The mono-alphabetical substituted cipher is a cipher where one-to-one mapping is used to substitute each of the characters of the plaintext by a corresponding character of the ciphertext. One of the possibility, how solve the mono-alphabetical substituted text is frequency analysis of the single letters and frequency analysis of the bigrams of the ciphertext. The paper presents algorithm for automatic deciphering of the mono-alphabetical substituted ciphertext. Computer simulation model of the algorithm is realized in MS Excel Spreadsheet. The computer simulation enables deciphering of ciphertext of different languages.
