一种改进的RFID安全认证协议的研究

An Improved RFID Security Authentication Protocol

随着RFID技术的发展,其被广泛的应用在众多的场合,然而在多数场合下RFID系统不但追求高安全性而且要求标签的低成本,这就需要一个合适的安全认证协议。该文首先研究了几种典型的安全协议,分析了它们的优缺点,然后提出了一种改进后的基于hash函数的安全认证方案。并通过理论分析了其安全性和可行性;另外通过实验测试了该协议的性能是高效。

With the development of RFID technology,it is widely applied on many occasions,however,in most cases,the RFID system not only pursue the high security,but also require the label's low-cost,which requires an appropriate security authentication protocol.Based on the analysis about authentication process and the disadvantages of the several typical security protocols,this paper proposes an im proved security authentication protocol with hash function and analysis its safety and feasibility;and the experiments proved performance of the protocol.
