一种有效保护隐私及低成本的RFID安全认证协议

An Effective Privacy Protection and Low-cost RFID Security Authentication Protocol

随着RFID技术的逐步应用,隐私安全问题引起人们的极大关注,针对现有的RFID认证协议存在着安全隐私保护弱点及建设成本高、系统性能不稳定等问题,本文提出了一种能有效保护标签隐私数据及低成本的安全认证协议。并对该协议进行安全及性能分析,该协议不仅能有效解决重传攻击、位置隐私攻击、数据不同步等问题,而且极大地利用了读写器计算资源降低系统建设成本,适合RFID系统的应用。

With the gradual application of RFID technology, privacy and security problems arouse people＇s great attention. In view of the weakness in security and privacy protection, high cost and unstable system performance in the existing RFID authentication protocol, this paper puts forward a kind of security authentication protocol with effective protection for label privacy data and low cost, and analyzes its security and function. The protocol cannot only effectively solve the replay attacks, location privacy attack, data desynchronization, but make use of the reader computing resources to reduce the cost of system construction, and is suitable for the application of RFID system.
