A Study on Authentication Protocol in offering Identification Synchronization and Position Detection in RFID System

It has been estimated that 'RFID' technology would be playing an important role in the incoming ubiquitous environment. But, the communication between tag and reader in RFID system has been conducted by wireless communication of radio frequency so that the information on identification could be eavesdropped by the third party maliciously. Such eavesdropped information could be also used as basic information in attaching others; in this regard, it could impair the privacy of its users and the users have avoided using 'RFID.' Therefore, many studies have been performed and the output of Tag has been varied by means of updating the ID in order to solve such a problem. Though, the ID synchronization between database and tag should be done in the ID update process. Therefore, in this paper, we propose a RFID authentication protocol which offers synchronization.
