本文介绍了一种基于物理不可克隆功能(PUF)技术的新型现场可编程门阵列(FPGA)识别生成器电路。新的标识生成器能够将触发器延迟路径变化转换为唯一的 n 位数字标识符 (ID),同时通过使用形成为硬宏的 1 位 ID 单元,每个 ID 位只需要一个片。示例性 128 位标识生成器在 10 个 Xilinx Spartan-6 FPGA 器件上实现。实验结果表明,在 25°C 至 70°C 温度范围和电源电压波动 10% 的情况下,独特性为 48.52%,可靠性为 92.41%。
In this paper, a new field-programmable gate array (FPGA) identification generator circuit is introduced based on physically unclonable function (PUF) technology. The new identification generator is able to convert flip-flop delay path variations to unique n-bit digital identifiers (IDs), while requiring only a single slice per ID bit by using 1-bit ID cells formed as hard-macros. An exemplary 128-bit identification generator is implemented on ten Xilinx Spartan-6 FPGA devices. Experimental results show an uniqueness of 48.52%, and reliability of 92.41% over a 25°C to 70°C temperature range and 10% fluctuation in supply voltage.
