A long text (75,000 characters), a known cipher type (homophonic substitution) and a natural language that a language model could identify made statistical decipherment possible.
Where it stands
Most likelyIts tests supported it: two pieces of evidence for, none against. It needs two reviews to be accepted.
What it predicts
- The same method succeeds on other long homophonic ciphers in known languages.
- It fails on short texts, on codes that substitute for words, and on texts in no known language.
What would rule it out
- The method succeeds on a short text or a word-code, or fails on a comparable long homophonic cipher.
