KP+ : Fixing Availability Issues on KP Ownership Transfer Protocols

Jorge Munilla

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 solve most of the security weaknesses detected in previously published protocols. However, this paper reviews this work and points out that such schemes still present some practical and security issues. We then propose some modifications in these protocols that overcome such problems.
