# Re: VMs: An idea

```You misunderstand what I am attempting to do. The numbers will indicate
where the letters fall in relation to an attempt to decipher using the
cylinder type decipherment. I could have chosen letters but there aren't 128
of them. Call them tokens instead. Strings of numbers 1 to 3 digits long
will stand in place of the assumed letters. These will then be analysed for
entropy and whatever else can be used to see how the values change as
different attempts are made. It would be like having a language in a 128
letter alphabet. It would still show a pattern, though not consistent with
the plaintext language. As each group of values is counted it will either
show which tokens are likely to be vowels or consonants or it would quickly
become apparent that the method is wrong, as the statistics would not form a
normal curve.

If abbreviation is involved as NIck Pelling believes then we are lost anyway
and have to think of a more specific attack method. Also in nulls or even
codebook numbers are involved then the whole method assumes another level of
complexity altogether.

This would need to be done on a variety of transcription methods. I was
recently sent a file by Robert Teague which I am looking into at the moment.
This will form the basis of the attack.
