无线射频识别技术在各领域的标签认证协议的研究

Research on RFID Tag Authentication Protocol in Various Fields

射频识别技术(RFID)已经大量在各个领域使用,RFID标签和阅读器之间是通过无线通信交换数据的,在通信过程中存在着信息篡改、盗用、泄露等威胁,因此研究者们提出了很多基于RFID标签的认证协议,但是RFID标签存在着处理能力弱,存储空间小和电源供有限等局限性,所以针对不同的EFID标签结构和系统安全要求设计采用最适合的标签认证协议是非常重要的,本文对目前主流的几种RFID标签认证协议以及它们的改进协议的工作机理进行了分析,并讨论了各自的适用性,对RFID系统的安全性设计和实施有积极的意义。

The radio frequency identification（ RFID） has been widely used in various fields. Between the RFID tag and the reader is to exchange data through wireless communication. The communication exists in the process of information tampering,theft,leakage and other threats,so the researchers proposed many authentication protocols based on RFID label. But there are RFID label processing weak,small storage space and power supply limited. So according to different EFID tag structure and system safety design requirements using the most suitable tag authentication protocol is very important. The working mechanism of some popular RFID tag authentication protocol and the improved protocol are analyzed,and is discussed. The positive significance to the safety of the RFID system design and implementation.
