Tag Ownership Transfer in Radio Frequency Identification Systems: A Survey of Existing Protocols and Open Challenges

Radio frequency identification (RFID) is a modern approach to identify and track several assets at once in a supply chain environment. In many RFID applications, tagged items are frequently transferred from one owner to another. Thus, there is a need for secure ownership transfer (OT) protocols that can perform the transfer while, at the same time, protect the privacy of owners. Several protocols have been proposed in an attempt to fulfill this requirement. In this paper, we provide a comprehensive and systematic review of the RFID OT protocols that appeared over the years of 2005-2018. In addition, we compare these protocols based on the security goals which involve their support of OT properties and their resistance to attacks. From the presented comparison, we draw attention to the open issues in this field and provide suggestions for the direction that future research should follow. Furthermore, we suggest a set of guidelines to be considered in the design of new protocols. To the best of our knowledge, this is the first comprehensive survey that reviews the available OT protocols from the early start up to the current state of the art

Shared RFID ownership transfer protocols

Radio Frequency Identification (RFID) has been widely adopted in practice for objects identification. The ownership of an object can be represented by the ownership of the RFID tag attached to the object. An ownership could be shared among different parties and should be transferable. Although many RFID ownership transfer protocols were proposed, a shared ownership transfer protocol remains as a daunting task with absence of a trusted party. In this paper, we propose the first provably secure shared ownership transfer protocol, which requires merely hashing computations and has a constant key size
