper presents a mutual authentication mechanism, renewing the tag´s key value in each process, which can solve the problem such as privacy or wiretapping, replay attack, forward security, synchronization indistinguishability or location track and ownership transfer. In view of the cost of tags, we only utilize the symmetric encryption in RFID authentication protocol. Analysis shows that this approach is of good security and privacy, low cost, and high efficiency.
