Defining Strong Privacy for RFID

Ari Juels and Stephen A. Weis

Abstract

In this work, we consider privacy in Radio Frequency IDentification (RFID) systems. Our contribution is threefold: (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; (2) We apply our definition to reveal vulnerabilities in several proposed privacy-enhancing RFID protocols; and (3) We formally analyze and suggest improvements to ``Hash-Locks,'' one of the first privacy-enhancing RFID protocols in the literature.
