Richard Bean, 2021. Proceedings of the 4th International Conference on Historical Cryptology (HistoCrypt 2021), Linköping Electronic Conference Proceedings 183: 25-33.
Monte Carlo permutation tests on the K4 ciphertext and the released plaintext find strong evidence of a one-to-one relation between corresponding letters; proposes the Gromark cipher as a system that would explain most or all of the observed properties.
What it's used for here
