An RFID Ownership Transfer Protocol based on multiple owners and different weights

Abstract

In recent years, Radio Frequency Identification (RFID) has become an important technology in the supply chain management. With an RFID tag attached to the product, it will be transferred to consumers through material suppliers, manufacturers, and wholesalers. In a specific case, an item represented by an RFID tag will have multiple owners, and one owner will also own multiple RFID tags. Also, each owner has different weights for different tags. Furthermore, partial ownership of RFID tags can also be transferred between users. This paper proposes a management protocol that uses a trusted third party (TTP) to manage ownerships, which not only ensures the correctness of the transfer between ownerships, but also requires a minimal amount of computation for RFID tags. Finally, we show that the proposed method is resistant to most of the known RFID attacks.
