At >400 operations per second, that doesn't explain most of the 2/second (500ms) operations the discoverer apparently observed. Were they running on an old Pi and you on a currently high-end CPU or so? Basically, what hardware is this benchmark on?

I mean it highly depends on the CPU so I only posted it to show the relative slowdown compared to ECDSA. I ran this on my free tier Google Cloud server so it is not some super CPU.

However yes, even on this, not so powerful CPU, it doesnt take 500ms so I dont think it explains it.

Thanks! That indeed sounds like it rules this out as the reason why it was found.

Curious that asymmetric crypto isn't even the slow part here. Feels like they just messed up somewhere (but I don't have the low-level asm/C skills to check that without considerable time investment)
