- An AI system decrypted a cipher written in 1809 by Napoleon’s nephew, marking another instance of AI advancing cryptanalysis.
- The cipher’s decryption was described as achievable by a patient specialist since at least 1970, suggesting the AI’s role was primarily one of speed rather than fundamental breakthrough.
- The announcement was shared via a social media post linking to a detailed write-up of the decryption process.
A cipher written in 1809 by Napoleon’s nephew has been decrypted with the assistance of an AI system, according to a report published on Schneier on Security. The decryption was highlighted as an example of AI accelerating a task that a patient specialist could have accomplished since at least 1970, emphasizing speed over a fundamental breakthrough in cryptanalysis.
The announcement of the decryption was shared via a social media post, linking to a detailed write-up that includes a section discussing the historical and technical context of the cipher. The write-up notes that while the decryption was technically feasible for a human expert, the AI system enabled a significantly faster resolution.
The cipher in question is part of a historical correspondence from 1809, and its decryption was framed as another instance of AI systems demonstrating capability in tasks traditionally requiring specialized human expertise.
