Classic McEliece on the ARM Cortex-M4

June 9, 2021


Chou Tung - Academia Sinica


This paper presents a constant-time implementation of Classic McEliece tailored for stm32f4-Discovery. The implementation follows the 3rd-round specification. There is no data cache on stm32f4-Discovery, but our implementation does not take advantage of this: our implementation does not use secret-dependent memory indices, so it is constant-time even on M4 devices with data caches.
