基于ID变化的RFID安全协议

RFID cryptographic protocol based on ID change

提出了一种基于ID变化的RFID安全协议,由于使用单向Hash函数,从而使数据存储机制很好地解决了阅读器和标签数据不同步的问题,有效地防止了非法读取、位置跟踪、窃听、伪装哄骗、重放等攻击。分析表明,该方法具有前向安全,效率高,安全性好等特点,适用于标签数目较多的情况。

A RFID cryptographic protocol based on ID change was proposed. Through taking in one-way Hash function and specific data storage mechanism, the problem of reader and tag data synchronization were solved. This approach efficiently prevents unauthorized reading, location track, counterfeit and spoofing, replay attack and so on. Analysis shows that this approach is forward secure, high efficiency, good security and fits for the scenario when the tags number is large.
