Abstract

Magistrsko delo obravnava kriptoanalizo Vigènerove šifre z algoritmom diferencialne evolucije in algoritmom kresnic, ki se uvrščata med algoritme po vzorih iz narave. V magistrskem delu opisujemo kriptoanalizo, Vigènerovo šifro, algoritme po vzorih iz narave ter metodo za kriptoanalizo, ki smo jo predlagali v magistrskem delu. Ugotovili smo, da sta algoritem diferencialne evolucije in algoritem kresnic primerna za kriptoanalizo Vigenèrove šifre. Rezultati so pokazali, da je algoritem diferencialne evolucije uspešnejši od algoritma kresnic. Ugotovili smo tudi, da se uspešnost kriptoanalize zmanjšuje z večanjem dolžine ključa.

Secondary abstract: Master's thesis deals with cryptanalysis of Vigenère cipher using differential evolution algorithm and firefly algorithm, both belonging to nature-inspired algorithms. In the master's thesis, we describe what cryptoanalysis is, Vigenère cipher, nature-inspired algorithms, and a method we proposed in the thesis. We found out that the differential evolution algorithm and firefly algorithm are suitable for the cryptanalysis of Vigenère cipher. Results showed that the differential evolution algorithm is more successful than the firefly algorithm. We found out also that cryptanalysis success decreases with increased key length.
