The winner of the Best Paper Award at Crypto this year was a significant improvement to lattice-based cryptanalysis.

This is important, because a bunch of NIST’s post-quantum options base their security on lattice problems.

I worry about standardizing on post-quantum algorithms too quickly. We are still learning a lot about the security of these systems, and this paper is an example of that learning.

News story.
