Analysis of SRAM-Based PUFs on AMD Xilinx UltraScale+ FPGAs IEEE CNS 25 Poster

Physically Unclonable Functions (PUFs) have proven to be a strong and promising foundation for hardware-based authentication and key derivation. Especially SRAM-based PUFs are an obvious choice for any device with SRAM, such as Field Programmable Gate Arrays (FPGAs). This work ported an SRAM-based PUF implementation method to AMD Xilinx UltraScale+ FPGAs. Start-up values of several devices were extracted and analyzed. The results show recurring patterns in the start-up values which questions their suitability for secure SRAM-based PUFs. Further inspection of the patterns origins were done.
