摘要
近年来,射频识别(RFID)技术得到越来越多的应用,随之而来的是各种RFID安全问题。对现有的基于Hash函数的RFID认证协议进行分析,针对现有技术存在的不足,提出了一种基于Hash函数的低成本的RFID双向安全认证方法,该方法只需要进行一次Hash函数计算,且加入了标签ID动态更新机制,通过在后台数据库中存储旧的标签ID解决同步问题,与现有技术相比具有一定的优越性。
In recent years, radio frequency identification (RFID) has been widely used, which causes a lot of security and privacy problems. After analyzing current RFID security authentication methods based on hash function, a low-cost RFID mutual authentication method based on hash function is proposed according to deficiencies of current methods. In this method, Hash function is operated only once and the tag's ID can be refreshed dynamically. To solve the synchrony problem the old ID of tags are also stored in back-end database. Compared with current RFID authentication methods, the method proposed in this paper performs better.
