Abstract
U ovom radu započinjemo proučavanje moderne kriptografije uvođenjem pojma računalne sigurnosti. Zatim definiramo računalno sigurnu enkripciju te konstruiramo sigurne sheme enkripcije s tajnim ključem uvođenjem pojma protočnih šifri i pojma pseudoslučajnosti koji obuhvaća ideju da nešto može "izgledati" potpuno slučajno iako to nije. Ovaj moćni koncept leži u osnovi većeg dijela moderne kriptografije, a ima primjene i implikacije i u mnogim drugim područjima. Za kraj, proučavamo neke jače sigurnosne ideje koje obuhvaćaju napade odabranog otvorenog teksta i CPA-sigurnost te pokazujemo prednosti njihovog korištenja.
Abstract (english)
In this thesis we begin our study of modern cryptography by introducing the concept of computational security. We then define computationally secure encryption and construct secure private-key encryption schemes by introducing the notion of steam ciphers and the notion of pseudorandomness that encompasses the idea that something can "look" completely random even though it is not. This powerful concept underlies much of modern cryptography and has applications as well as implications in many other areas. Finally, we introduce some stronger security ideas that include attacks on selected plaintext and CPA-security and show the benefits of using them.
