Manuscrito de Voynich - Análisis del algoritmo de codificación con los métodos de cifrado conocidos en la época medieval y resultados de las marginalias que no fueron encriptadas

Abstract

In the present study I describe and analyze two objectives, the first is about opposition and equivalence of the Voynich manuscript coding algorithm with the known in medieval period methods of ciphering. According to the results of my innovative research of the Voynich manuscript was written in medieval Galician (Galician-Portuguese). Its coding algorithm was influenced by the substitution cipher of using a polyalphabetic cipher for the most part of its text, as well as it was definitely influenced by transposition cipher for double ciphered alchemical text. However, it should be mentioned that there are significant differences between the codes that were used in the medieval period and the encoded algorithm of the Voynich manuscript. For the reason that made deciphering more complicated over the centuries, substitution encryption of a polyalphabetic cipher was used partly and simultaneusly with monoalphabetic cipher in addition to uncoded text at all. Therefore the main thing to take into consideration is that the second objective of the most interest in this particular article are parts of the Voynich manuscript texts – marginalies– that were not encrypted at all and their reading.
