Protocol for Simultaneous Ownership Transfer of Multiple RFID Tags with TTP

Abstract

Ownership transfer of items that are RFID-tagged require more than physical means to accomplish the process. Their inherent ability to communicate with entities that are not necessarily in their close proximity necessitates supplementary ownership transfer measures that complement the transfer of the physical item. Over the past few years, several ownership transfer protocols have been developed with the explicit purpose of transferring ownership of a tag from one owner to another. While it generally suffices to transfer ownership of tags one by one, sometimes it is necessary to simultaneously transfer ownership of multiple tags from one owner to another. This is especially true when multiple items are required to belong together during and outside of the ownership transfer process. Extant literature on RFID ownership transfer protocol, however, does not consider this scenario. We propose a protocol that attempts to address this gap in the literature.
