中文摘要：

作为未来物联网（IOT）的核心技术之一,无线射频识别（RFID）系统由于设备的局限性而存在许多安全问题.在分析几种典型安全协议核心思想的基础上,提出了基于二维区间（two-dimensional region,TDR）Hash链的安全协议.该协议以区间划分的方式标识各链,从而提高了数据库的检索效率;同时,由于在协议中引入了随机性,RFID系统的安全性得到了进一步增强.

英文摘要：

Due to the limitation of relevant devices,a lot of security problems exist in a radio frequency identification（RFID） system,one of the core technologies of the future internet of things（IOT）.A new protocol based on the two-dimensional region（TDR） Hash chains was proposed after the core ideas of several typical RFID cryptographic protocols were analyzed.TDR could significantly improve the efficiency of database retrieval by identifying each Hash chain with region division.Moreover,a random number was introduced to further enhance the security of RFID systems.
