基于Hash函数的RFID挑战-应答认证协议

RFID Challenge-Response Authentication Protocol Based on Hash Function

介绍几种典型的射频识别安全隐私保护协议的方法,针对这些协议和一些文献中提出的改进协议中的不足提出一种新的基于Hash函数的改进方案,该方案可以有效地抵御非法读取、位置跟踪、窃听、伪装哄骗和重放等不安全问题,并适用于标签数目和阅读器数目较多的情况,具有较好的安全性和高效性。

This paper introduces several typical methods to against security and privacy problems,and aim at the shortages in them and other improved ones which provided by some literatures,proposes a new improved scheme based on hash function.The modified scheme resists illegal access,tracking,eavesdropping,impersonation and replay attack,fits for the case which the tags and readers number is large and is security and efficiency.
