摘要
为了提高大规模RFID系统的认证效率,通过分析现有RFID系统的认证效率和安全性,提出了一套基于Hash函数的改进协议。向RFID读写器加入过滤规则,能够有效过滤恶意和无效的认证请求;对标签的访问计数器值的分层化、更新和重置,可以有效提高后端数据库检索数据的命中率。通过分析和测试,该协议能够有效抵御假冒攻击、重传攻击等不安全问题,有效提高RFID认证的效率,降低认证服务器计算负荷。
In order to improve the certification efficiency of large-scale RFID system, a set of improved protocols based on Hash function are proposed by analyzing the certification efficiency and safety of existing RFID systems. Joining the filtering rules into RFID reader can effectively filter malicious and invalid authentication request. The stratification, updating and resetting of tag access counter＇s value can effectively improve the hit rate of the retrieving data in back-end database. The analysis and testing results show that the protocols can effectively resist the fake attack, replay attack and other unsafe problems. In addition, the protocols can improve the efficiency of RFID authentication and reduce the computational load of authentication server effectively.
