In this paper, the authors present a fine-grained view of an RFID- enabled supply chain and tackle the secure key distribution problem on a peer-to-peer base. In their model, they focus on any pair of consecutive parties along a supply chain, who agreed on a transaction and based on which, certain RFID-tagged goods are to be transferred by a third party from one party to the other as in common supply chain practice. Under a strong adversary model, they identify and define the security requirements with those parties during the delivery process. To meet the security goal, they first propose a Resilient Secret Sharing (RSS) scheme for key distribution among the three parties and formally prove its security against privacy and robustness adversaries.
