A Scalable and Secure RFID Ownership Transfer Protocol

Ownership transfer in an RFID inventory system experiences many security and privacy oriented problems. We consider scenarios related to ownership transfer of RFID tags in a large inventory system. In this paper, we propose a new mutual authentication protocol from Ring LPN problem that leverages the reader authentication phase to incorporate Semi-Trusted Parties (STP) seamlessly in RFID ownership transfer protocol. Employing STPs could ease the ownership transfer process for the consumers in the remote location. More precisely, we introduce a new variant of Learning Parity from Noise (LPN) based mutual authentication scheme for efficient ownership transfer protocol where ownership of multiple tags can be transferred from one owner to another by taking advantages of an efficient homomorphic aggregated signature (HomSig) and pseudo-inverse matrix properties. To the best of our knowledge, this is the first RFID ownership transfer protocol from LPN problem that is secure, private and scalable under standard model.
