中文摘要：

对匿名RFID身份认证协议（ARAP）进行深入的分析，发现其存在无法抵抗假冒攻击和阅读器功能受限等方面的缺陷，提出相应的改进方案，并对改进后的协议进行全面的安全性能分析。结果表明，改进后的ARAP协议能够抵抗假冒、拒绝服务等诸多攻击，安全性能有所增强，且协议执行的计算量明显减少，具有较高的可行性。

英文摘要：

The anonymous RFID authentication protocol(ARAP)is analyzed,and its defects that it cannot resist counter?feiting attack and overcome limitation of reader function are found. The corresponding improvement scheme is proposed. The com?prehensive analysis on security performance of the improved scheme is carried out. The result shows that the improved ARAPcan resist attacks such as counterfeiting,denial of service and so on,its security performance is enhanced,and the calculatedamount of the protocol implementation is significantly reduced. Therefore,the improved ARAP has high feasibility.
