A New RFID Privacy Model

This paper critically examines some recently proposed RFID privacy models. It shows that some models suffer from weaknesses such as insufficient generality and unrealistic assumptions regarding the adversary's ability to corrupt tags. We propose a new RFID privacy model that is based on the notion of indistinguishability and that does not suffer from the identified drawbacks. We demonstrate the easy applicability of our model by applying it to multiple existing RFID protocols. © 2011 Springer-Verlag.
