A fair exchange and track system for RFID-tagged logistic chains
2015
RFID (Radio-Frequency IDentification) is attractive for the strong visibility it provides into logistics operations. In this paper, we explore fair-exchange techniques to encourage honest reporting of item receipt in RFID-tagged supply chains and present a fair ownership transfer system for RFID-tagged supply chains. In our system, a receiver can only access the data and/or functions of the RFID tag by providing the sender with a cryptographic attestation of successful receipt; cheating results in a defunct tag. Conversely, the sender can only obtain the receiver's attestation by providing the secret keys required to access the tag.
