A long, long time ago, we took some benchmarks for Kyber on STM32 NUCLEO-F446ZE. Back then, it was the NIST Submission of Kyber, and we were using the implementation from PQM4 as integration in wolfCrypt. Now, Kyber has evolved into ML-KEM, and we have our implementation! We decided to take some benchmarks on a newer […]
