针对供应链中射频识别标签随商品不断流动过程涉及的隐私保护和防伪认证等问题，利用椭圆曲线离散对数问题和传递加密的方法，设计一种兼有防伪功能的所有权转移安全协议。从标签和所有者的巧妙存储入手，贯穿标签鉴权、所有权转移、防伪认证等环节，进一步利用GNY逻辑证明协议的正确性。安全性分析结果表明了该协议能满足所有权转移的安全需求，具有商品防伪认证的辅助功能，与Cheng等方案相比，标签端的计算量明显减少，效率更高。

Radio frequency identification (RFID) tags flowing along with the commodity in the supply chain involves in issues of privacy and security authentication ,for which a secure RFID tag ownership transfer protocol with anti‐counterfeiting property was proposed based on the elliptic curve discrete logarithm problem and transmission encryption .The design of the scheme star‐ted with the clever storage of tags and the owner ,the tag authentication ,transfers of the ownership and security authentication were run through .The correctness of the protocol was proved using the GNY logic .The security analysis shows that the proto‐col not only satisfies the security requirements of ownership transfer ,but also has the property of commodity security certifica‐tion .Compared with Cheng’s solution ,it reduces the computation for the tag .
