Defining Strong Privacy for RFID

In this work, we consider privacy in radio frequency identification (RFID) systems. Our contribution is twofold: (1) we propose a simple, formal definition of strong privacy useful for basic analysis of RFID systems, as well as a different (weaker) definition applicable to multi-verifier systems; and (2) we apply our definition to reveal vulnerabilities in proposed privacy-enhancing RFID protocols.
