Abstract
U ovom radu bavili smo se analizom monoalfabetskih supstitucijskih šifri. Najprije smo naveli definicije i rezultate iz algebre i teorije brojeva što je potrebno kako bi se uspješno pratio sadržaj rada. Definirali smo monoalfabetske supstitucijske šifre te na primjerima pokazali šifriranje i dešifriranje teksta korištenjem raznim tipovima šifri. Naveli smo neke inačice monoalfabetskih šifri kao što su hebrejska, Cezarova, afina, pigpen šifra te Polybiusov kvadrat. Svaku od ovih šifri pokrijepili smo raznim primjerima. Objasnili smo i homofonu supstitucijsku šifru te njene razne inačice. Na kraju rada, spomenuli smo šifru kojom se koristio serijski ubojica Zodiac, čiji šifrati već desetke godina nisu dekriptirani.
Abstract (english)
In this paper, we analized a monoalphabetic substitution ciphers. First of all, we gave defnitions and results from algebra and number theory, usefull fot successfully reading the content of the paper. We defined the monoalphabetic substitution ciphers. Through the different types of examples we illustrated encryption and decryption of plain text. Moreover, we mentioned some versions of the monoalfabetic codes such as Hebrew code, Caesar cipher, Afine cipher, Pigpen code and Polybius square. Each of them is confirmed by various type of examples. Besides that, we explained the homophonic substitution cipher and some of its variants. At the end, we mentioned the code used by the serial killer Zodiac, whose ciphertext has not been decrypted for decades.
