Abstract

SummaryIt is now possible to embed radio‐frequency identification tags into almost any physical device. However, issues regarding privacy remain a concern and limit their widespread use. We propose a scalable anonymous radio‐frequency identification authentication protocol using what we refer to as anonymous tickets. These tickets uniquely identify tags and are reusable. This considerably strengthens its non‐traceability and requires just search/query time, with minimal storage overhead on the back‐end system. We formally prove the protocol and compare the performance of the proposed protocol with selected works found in literature. Copyright © 2013 John Wiley & Sons, Ltd.
