Tracker : security and privacy for RFID-based supply chains

    RACKER, a protocol for object genuineness verification in RFIDbasedRACKER allows to securelyRACKER provides privacy: an adversary can neitherRACKER’s security and privacy is based on anany computation, supply chains. More precisely, T identify which (legitimate) path an object/tag has taken through a supply chain. T learn details about an object’s path, nor can it trace and link objects in supply chain. T extension of polynomial signature techniques for run-time fault detection using homomorphic encryption. Contrary to related work, RFID tags in this paper are not required to perform but only feature a few bytes of storage such as ordinary EPC Class 1 Gen 2 tags.   The counterfeiting of pharmaceutics or luxury objects is a major threat to supply chains today. As different facilities of a supply chain are distributed and difficult to monitor, malicious adversaries can inject fake objects into the supply chain. This paper presents T
