Re: VMs: Further investigatio of folio f1r

One interesting thing: while there are meny methods published for solving the substitution ciphers, there are only few for transposition ciphers and ac tually quite cumbersome ( see Lanaki lectures on Net On the other hand). Stuill, those are the most underestimated ciphers and in complex form very difficult to solve (especially if we do not know the language).
I still think that almost any transposition cipher
would increase rather decrease the second order entropy
from that of the source text. It also would break up
any underlying digraphs, etc. Most transposition
ciphers I've seen also break up word divisions.
(On the other hand, most transposition ciphers are
easy to solve for short message and hard to solve for
longer ones, if they operate on the whold message.)
