# Deciphering Historical Syllabic Ciphers

George Lasry, 2024. _Proceedings of the 7th International Conference on Historical Cryptology (HistoCrypt 2024)_ 53.

Presents a computer method that recovers much of the key to historical ciphers containing syllable signs, leaving the rest for manual work, and uses it to solve several French, Spanish and Italian ciphers.

## What it's used for here

The book (chapter 30) adopts its method after letter-by-letter scoring failed on planted keys, and the mixed-keys survey takes syllable-sign counts and its vocabulary-element annealing from it.
