RFID Authentication Protocol: A Review

RFID (Radio Frequency Identification) is recently becoming popular due to its convenience and economical efficiency. Furthermore, RFID nowadays comes into the spotlight as a technology to substitute the barcode. On the other hand, RFID is jeopardized from various attacks and problems as an obstacle of widespread RFID deployment: replay, spoofing, traceability, de-synchronization, un-scalability, and tag cloning. We focus ourselves on the un-traceability and scalability in this paper. In this paper we will propose two authentication protocols for RFID systems. First, we will present an authentication protocol without proxy and its working. After that we will focus on another authentication protocol with proxy, including the properties of the proxy, and how it helps in authentication.
