摘　　要：针对现有基于椭圆曲线密码(elliptic curve cryptography,ECC)体制的RFID(radio frequency identification device)安全认证方案不能满足相互认证、隐私保护和前向安全性等要求,提出一种基于Montgomery型椭圆曲线密码的认证方案。利用Montgomery型椭圆曲线来降低计算量,并提供标签和服务器之间的相互认证,具有匿名性和前向安全性。通过分析表明,该方案能够抵抗重放攻击、标签伪装攻击、服务器欺骗攻击、Do S攻击、位置跟踪攻击和克隆攻击。与现有方案相比,该方案在保证较低的内存、计算和通信需求的情况下,提供了较高的安全性能,能够满足RFID系统的安全性要求。For the issues that the existing RFID security authentication scheme based on elliptic curve cryptography（ECC） can not meet the requirements of mutual authentication, privacy protection and forward security, a RFID security authentication scheme based on Montgomery-form elliptic curve cryptography was proposed. This scheme uses the Montgomery elliptic curve to reduce the amount of computation, and to provide mutual authentication between the label and the server, and anonymity and forward security. The analysis showed that the scheme could resist replay attack, tag camouflage attack, server cheat attack, Do S attack, position tracking attack and clone attack.Compared with the existing schemes, the proposed scheme provides high security performance under low memory,computation and communication requirements, and it can meet the security requirements of the RFID system.
