摘　　要：针对传统射频识别(Radio-frequency identification,RFID)技术成本高以及读写器与标签之间认证系统薄弱的问题,提出了一种RFID标签-读写器双向认证协议。引入了截断乘法器作为加密器以减少硬件成本和动态功耗,利用16位线性反馈移位寄存器产生随机数和模式序列,使用现场可编程门阵列(field programmable gate array,FPGA)器件对协议进行硬件实现。可进行双向认证,可有效抵抗欺骗、应答攻击、中间人攻击等恶意行为。使用Altera Quartus II工具对协议进行仿真,结果显示,协议在区域和动态功耗及安全方面的性能优于其他几种较新的协议。To solve the problem of high cost and weak authentication systems between reader and tag in tradition Radio-frequency identification （RFID）, a protocol for RFID tag-reader mutual authentication scheme is proposed. Firstly, the proposed protocol communication between a reader and a tag is described. Then the truncated multipliers are introduced as encrypter to reduce hardware cost and dynamic power. Finally, the proposed protocol is implemented by using Fild Programmable Gate Array （FPGA） The experiment results show that our proposed protocol outperforms the earlier schemes in terms of area, dynamic power dissipation and security.
