Privacy is a major concern in RFID systems, especially with widespread deployment of wireless enabled interconnected personal devices. In this paper, the authors consider privacy issues in RFID systems where the authorized readers must be able to identify tags without an adversary being able to trace them, and provide a formal security model for privacy in RFID system. Under this model, they analyze the recently proposed RFID authentication protocol named anonymous RFID authentication protocol and show attacks on them that compromise the privacy.
