Secure attribute-based search in RFID-based inventory control systems

摘要

We develop a secure attribute-based search protocol for Radio Frequency Identification (RFID) systems. This protocol can be used to simultaneously identify groups of items that share a set of attribute values. To the best of our knowledge, this is the first such work with the potential to significantly enhance the security and intelligence of RFID-enabled applications in inventory control and supply chain management. The protocol is designed to be lightweight, suited for resource-constrained basic passive tags, and compliant with the Electronic Product Code (EPC) standards. This is achieved by exploiting the zero knowledge properties of quadratic residues. The security and privacy properties offered by the protocol are rigorously proven through formal verification.
