为了确保RFID系统标签数据的完整性和安全性，将双私钥椭圆曲线加密算法应用在RFID系统的身份认证协议中。选取两个椭圆双曲线基点，每个点对应一个私钥，第一个基点用来隐藏RFID系统的标签ID，防止追踪攻击；第二个基点隐藏随机数，防止重放攻击。用椭圆曲线加密算法对标签数据的加密过程代替传统协议中的哈希函数对标签数据的摘要过程，保证标签数据的完整性。结果表明，协议可以有效保护标签数据的完整性和安全性，防止伪装阅读器攻击和伪装后台服务器攻击。

In order to ensure the safety of the RFID tag data integrity and RFID system, it is proposed that in the elliptic curve encryption double private key and double G-spot authentication protocol of RFID system, the protocol will hide tag ID in the first G point to prevent track attack.The process of Elliptic curve encryption algorithm to tag data encryption will replace the abstract process of tag data with hash function, at the same time calculate second G point.The results show that, the protocol can not only pro-tect the integrity and security of tag data, but also prevent attacks of spoofing reader and the server.
