A Lightweight RFID Authentication Protocol based on Elliptic Curve Cryptography

The security and privacy of the tag carrier has become the bottle neck of Radio Frequency Identification (RFID) system development further. In this paper, we propose a robust authentication protocol based on Elliptic Curve Cryptography (ECC), which meets the requirement of resource-limited RFID systems. Our protocol achieves mutual authentication and possesses lightweight feature by reducing the computation cost over the tag end. Moreover, the proposed protocol possesses remarkable security properties in RFID system and the immunity against the possible malicious attacks as well as an excellent performance through the detailed security analysis. Performance evaluation and function comparison demonstrate that our protocol makes a balance between cost and security in RFID authentication protocol. Compared to the previous relevant RFID authentication protocols, our protocol improves efficiency, enhances robustness, which is well suitable for RFID tags with the scarceness of resources.
