Overview

This archive contains the following

• simulation contains the simulation scripts used in Section 4 of the paper. If you have Python3 installed, then these should allow you to reproduce the results in the paper. For more details see simulation/README.md

• attack contains the attack scripts used in Section 5 of the paper. If you have a ChipWhisperer-Lite (CW1173) 32-bit basic board which features a STM32F303 (and a little bit of time), you can reproduce the results presented in the paper by simply running our attack script.
  For more details see attack/README.md

• benchmark contains our implementation with and without countermeasures together with a benchmarking framework which allows to reproduce the results of Section 7 of the paper. In addition to the STM32F303, it also supports the popular STM32F407.
  For more details see benchmark/README.md
