摘　　要：随着物联网的发展和无线射频识别技术(radio frequency identification,RFID)的广泛应用,RFID系统的安全问题越发突出。其中克隆标签的出现极大地阻碍了RFID系统的大规模发展,成为当前一个亟待解决的难题。通过总结分析目前RFID克隆标签检测领域的一些主流方法,旨在为后续研究更有效的RFID克隆标签检测策略奠定基础。针对目前已知的一些检测方法,该文将克隆标签检测方法归纳总结为射频指纹、同步秘密、轨迹分析和碰撞检测四大类,并较为系统地对这四大类方法所包含的具体策略进行了研究,同时对这些方法策略进行了横向与纵向的对比分析。目前这四类方法都存在一定的缺陷,导致其无法直接应用于现有RFID系统进行克隆标签检测或者应用条件较苛刻。针对目前这些方法存在的问题,认为匿名RFID系统克隆标签的分布式检测是未来的一个主要研究方向。With the development of the Internet of Things and the wide application of radio frequency identification,the security problem of RFID system is becoming more and more prominent.Among them,the emergence of clone tags greatly threatens the life and property safety of producers and consumers,which has become an urgent problem to be solved.At present,some mainstream methods in the field of RFID clone tag detection are summarized and analyzed,aiming to lay the foundation for further research on more effective RFID clone tag detection strategies.According to some known detection methods,clone tag detection methods are summarized into four categories:radio frequency fingerprint,synchronization secret,trajectory analysis and collision detection.The specific strategies contained in these four categories are systematically studied.At the same time,these methods are compared horizontally and vertically,and the evaluation conclusions are shown in the form of tables.At present,these four methods have been found to have certain defects after analysis,which makes them unable to be directly applied to the existing RFID systematic clone tag detection or the application conditions are harsh.In view of the existing problems of these methods,the distributed detection of clone tags in anonymous RFID systems is identified as a direction that needs to be worked in the future.
