Abstract
Cilj ovoga rada je upoznavanje s osnovama kriptografskih sustava s javnim ključem. Od povijesne perspektive pa do prvih formalnih definicija koje su postavile temelje nove grane znanosti. Kroz primjere vidjeti ćemo takvu komunikaciju iz tri različite perspektive: pošiljaoca, primatelja i ”protivnika”. Početi ćemo sa Diffie-Hellmanovim protokolom za razmjenu ključeva, jer je ono postavilo temelje moderne kriptografije. Zatim ćemo objasniti prvi službeni kriptosustav pod nazivom ElGamalov kriptosustav. Nakon toga baviti ćemo se analizom kompleksnosti matematičkih problema koji se kriju u pozadini obradenih kriptosustava. Dodatno spomenuti ćemo kako odabrati javne ključeve na način da sustav bude što sigurniji.
Abstract (english)
The aim of this paper is getting to know the basics of public key cryptography. We will start with the history of it, and work our way through the formal definitions that laid the foundations of this new branch of science Through examples we will see communication from three different perspectives: sender, receiver and the ”enemy”. We will start off with the Diffie-Hellman key exchange, because it is one of the most important principles in public key cryptography. Later on, we will learn about the first formal cryptosystem called ElGamalov cryptosystem. On the end, we will analyse the time complexity of the underlaying math problems of mentioned cryptosystems. Additionaly, we will see how public keys should be picked to make the cryptosystem as safe as possible.
