中文摘要：

随着信息科学与技术的快速发展,射频识别（RFID）技术被应用到越来越多的场合,给人们带来了诸多便利。但是,RFID技术存在一些安全隐患。例如,攻击者可以窃取RFID系统通信过程中的重要信息,进行克隆等攻击。物理不可克隆函数（PUF）是解决克隆问题的有效技术手段,基于PUF的RFID系统可以很好地达到防伪要求。文章首先对目前RFID系统存在的伪造情况进行概述和分析,进而提出防伪的必要性。然后从公钥密码技术和私钥密码技术两个方面对目前基于PUF的RFID主要防伪技术做了一个比较全面的综述,总结不同方案的优缺点。

英文摘要：

With the fast development of information science and technology, radio frequency identifi cation（RFID） technique has been used in more and more scenarios, which brings people a lot of conveniences. However, RFID technique has some potential security problems. For example, an attacker can steal important information from the communication process of the RFID system, and then complete the clone attack. Physical unclonable function（PUF） is an effective method to solve the problem of cloning. Based on PUF, RFID system can serve the anti-counterfeiting purpose well. This paper summarizes and analyzes the situation of counterfeiting existing in the RFID system, and then points out the necessity of anti-counterfeiting. This paper gives a comprehensive summary for PUF-based RFID anti-counterfeiting techniques from two aspects： public key cryptography and secret key cryptography, and summarizes the advantages and disadvantages of these different schemes.
