An Improved Security Authentication Protocol for Lightweight RFID Based on ECC

Abstract

The security, privacy, and operation efficiency of radio frequency identification (RFID) must be fully measured in practical use. A few RFID authentication schemes based on elliptic curve cryptography (ECC) have been proposed, but most of them cannot resist the existing attacks. The scheme presented by Qian et al. could not resist impersonation attack according to our security analysis. Then, we propose a novel lightweight RFID authentication scheme, which is proved that it can resist server spoofing attack, tag masquerade attack, and provide other security properties of a RFID authentication scheme. Comparisons of computation and communication cost demonstrate that the proposed scheme is more suitable for the resource-constrained RFID authentication.
