基于射频指纹的高安全强度RFID认证协议

Security enhanced RFID authentication protocol based on RF fingerprint

在分析现有基于(EPC Class 1Gen,2EPCGen2)标准的轻量级RFID相互认证协议的基础上,提出了一种符合EPCGen2标准的基于射频指纹的RFID认证协议。协议融合了RFID设备的物理层信息,实现了RFID标签的跨层融合认证,具有增强RFID系统安全强度的特点。分析显示,提出协议具有相互认证、私密性、防止重放攻击、防止去同步攻击等安全性能,尤其能有效对抗RFID标签的克隆攻击。

With the analysis of the current lightweight RFID mutual authentication protocols based on EPCGEN-2 standard, a novel RFID authentication protocol based on RF fingerprint is proposed, which corresponds with EPCGEN-2 standard. The proposed protocol combines the physical layer information of RFID equipment, implements the cross-layer fusion authentication of RFID tags, and has the characteristics of enhancing security density of RFID system. The result of analysis demonstrates that the proposed protocol has the security properties such as mutual authentication, privacy, preventing replay attack and the desyn- chronization attack, especially effectively resisting tag cloning attack.
