Abstract

The paper is devoted to frequency analysis of English texts and using methods of the analysis in deciphering mono-alphabetic ciphertexts. The relevance of this study is a huge interest in cryptography in recent years in connection with the emergence of cryptocurrencies and the great need to ensure information security of large amounts of data. The aim of the research is to show the possibilities of frequency cryptanalysis and to demonstrate the result of its methods in decoding the real ciphertext. The methodological base of the paper is the studies of cryptographs and statisticians. The result of the research is collected data on the frequency distribution of letters in the texts of different subjects and conclusions made while decoding of the ciphertext. Particular attention is paid to practical algorithms that can help in deciphering mono-alphabetic ciphers. The article is useful for novice cryptographers and mathematical linguists.
