中文摘要：

为了设计出一个轻量级的RFID安全认证机制，深入分析了金永明等人提出的所有权转移认证协议，并指出其存在的安全缺陷，在原协议的基础上提出了一个新的所有权转移方案。通过安全分析和性能分析结果表明了该方案是安全的、高效的，除了能符合所有权转移中必须的安全性和隐私性条件，如具备抵抗一些主流攻击的能力，保护所有者的隐私，还能解决原协议存在的安全问题，同时提高认证效率。

英文摘要：

To design a low-cost radio frequency identification （RFID） secure mechanism, a further analysis for Jin＇s ownership transfer authentication protocol is given, it shows that their protocol has some security flaws, and a new protocol is proposed based on Jin＇ s protocol. The security analysis and performance analysis demonstrate the safety and high efficiency of the new protocol. New protocol can not only satisfy the prerequisites for the security and privacy of ownership transfer, such as resisting common attack, but also protect the privacy of new owners and original owners. Moreover, the security flaws in Jin＇s protocol are overcome, and the authentication efficiency is also enhanced.
