The VMS as a possible chain encryption ( Mod 23 ).

[oshfdk]

It is interesting to see that your approach is also a chain cipher. Extensive mapping avoids the problems that inevitably arise with my approach (entropy, letter distribution, last letter in the previous word, etc.). So I have to conclude that my method does not stand up to scrutiny, although the idea that a simple process could work was very tempting.

My idea of the ideal cipher system for the Voynich MS is something that has the right statistical properties and at the same time is very simple to read and write, ideally allowing one to read off the page with nearly normal reading speed. So, a simple process that could work would be very interesting.
