Abstract
U ovom diplomskom radu opisana je temeljna ideja diferencijalne kriptoanalize na općenitom primjeru. Implementirana je jednostavna, proizvoljna, 4-bitna šifra sa dvije runde, jednom S-kutijom u svakoj rundu, te jednim potključem u svakoj rundi. Za ovu šifru provedena je potrebna analiza koju zahtijeva diferencijalna kriptoanaliza, a uključuje analizu karakteristike šifre do R-1 rundi i analizu frekvencija ulaza i izlaza šifre za karakteristiku do R-1 rundi. Nakon obavljene analize implementiran... More je napad kojeg opisuje diferencijalna kriptoanaliza na 4-bitnu šifru. Potključevi su uspješno dohvaćeni, a nad S-kutijom su provedeni daljnji testovi kako bi se uočio utjecaj konfiguracije S-kutije na ulazno-izlazne odnose. Sav programski kod realiziran je u python programskom jeziku. Less
Abstract (english)
The fundamental idea of differential cryptanalysis is described in this thesis on a general example. A simple, arbitrary, 4-bit cipher has been implemented. This cipher consists of two rounds, one S-box in each round, and one subkey in each round. Necessary analysis dictated by differential cryptanalysis has been conducted for this 4-bit cipher, which includes analysing cipher characteristic to R-1 rounds and analysing input and output frequencies for cipher's R-1 round characteristic. After... More analysis, differential cryptanalysis attack on the 4-bit cipher has been implemented. Subkeys were successfully retrieved, and further analyses of S-boxes have been conducted to test out the S-box configuration influence on the input and output relations. All code was implemented using python programming language. Less
