I agree with this. And I think that this is more likely to be the case. But I really think with all that we now know about US governmental organisations the possibility of backdoors or coercion should not be ruled out.
The whole point of the competition structure is that you don't simply have to trust NIST; the competitors (and cryptographers who aren't even entrants in the contest) are peer reviewing each other, and NIST is refereeing.
What Bernstein is counting on here is that his cheering section doesn't know the names of any cryptographers besides "djb", Bruce Schneier, and maybe, just maybe, Joan Daemen. If they knew anything about who the PQC team members were, they'd shoot milk out their nose at the suggestion that NSA had suborned backdoors from them. What's upsetting is that he knows this, and he knows you don't know this, and he's exploiting that.
May I ask what you view as the alternative? (No formal cryptographic standard, or something else?)
Likely scenarios, and that closed review hides:
- Peer review happened... But was lame. Surprisingly common, and often the typical case.
- If some discussion did come up on a likely attack... What? Was the rebuttal and final discussion satisfactory?
It's interesting if some gov team found additional things... But I'm less worried about that, they're effectively just an 'extra' review committee. Though as djb fears, a no-no if they ask to weaken something... And hence another reason it's good for the history of the alg to be public.
Edit: Now that storage and video are cheap, I can easily imagine a shift to requiring all emails + meetings to be fully published.
Edit: I can't reply some reason, but having been an academic reviewer, including for security, and won awards for best of year/decade academic papers, I can say academic peer review may not be doing what most people think, eg, it is often more about novelty and trends and increments from a 1 hour skim. Or catching only super obvious things outsiders and fresh researchers mess up on. Very diff from say a yearlong $1M dedicated pentest. Which I doubt happened. It's easy to tell which kind of review happened when reading a report... Hence me liking a call for openness here.
Replying to your edit I've been an academic peer reviewer too. For all of its weaknesses, that kind of peer review is the premise of the PQC contest --- indeed, it's the premise of pretty much all of modern cryptography.
In this case, looks like the community does value backing up its claims, and the protocol is verified: https://www.wireguard.com/formal-verification/ . Pretty awesome! The implementation itself seems to be written unsafely, so TBD there.
If it's worth anything, you have changed my opinion on this. You raise very good points.
I spent almost 2 decades as a Daniel Bernstein ultra-fan --- he's a hometown hero, and also someone whose work was extremely important to me professionally in the 1990s, and, to me at least, he has always been kind and cheerful; he even tried to give us some ideas for ECC challenges for Cryptopals. I know what it's like to be in the situation of (a) deeply admiring Bernstein and (b) only really paying attention to one cryptographer in the world (Bernstein).
But talk to a bunch of other cryptographers --- and, also, learn about the work a lot of other cryptographers are doing --- and you're going to hear stories. I'm not going to say Bernstein has a bad reputation; for one thing, I'm not qualified to say that, and for another I don't think "bad" is the right word. So I'll put it this way: Bernstein has a fucked up reputation in his field. I am not at all happy to say that, but it's true.
He has never been that to me; I've had just a few personal interactions with him, and they've been uniformly positive. My feeling is that he was generous with his time and expertise when I had questions, and pleasant and welcoming in person.
He has, in the intervening years, done several things that grossed me the fuck out, though. There are certainly people who revel in hating the guy. I'm not one of them.
Please point to this suggestion.
