一种改进的超轻量级RFID所有权转移协议

针对RFID所有权转移协议中存在的拒绝服务攻击漏洞,提出了一种改进的超轻量级RFID所有权转移协议,并给出了基于GNY逻辑的协议安全性证明。通过改进协议的交互方式,实现了阅读器和标签的双向认证功能,解决了攻击者重放消息造成的拒绝服务攻击漏洞等问题,提高了阅读器和标签在开放环境中通信的保密性。对协议的安全性分析和性能比较分析表明,该协议不仅满足所有权转移的安全要求,而且具有超轻量的特点,适合于移动身份认证环境中的实际应用。

Improved Ultra-lightweight Authentication of Ownership Transfer Protocol for RFID Tag

Aiming at the securing hole of current ownership transfer protocol,a ultra-lightweight RFID mutual aut- hentication of ownership transfer protocol was proposed.The formal proof of the proposed authentication protocol was given based on GNY logic.It improves the reader and the tag in an open environment confidentiality of communications,which not only solves problems of Denial of Service (DoS) that are produced when the attacker replays the message,but also achieves the reader and the tag mutual authentication function through changing protocols interact.This paper analyzed the security and compared the performance of the protocol.The results show that the proposed protocol not only satisfies the security requirements of transfer of ownership,but also has the characteristics of ultra-lightweight,which indicates that it is suitable for actual mobile authentication environment.
