射频识别(RFID)标签是一种小型廉价的设备,它结合在IC芯片和天线中用于无线电通信。RFID标签用于商品的管理,并用作条形码的替代品。然而,RFID系统可能会侵犯消费者的隐私,因为它具有很强的追踪能力。在本文中,我们提出了一个密钥变更方案,可以防止前所有者阅读RFID标签后,改变其所有者。通过使用我们的方案,以前的所有者无法读取和跟踪RFID标签上的ID信息。此外,由于我们的方案只使用对称密钥加密技术,因此可以将联合收割机其他的隐私保护方案与我们的方案结合起来。
A Radio-Frequency-Identification (RFID) tag is a small and cheap device which is combined in IC chip and an antenna for radio communications. The RFID tag is used for management of goods and used as a substitute for a bar code. However, RFID system may infringe on a consumer’s privacy because it has a strong tracing ability. In this paper, we propose a key change scheme which can prevent previous owner from reading the RFID tag after changing its owner. By using our scheme, previous owner cannot read and trace ID information on the RFID tag. Moreover it is possible to combine other privacy protection scheme with our scheme because our scheme uses only symmetric key cryptography.
