摘　　要：针对现有基于Hash函数射频识别(RIFD)安全认证协议中由于阅读器假冒而引起的安全问题,以及认证协议效率不高的缺陷,提出了一种新的基于Hash函数的RFID安全认证协议,并将其安全性与其他协议进行对比,采用形式化分析方法对其安全性进行了证明。通过理论分析和形式化证明,证明了该协议能保护标签的数据隐私,保证数据同步,防止标签被跟踪,防止信息重放,防止克隆假冒,并且具有向前安全性,适用于低成本的电子标签。Considering that the current RFID security authentication protocol based on the Hash function has many security problems because of fake readers, and that it also has the weakness of low authentication protocol efficiency, a new RFID security authentication protocol based on the Hash function was put forward. The security ability of the protocol was compared with other protocols and proved by formal analysis. Theoretical analysis and formal proof show that the protocol can protect the data privacy, achieve the data synchronization, prevent the tag from location tracking, avoid information reproduction and prevent clone and counterfeit. The protocol also possesses forward security abihty and it is useful for low-cost tags.
