While this confirms the method of production it doesn't say anything about their selection, especially since they were, apparently, generated over a period of months. Specifically you cannot see those candidates that were generated and discarded.

"It is still conceivable that these curves were selected to have a specific property in principle by searching over timestamps to the random number generator."

Yes.

"However, you would only need to do that if you were going to disclose the timestamp as some evidence that the seed was innocuously generated."

Does not logically follow when "doing and saying nothing" will completely suffice.

Well, at least now we have a way to perform that analysis! Generate a bunch of curves by varying (along any degree of freedom) the input parameters to the seed generating function and see if there's any difference between the curves that are generated.

God bless you for keeping this alive.

It doesn't prove anything about the core part of the suspicion, which is they were selected using some undisclosed criteria, which may make them weaker or stronger than some other random numbers.

You are entirely familiar with the precedent of the DES s boxes of course, where that is exactly what happened.

“In under half an hour, Claude discovered the origins of the NIST P-192, P-224, P-256, P-384 and P-521 seeds. None of them were the results of any hash algorithm at all, but rather the output of the C library’s lrand48 random-number generator, seeded with a Unix timestamp!”

Gorgeous. I wonder if the NSA employee who did this suffered a head injury or has been quietly giggling to themselves for the last quarter century.

The two people were Bob Reiter and Jerry Solinas. Jerry wrote in a 2015 email to Daniel Bernstein that he thought it was a hash of the passphrase. I corroborated that story with 4 people, including two ex-NSA folks off the record.

Everyone was wrong!

I wasn't able to reach Bob. He was working in private industry as of 2018, but never responded.

The simplest explanation would be that it was generated the same way as the others, but somebody mistyped a digit somewhere along the way to publishing, and therefore a solution could not be found with the assumption that the number is correct.

Probably not quite this given the timestamps span over almost a year (but have some clustering in August 1997).

Given that the spread suggests they weren't just now() timestamps it would actually be interesting to know what the significance of the timestamps is, if any. Though it could be something boring like randomly sampling some local file creation times.

I think they legitimately did not know. The person who worked on it directly, Jerry Solinas, did not remember and gave an explanation that turned out to be wrong. In his defense, multiple people told the same story about hashing a phrase that was wrong.

Anthropic wants to IPO, they don't want another Fable shutdown situation.

To be clear I would prefer the cyber safeguards to be less restrictive, I think they're currently too much. I often go to open models because of it. But there are likelier reasons to restrict cyber than world domination.

Why are we celebrating and encouraging the walling off of the global intellectual columns?

The idea that you can't reverse engineer things, make things, learn about biology or physics without permission is strange to me. These machines have been trained on the sum intellectual output of humanity, the global intellectual commons, and are being used to close off that commons?

I would be OK with their right to create such restrictions if they weren't lobbying the Government to restrict others, thereby ensuring that they control humanity's intellectual commons well into the future.

Who are they to say what I can learn or can't learn? Who are they to control what I can or can't do with these tools?

Perhaps I'm naive, but I think it's better for humans and the machines if we can all think, learn and build. But then again, I'm the kind of person who rejects the doomer pill.

The risk/reward is way lopsided towards risk for the labs to vet individuals. Much easier to get an organization and have them take the blast if someone/something goes off the rails.

I find it so ridiculous that they (seemingly) forcefully try to state references to dedicated researchers who devoted much of their lives to the problem, while the LLM does not even know which trained papers were effectively used. That means likely many researchers not listed were heavily influencing this achievement, and Claude does not even know that they helped. And the world doesn't know.

howunfortunate 2 hours ago

This happens in academia all the time. You read a ton of papers, chat with tons of people about tons of ideas.

Later you come up some idea, you do the experiment, write the paper, search for relevant citations when you write the intro.

Honestly I think this is actually desirable. For a mind to work well and do things creatively and efficiently it can't be a simple search engine, it needs to blend and meld and reform the information.

And that means the output can't be cleanly deterministically linked to the input. Unless you just keep a log then cite everything you've ever read in your life (and all the conversations and talks too).

On the face if it, the big leap here was Claude autonomously envisioning, and deciding to pursue, the "ancient prng + date" angle - - rather than working backwards from the premise of deliberately weakened seeds or some other popular theory. To me that shows creativity, and modelling of the situation and method of the people at the NSA.

So two questions:

1. TFA mentions the "humourous phrase hash" theory, but Claude's trajectory seems to be a long way from that. To what extent was Claude prompted in the ultimately successful direction?

2. Whats with all the "hmm..." in the internal reasoning process log? Do models really do that? And if so, why? Some weird emergent language thing, or just mimicry?

Assuming that is actually the real reasoning trace (open weight model reasoning traces usually do things like switch languages or talk in non-standard English because of model drift, so it's a bit surprising that Claude wouldn't do the same) there was a study a few years ago that found base models produce better answers if you put "take a deep breath" in the prompt[1]. Maybe in the RL training stage stuff like that gets reinforced and because reasoning traces are hidden in RLHF it doesn't get selected out? My money is on it not being the real reasoning trace though.

On September 20th a friend told me that he had as significant number of Anthropic credits that were about to expire and wondered about a use for them. I do not use their products because of their relentless commitment to depriving the public access to artificial intelligence (and particularly any AI that isn't acting on their behalf) and I strongly discourage anyone else from doing so. But since he was going to use the credits for something, I tried to think of a skut work task that would be of only idle curiosity and would not help advance misanthropic's capability, enable a meaningful public announcement* for them, and was likely already probed by many others (so success would only be lottery effects). -- and basically just something so pointless I wouldn't want to waste my own compute grinding on it but might like to see the result.

So I recommended determining the origins of ECC seeds and base points. The agent worked continuously for many hours and did not uncover anything interesting that wasn't already known. I looked at the transcript and was struck by how idiotic the agent was-- significantly below the standard of intelligence I've come to expect from GLM running locally.

I'm not saying this to suggest that misanthropic hijacked someone elses work yet again-- this is an obvious question that many people have surely posed and success presumably depended on expert use (which was absolutely not applied in my friends example). But it does make me wonder if the company invisibly degraded the model performance.

The process to generate these was opaque, so there was some concern that the values might have been backdoored somehow like Dual_EC_DRBG was; we didn't even have confidence that they were generated from a PRNG rather than some other process. Knowing that the values were generated this way makes it much less plausible that there is such a backdoor.

But you can still analyse the behaviour of the values to identify backdoor behaviour rather than insisting on uncovering the exact method od generation.

As unsurprised as I am by this, and as much as I suspect a lot of people could have guessed it, having Claude confirm it is still fascinating, but.

Somehow, I find these results fascinating, but also quite sad, because we used a machine to solve it at all. I feel like some half drunk motivated graduate level humans could have figured it out too.

Then again, once you know the answer, perhaps you have an obligation to share it, keeping it to yourself might be unfair to everyone else.

Honestly I’m not entirely sure how I feel about all this. I would gladly welcome any groundbreaking work Claude might do to solve hard problems and move the world forward by decades or even centuries.

But these sorts of fun problems feel like things we should avoid pointing LLMs at. They remind me of those weird programming puzzles that are difficult to solve but incredibly fun to work through.

My concern is that if Claude ends up solving all the fun problems, will humans be left with nothing but the hard, headache-inducing ones? Tao had raised a similar concern, problems that graduate students would have been expected to solve and learn the process, are now things you can simply point an LLM at.

I’m still not sure how I will ever reconcile with this feeling, about any of this. I just find it genuinely sad that we might be automating away not only the difficult work, but also the joy of figuring things out for ourselves.

Really? Nobody is concerned about the NSA just cheerfully dictating that? Smells very rainbow-table-y

Uh… did you talk to any cryptographers? This is EXACTLY what a weak curve would look like. Imagine that 1 in a thousand, or one in a million keys, selected at random, are vulnerable to some withheld attack. This approach lets you vary the timestamp or number of iterations until a weak key is found, then have plausible deniability afterward. This is why modern systems choose constants in a way with no free choice of parameters (e.g. sqrt of 2 for first constant, cube root for second constant, etc.).

They even note later in the article that viable curves in the generator sequence seem to have been skipped.

Yes. I did speak to a cryptographer.

This is discussed in the post - since the NSA never mentioned how these seeds were created, it seems unlikely that they would develop a cover story that would not be shared and only opened to scrutiny many years later
