射频识别(RFID)作为一种标签系统被广泛使用，以方便现实世界中的物理交易。由于廉价的无源射频标签的出现，RFID技术现在是物联网的催化剂，即可以像互联网一样唯一地识别每个物体。在未来，许多独立的RFID系统很可能被集成到几个亿级的RFID系统中。在集成的RFID系统中，提供基于RFID的数据服务的服务提供商(SP)和使用数据服务的客户是不同的组织。因此，数据真实性方面的质量令人严重关切。在本文中，我们首先描述了RFID系统中的数据验证问题，并建立了存在多个SP和客户端的集成RFID系统的模型。然后，我们提出了两种数据验证协议，以确保与特定标签相关联的SP生成的数据没有被修改。此外，我们将我们的系统作为一个原型来实现。计算机仿真、分析和基于原型的测试平台均表明，所提出的可验证集成RFID系统具有较高的安全性和性能。
Radio frequency identification (RFID) is widely used as a tagging system to facilitate physical transactions in the real world. Thanks to the availability of inexpensive passive RF tags, RFID technology is now the catalyst of Internet of Things, i.e., every object can be uniquely identified in an Internet-like way. In the future, many individual RFID systems are likely to be integrated into a few exascale RFID systems. In an integrated RFID system, service providers (SPs) that offer RFID-based data service and clients that use the data service are different organizations. As a consequence, quality of data in terms of authenticity is of significant concern. In this paper, we first formulate a data verification problem in RFID systems and build a model of integrated RFID systems where multiple SPs and clients exist. Then, we propose two data verification protocols to ensure data generated by SPs associated with a particular tag and has not been modified. In addition, we implement our system as a prototype. The computer simulations, analyses, and testbeds based on the prototype all demonstrate that the proposed verifiable integrated RFID system achieves a high level of security and performance.
