sram-based physical unclonable functions (sram pufs) derive
a device dependent secret from the start-up pattern of
their memory cells and have shown very promising results in
previous publications. This work presents a dataset measured
on 144 Infineon XMC4500 microcontrollers containing
160 KiB of sram sampled 101 times each in 2015 and 2016.
Analyses are done using state-of-the-art metrics by Maiti
et al., Hori et al., and by custom inspections. In extensive
comparison to previous work, this work is found to score
best in average Reliability and Bit-Alias, match with previous
top results in average Uniformity and still mid-range
in Uniqueness. This confirms previous results that general
purpose sram on microcontrollers is adequate for most puf
applications. To support further research into sram pufs
and their post-processing, the full dataset originating from
this work will be made publicly available on the internet.
