| 摘 要： | 针对基于Hash函数和密钥更新机制的无线射频识别（RFID）安全协议可能导致数据同步，使得标签认证失败的问题，对几种RFID安全协议保护同步的方法进行分析，指出它们的特点和局限，在此基础上提出基于Hash锁的同步强化RFID安全协议。该协议在数据库记录中添加保护数据同步的密钥Kp，解决了数据同步问题。分析结果表明该协议实现了防止信息泄露、不可追踪性和数据同步等要求，且计算复杂度低。

| Abstract: | The Radio Frequency Identification(RFID) authentication protocol based on Hash lock and key updating may lead to desynchronization which makes the tag-to-reader authentication fall into failure. In the paper, the anti-desynchronization methods of several RFID authentication protocols are analyzed and the disadvantages of which are also pointed out, and a novel scheme, Hash lock-based strengthen synchronization RFID authentication protocol is proposed. The scheme achieves the anti-desynchronization requirement by adding anti-desynchronization Key Kp into the database. Analysis result shows that the new scheme realizes the requirement of anti-information leakage, intraceability and synchronization with a low computing load. |
