Abstract
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.
