Anyone have any sources describing the use of Hidden Markov Modeling in cryptanalysis? The use of Hidden Markov Modeling, period? |

That second one has details of the actual algorithms that I'd not been able to find. I've been looking at this, particularly chapters 5&6: Speech and Language Processing This is suggestive, as to crypto applications: Hamptonese and Hidden Markov Models And in this, you'll fnd an article: "Solving the Running Key Cipher with the Viterbi Algorithm": Cryptologia - free sample copy |

Wikipedia seems to have clear and concise explanations, in this area: Viterbi algorithm Baum Welch algorithm |
