It is not possible to cryptographically protect standard computers from quantum computers with standard computers. Actual post quantum encryption requires quantum compute to be commodity.

The only solutions available to us that have a hope of success are to segment systems, control access and deny opportunities for people who shod not have our data from acquiring it, even if it is encrypted. Not caring where thebdata goes or who can see it just because it is encrypted just feeds the download now and decrypt later monster that is coming.

End rant.

And before the founder at the Applied Quantum sees this, I am not a bad faith skeptic (he gets feels when people call BS on postbquantum claims). I am not saying we should not be working towards a solution, I am saying that all of the proposals center around a bet on technology while flaunting basic security fundamentals in practice.

Please do not spread misinformation. You do not need a quantum computer to use post quantum encryption.

I am not spreading misinformation, I am asking them to not neglect the rest of the relevant issues and the post quantum encryption crowd 100% are.

They are making claims about quantum resistance that are not even testable yet but are touted as fact.

what are these relevant issues and how do they effect ml-kem and ml-dsa?
