Quote:One thing we’ve just started working on is exploring what type of encipherment methods give the sort of odd character distributions — the low h2 — we see in Voynichese. We have a corpus of text from Wikipedia and an ancient language corpus of digitized materials from medieval and historical texts, and we can apply different cipher methods to these texts and see if the result matches the statistical properties of Voynichese.
I would have been interested to know which encryption methods could be considered. Newer methods would have to be excluded in principle, and the possibilities for methods at the beginning of the 15th century are quite limited.
