| 摘要 |
在低成本电子标签中实现安全隐私功能是RFID研究领域需要解决的一项关键技术．该文提出了一种新的解决途径：将物理方法和密码机制相结合，其主要特点是在标签中不使用Hash锁，但在阅读器中采用，这样在标签中大约可节省2万多门电路。此外，为防止非法阅读器的窃听。还设置了多个假名。能够有效地抵抗假冒攻击和重传攻击。最后将该安全策略应用到RFID防冲突算法中，得到一种低成本、安全、实用的二进制防冲突算法。

The method of implementation of security and privacy in low cost RFID tags is a key technique which needs to be solved in research field．This paper proposes a new solution which combines physical method with encryption and the main features are that Hash lock is not applied in tags，rather than is used in readers．By employing this technique，more than 20000 gate circuits will be reduced in tags．Furthermore，several pseudonyms are also adopted to prevent an unauthorized reader from eavesdropping，which can effectively resist counterfeiting attack and relay attack．Finally，a low cost，security and practical binary anti-collision algorithm is developed in this paper by adopting the suggested security architecture to RFID anti-collision algorithm．
