摘　　要：介绍了基于树莓派B+硬件平台实现DRAM PUF密钥发生系统的研究与设计。系统从嵌入式设备广泛使用的动态随机存储器中提取带有自身硬件指纹的物理不可克隆函数,通过模糊提取算法和Hash算法消除由于环境噪声及老化效应带来的错误信息,稳定生成128位DRAM PUF安全密钥。该系统生成的DRAM PUF安全密钥可靠性高达99%,唯一性为48.44%,均匀性为50%,并且密钥的信息熵值为1.0。The research and design of a DRAM PUF key generation system based on the Raspberry Pi B+hardware platform are introduced.The system extracts the physical unclonable function with its own hardware fingerprint from the dynamic random memory widely used in embedded devices,and achieves stable generation of 128-bit DRAM PUF security keys through fuzzy extraction algorithm and Hash algorithm to eliminate the error information due to environmental noise and aging effect.The system generates DRAM PUF security keys with 99%reliability,48.44%uniqueness,50%uniformity,and the information entropy value of the key is 1.0.
