Abstract
Kriptografija je znanstvena disciplina koja se bavi proučavanjem metoda za slanje poruka u obliku u kojem ih može razumijeti samo osoba kojoj su te poruke namijenjene. Kriptosustavi s javnim ključem imaju javan ključ za šifriranje poruke, ali tajan ključ za njezino dešifriranje. Koriste se za prijenos ključeva modernih simetričnih kriptosustava i u digitalnim potpisima. Neki od njih temelje se na problemu faktorizacije velikih prirodnih brojeva. U radu su objašnjeni RSA i Rabinov kriptosustav. RSA kriptosustav svoju sigurnost zasniva na problemu faktorizacije, a Rabinov kriptosustav na problemu kvadratnog korijena po složenom modulu koji je ekvivalentan problemu faktorizacije tog modula. Kriptoanaliza oba kriptosustava ističe njihove slabosti, ali time i mogućnosti te potrebne promjene za sprječavanje poznatih napada i jačanje njihove sigurnosti.
Abstract (english)
Cryptography is a scientific discipline that studies methods for sending messages in a form in which they can only be understood by the person to whom they are intended. Public key cryptosystems have a public key to encrypt the message, but a private key to decrypt it. They are used to transfer the keys of modern symmetric cryptosystems and in digital signatures. Some of them are based on the problem factorization of positive integers. The paper explains RSA and Rabin’s cryptosystem. The RSA cryptosystem bases its security on the factorization problem while the Rabin cryptosystem on the square root of the composite modulus problem that is equivalent to the factorization problem of that modulus. Cryptanalysis of both cryptosystems emphasizes their weaknesses, but also possibilities and necessary changes to prevent known attacks and strengthen their security.
