摘　　要：以动物产品溯源方案的安全性为研究对象,研究了基于RFID技术的动物产品溯源方案的接入认证技术,设计了一个适用于低成本动物产品溯源的高效可靠RFID认证方案。结果显示:该方案在整个认证过程中巧妙地配置了后端数据库和标签的操作,后端数据库只进行两次双线性对运算,标签无需进行任何计算操作,不仅极大地提高了网络的整体响应效率,同时适用于低成本标签的接入认证,便于动物产品溯源系统进行实时通信。结果表明:该方案保证了标签身份的隐私,防止了标签的伪造,保护了名牌食品的利益。因此,该方案非常适用于低成本动物产品溯源系统的可靠通信。The security of traceability system for animal products was selected as the research object. The research on the access authentication technology of RFID-based traceability system of animal products was carried out. An efficient secure RFID authentication scheme used in traceability system of animal products was proposed. The results showed that the Tag and back-end database were properly configured with different workloads. This scheme only needed two pairing computations for any group size in the back end database and no computation in Tag in order to enhance the network efficiency, aiming to ensure the real-time traceability, which was great fit for the low-cost Tag. The results concluded that the proposed scheme ensured the Tag＇s privacy, prevented the counterfeit of labels and protected the interests of brand name food products. Therefore, the proposed scheme was well suitable for security communication of the low-cost traceability system of animal products.
