I am in Rosenow, Rosenow.
From the article: After trying many different approaches, GPT–6
Astra focused on using the repeated place name
ROSENOW ROSENOW as a crib.
This feels extremely underexplained! Why would Astra think to use that as a "crib"? Was it common to repeat the place name in these messages?(Is it possible that this is a misreported detail? It feels like a singular ROSENOW would be an equally effective crib)
> it suspected that the plaintext of Nr. 173, SIPVX, might be related to the plaintext of the unbroken MVUEH message
It makes sense that Nr. 172 and Nr. 173 might be related since they were sent at around the same time.
In Nr. 173, "ROSENOW ROSENOW" was also present.
It also makes sense that a longer crib would generally be more effective than a shorter one.
A sibling commenter explained it - Rosenow is both a municipal name and a district name, so naturally it would be repeated. (Like "New York, New York")
It also makes sense that a longer crib
would generally be more effective than a
shorter one.
It would seem to me that the odds of looking for even a single ROSENOW in the decrypted message would be plenty. The odds of a single ROSENOW randomly occurring in incorrectly decrypted output are vanishingly small. So it seems to me that looking for ROSENOW is a safer bet vs. looking for ROSENOW ROSENOW -- a single ROSENOW is a great sign you've got the correct key, whereas looking for ROSENOW ROSENOW seems like it would deliver false negatives (think of all the times we say "New York" rather than "New York, New York")I'm a novice at crypto though, so, maybe I've got that totally wrong.
I ONLY know this because https://www.youtube.com/watch?v=JsBZOcqZerk, btw.

ICRVSORMCCWQTATYEVFXDBZGGSNXWLPSYWZYTCBSWULRTBZCVGODVJUSLSOOMJQJZSXSEBZPEYMDNXJYTCBreaking enigma is often about using lucky or educated guesses to heuristically reject large chunks of keyspace to leave the remaining keyspace computationally tractable.
Note that the key (lol) complication with this message seems to be that it had a wheel rollover that most messages do not have to deal with, and that rollover drastically reduces how much you can reduce the potential keyspace using all the techniques noticed by the original crackers.
The wheel rollover I think just requires more brute force. Unfortunately, this might be an example of OpenAI the company having vastly more compute time and effort than your average enigma nerd. For example, modern compute clusters like supercomputers can tractably brute force enigma with no cleverness in like a day or less, while home computers would still take thousands of years to compute that. It's very scalable. Did astra have access to significant compute?
However, even considering that, the inferences made by the LLM are good, and picking this specific message to attack, precisely because it should be soluble but might have had an extra wheel rollover that made it more computationally intractable for hobbyists but not a large company is a clever thing to do for the LLM.
I don't think this applies, isn't this just the researcher using ChatGPT Codex on their machine?
It seems like a lot of the recent "breakthroughs" come down to this: spending millions of dollars in compute to solve problems that essentially amount to recreational math problems
The SS-Totenkopf Division was advancing east during the opening weeks of Operation Barbarossa, the German invasion of the Soviet Union. 10 July 1941, the division had just fought its way through the Soviet border defenses around Sebezh. It had moved through Lithuania and Latvia, crossed the Dvina area, and advanced through Dagda toward a place German records called "Rosenow." The division moved out of the Rosenow area around 6 July, fought around Sebezh on 8-9 July, and then continued east/northeast toward Opochka and eventually Porkhov.Were operators of enigma machines aware enough of cryptology or the weaknesses of enigma, for that to have been done intentionally to prevent decryption? I doubt it, otherwise _many_ things should have been done _much_ differently by the operators.
(apologies for my broken learner German, I decided not to use a translator).
Aktuell means current. Not sure if a exact german translation exist for that word. Tatsächlich maybe
