RFID Mutual Authentication Scheme based on Synchronized

Radio Frequency IDentification (RFID) is an automatic identification system, relying on storing and remotely retrieving data about objects we want to manage using devices called “RFID tag”. Even though RFID system is widely useful for industrial and individual applications, RFID tag has a serious privacy problem, i.e., traceability. To protect users from tracing, we propose an RFID mutual authentication scheme which utilizes a hash function and synchronized secret information like others. To the best of our knowledge, our scheme offers the most enhanced security feature in RFID mutual authentication scheme with respect to user privacy including resistance against tag cloning allowing an additional hash operation.
