摘　　要：基于现场可编程门阵列(Field Programmable Gate Array,FPGA)的物理不可克隆函数(Physically Unclonable Functions,PUF)技术的基本原理和优缺点,分析FPGA PUF技术输出特征值原理和特性,针对基于环形振荡器的物理不可克隆函数(Ring Oscillator Based Physically Unclonable Functions,RO-PUF)输出响应存在噪声的特性,引入特征池、哈希算法等技术,在赛灵思K7-325T FPGA上实现了随机数发生器。并对实现平台在不同环境温度下进行随机性测试。实验结果表明,该FPGA PUF技术的随机数产生技术可以产生高质量的随机数序列,可以满足部分密码应用场景对随机数的需求。Based on the basic principles as well as the advantages of FPGA(Field Programmable Gate Array)-based PUF(Physical Unclonable Function)technology,this paper analyzes the principle and characteristics of FPGA-based PUF technology and introduces feature pool,hash algorithm and other technologies for the property of noise in the output response of a RO-PUF(Ring Oscillator-PUF).It implements a random number generator on a Xilinx K7-325T FPGA and testes the randomness of the implementation platform at different environmental temperatures.The experimental results indicate that the FPGA-based PUF technology can generate high-quality random number sequences and can meet the random number requirements in some cryptographic application scenarios.
