Abstract
U radu smo opisali funkcije koje zbog svojih svojstava zauzimaju vrlo značajno mjesto u kriptografiji, a to su hash funkcije. U prvom dijelu smo definirali jednosmjernu funkciju, budući da je jednosmjernost bitno svojstvo hash funkcija. Naveli smo svojstva kriptografske hash funkcije, kao i odnose medu njima. Pomoću rođendanskog paradoksa odnosno rođendanskog napada, objasnili smo potrebu za definiranjem minimalne duljine hash vrijednosti. Nakon toga, detaljno je opisana Merkle-D˚amgard... More konstrukcija hash funkcije. Naveli smo primjer koji prati sve korake konstrukcije. Nadalje, opisali smo MD4 hash funkciju, definirali njene korake konstrukcije te raspisali algoritam. Kroz primjer je objašnjena MD4 funkcija i njene specifičnosti. Nakon MD4 funkcije, opisali smo njenu nasljednu MD5 funkciju. Na kraju smo opisali SHA-1 funkciju, njenu konstrukciju te smo naveli primjer hashiranja pomoću SHA-1 funkcije. Opisano je trenutno sigurnosno stanje SHA-1 funkcije i izvršavanje prvog napada kolizijom u praksi. Less
Abstract (english)
In this paper we described functions which takes very important place in cryptography because of their properties, and we call them hash functions. We defined one way function since one-way property is an essential feature of hash functions. We have specified the properties of hash functions as well as relationships between them. With the birthday paradox and the birthday attack we have explained the need to define the minimum length of hash values. After that, the Merkle-D˚amgard... More construction has been described in detail. We have mentioned an example that follows all constuction steps. Furthemore, we described the MD4 has function, indicated its construction steps, and wrote down algorithm. Through the example, MD4 function and its specifics are explained. After the MD4 function, we described its successor, MD5 function. Finally, we described the SHA-1 function, its construction, and we provided an example of the hashing using the SHA-1 function. The current state of the SHA-1 function and te first collision attack in practice are described. Less
