Special types of high nonlinear functions (APN functions) defined over finite fields of characteristic 2 have important applications in cryptography. The design of block ciphers by using APN functions provides high resistance against differential attacks. The goal of this paper is to supply a comprehensive review of the most important facts connecting differential attacks, DES-like ciphers and APN functions. In this paper, we show how differential attacks work against DES-like ciphers and how APN functions work against differential attacks.
