摘　　要：椭圆曲线加密系统的理论基础是椭圆曲线离散对数问题。与其他公钥密码系统相比,该加密系统具有安全性高、密钥长度短和计算量小等优点,近年来逐渐被应用于RFID认证中。该文首先研究了国外一种基于椭圆曲线加密的认证协议。该协议采用最小的计算量达到安全认证的目的,分析证明该协议易受重放攻击、窃听攻击和标签假冒攻击。在此基础上,提出了一种更为简单和安全的改进协议。The theoretical basis of elliptic curve crypto system （ECC）was elliptic curve discrete Logarithm problem （ECDLP）. Compared with other asymmetric cryptography,ECC has stronger security,shorter key length and less com- putation. So ECC can be applieated in the authentication of radio frequency identification （RFll））in recent years, whose resources were extremely limited. Firstly,this paper studied a protocol that minimized the cryptographic effort on RFID tag. However,it were proved that the protocol can not resist replay attack,eavesdropping and tag imperson- ation attack. On this basis,propose a simpler and more secure improved protocol.
