Abstract—Ownership Transfer Protocols for RFID allow transferring the rights over a tag from a current owner to a new owner in a secure and private way. Recently, Kapoor and Piramuthu have proposed two schemes which overcome most of the security weaknesses detected in previously published protocols. Still, this paper reviews that work and points out that such schemes still present some practical and security issues. In particular, they do not manage to guarantee the privacy of the new owner without the presence of a Trusted Third Party, and we find that the assumed communication model is not suitable for many practical scenarios. We then propose here a lightweight protocol that can be used in a wider range of applications, and which incorporates recently defined security properties such as Tag Assurance, Undeniable Ownership Transfer, Current Ownership Proof and Owner Initiation. Finally, this protocol is complemented with
