Introduction It has come to my attention that people are wagering dinner invitations to anyone who can convince me to publicly state my opinions and reasonings on hybrid signatures.

FN-DSA (née Falcon) is a proposed post-quantum signature standard that keeps polarizing engineers.

After publishing my series on UOV, one feedback I got was that my blog posts made people feel more confident in the security of the scheme, because “at least someone is looking into these things”.

What is this?

When I first learned about Diffie-Hellman and especially elliptic curve Diffie-Hellman, I had one rather obvious question: Why elliptic curves?

Last time I had an issue with standardization going into the, in my opinion, wrong direction, I wrote a blog post about it.

In Part I, we looked at the problem we want attackers of UOV to solve.

After Part I looked at the hard problem underlying Unbalanced Oil and Vinegar, it is now finally time to talk about the algorithm itself.

Introduction While there are many schemes discussed in the currently ongoing second onramp for PQC signatures, Unbalanced Oil and Vinegar (UOV) is both one of the most serious contenders and also an extremely curious scheme.

I mentioned ranted about this topic as a section of a previous blog post (at the very end), but the topic keeps coming up, so I am escalating to a full blog post, since obviously that will help with all these people who are wrong on the internet standardi…
