An Authorization Scheme Using Partial ID for Privacy Protection in RFID

The Radio Frequency Identification (RFID) has recently received much attention from various parties such as supply chain management. It is believed that RFID can bring revolutionary changes to supply chain, replacing the existing barcode systems. However, even though RFID system is widely used for industrial and individual applications, RFID tag has a serious privacy problem, i.e., traceability. To protect the users from tracing and also to support Low-cost RFID, the authors propose an authentication protocol which can be adopted for read-only RFID tag using XOR computation and Partial ID concept. The proposed protocol secure from the RFID Tag security problem and privacy exposure.
