Classical ciphers can often be broken using some statistical\ninformation about the plaintext, that means the frequency analysis. After the discovery\nof frequency analysis, perhaps by the Arab mathematician Al-Kindi in the 9th century,\nmost all such ciphers became breakable, until the development of the polyalphabetic\nciphers. These ciphers was done most possible by Leon Battista Alberti around the year\n1467. The polyalphabetic ciphers used different ciphers for various parts of a message.\nThe most famous polyalphabetic ciphers is the Vigenère cipher. In this paper, the idea\nto improve this cipher arises from the Vernam idea specified in U.S. Patent 1,310,719,\nissued July 22, 1919, in which he used the XOR operation to encode the characters in\nthe Baudot code, a 5-bit code, invented by Émile Baudot in 1870, which allowed the\ntelegraph transmission.
