Abstract: Radio frequency identification(RFID) technology has been wildly used, but it is lack of security mechanism and it can not protect its data effectively. By analyzing the security and privacy problems in RFID application, this paper affords a secure communication protocol under the limited computation resources in RFID tag to solve these problems. The protocol adopts Hash function to avoid security attacks such as information leak, counterfeit, orientation tail, etc.

Key words: radio frequency identification (RFID), security, communication, Hash, attack

摘要： 无线射频识别(RFID)技术目前已被广泛应用，但其缺乏安全机制，无法有效地保护RFID标签中的数据信息。该文分析了RFID技术在应用中存在的安全及隐私问题，提出了在RFID标签芯片计算资源有限的情况下解决这些问题的一个安全通信协议。该协议利用Hash函数技术实现了防止消息泄漏、伪装、定位跟踪等安全攻击。
