RFID tags are becoming more and more widespread, but their privacy issue has remained yet as a major concern. Due to resource limitations on these tags, providing the privacy is challenging while it is undoubtedly critical before their full deployment. A considerable number of protocols have been proposed, improved over the time and crypt analyzed to provide descent solutions to RFID privacy problem, each of which with strengths and weaknesses. This paper addresses privacy weaknesses of some of them and in the main part of this paper; we propose a scalable anonymous RFID authentication protocol and describe its design and implementation issues. Our protocol mainly substitutes the hash function used for identification with anonymous tickets, which uniquely identify tags and are reusable. As the result, it considerably strengthens untraceability feature and it needs just O(1) search time and query with small storage overhead on the back-end system.
