Shout out to the folks maintaining the pq-code-package repos. I’ve been building their ML-KEM and ML-DSA implementations for CHERIooT and they’ve been an absolute delight to work with. I don’t think I’ve ever had better interactions with a F/OSS project (though I have had a few that were as good).
Don’t worry, I’m not touching any of the crypto code…

The paper I co-authored (“A Critical Analysis of Deployed Use Cases for Quantum Key Distribution and Comparison with Post-Quantum Cryptography”) was accepted for publication by “EPJ Quantum Technology” today. 😊
You can find the preprint here, Nick will eventually update it with the final changes.
In short: We looked into existing use-cases for #QuantumKeyDistribution and whether they make any sense and did so as a joint team between people with a QKD-background and cryptographers who started out very critical of QKD. (I’m firmly in the latter camp.)
My personal summary (though some of my co-authors won’t share it to this extend): #QKD is bullshit and not useful for practical purposes as it stands.

One of the most infuriating things about #QuantumComputing related stuff is that #QuantumComputers being theoretically able to break factoring and DLog (aka: most asymmetric crypto in current use) using Shor’s algorithm is used as a selling point for #QuantumCryptography (QC) or #QuantumKeyDistribution (#QKD).
The two topics really have nothing to do with each other, the solution for dealing with the broken schemes is to replace them with non-broken ones.
If we want QKD, there has to be a DIFFERENT motivation for it, that has nothing to do with Shor’s algorithm.
Somehow we have allowed the presentation to become “after classical crypto choose #PostQuantumCrypto (#PQC) or QKD”, instead of “keep using classical crypto that is secure against known attacks or switch to QKD”.
In line with that we should also increasingly move to stop talking about PQC, and just talk about secure #cryptography, because that is really all it is.
