Abstract
U ovom radu bavili smo se supstitucijskim šiframa kao što su monoalfabetske supstitucijske šifre i nekima od nestandardnih supsticijskih šifri. Na samom početku rada naveli smo definicije, teoreme i rezultate iz područja algebre i teorije brojeva koji su nužni za praćenje daljnih rezultata u radu. Definirali smo supstitucijske šifre i na različitim primjerima proveli smo postupak šifriranja i dešifriranja istih. Prikazali smo šifre poput Cezarove i afine šifre, pigpen šifre i Polybiusovog kvadrata. Za svaku od ovih šifri naveli smo različite primjere na kojima smo pokazali postupke šifriranja i dešifriranja po pravilu za svaku navedenu šifru. Na kraju smo rada prikazali šifru koju je koristio serijski ubojica Zodiac,čiji šifrati već nekoliko godina nisu dekriptirani.
Abstract (english)
This paper elaborates on substitution ciphers such as monoalphabetic ciphers and some non-standard substitution ciphers. The paper starts with the definitions, theorems and results in the field of algebra and number theory all of which are essential for the paper scope and results. Upon defining the substitution ciphers, the procedures of ciphering and deciphering are exemplified, namely the Caesar, affine, pigpen and Polybius square ciphers are elaborate on. Each of the ciphers are exemplified and the procedures of ciphering and deciphering illustrated. Finally, the cipher used by the serial murderer Zodiac, whose ciphers have not been deciphered yet, is described.
