RFID作为一种有效的防伪手段已被广泛采用。基于安全协议的遗留系统要么太重，被动标签负担不起，要么遭受各种协议层攻击，例如逆向工程、克隆、侧信道。在这项工作中，我们提出了一个新的防伪系统，TagPrint，使用COTS RFID标签和阅读器。利用被动标签实现低成本和离线真实性验证一直是一项艰巨的任务。我们的系统通过利用一些联邦标签的指纹和几何关系来实现这三个目标。在TagPrint中，我们利用COTS RFID阅读器提供的后向散射信号的相位值提取一种新的指纹，称为相位指纹。为了进一步解决分离问题，我们设计了一个几何解来验证真伪。我们已经使用COTS RFID设备实现了TagPrint的原型。该系统已经对超过6000个标签进行了广泛的测试。结果表明，新指纹具有良好的均匀分布适应度，系统防伪的平均错误率为0.1%。
RFID has been widely adopted as an effective method for anti-counterfeiting. Legacy systems based on security protocol are either too heavy to be affordable by passive tags or suffering from various protocol-layer attacks, e.g. reverse engineering, cloning, side-channel. In this work, we present a novel anti-counterfeiting system, TagPrint, using COTS RFID tags and readers. Achieving a low-cost and offline genuineness validation utilizing passive tags has been a daunting task. Our system achieves these three goals by leveraging a few of federated tags' fingerprints and geometric relationships. In TagPrint, we exploit a new kind of fingerprint, called phase fingerprint, extracted from the phase value of the backscattered signal, provided by the COTS RFID readers. To further solve the separation challenge, we devise a geometric solution to validate the genuineness. We have implemented a prototype of TagPrint using COTS RFID devices. The system has been tested extensively over 6,000 tags. The results show that our new fingerprint exhibits a good fitness of uniform distribution and the system achieves a surprising Equal Error Rate of 0.1% for anti-counterfeiting.
