KYBER-Level1 Benchmarks on STM32

Further to our previous announcement about bringing post-quantum KEMs in TLS 1.3 on STM32, we have also brought PQM4’s KYBER Level1 KEM into our benchmarking infrastructure. Note that we do not build PQM4 with optimizations as a bug fix is soon to come for optimization flags. You can monitor the progress of the issue here.

Once that is fixed, we’ll re-post our results on this blog. We run the benchmarks together with conventional algorithms so you can compare the results. Please see below:
