It 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 O1 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.
