Maximum Distance Separable (MDS) and Maximum Distance Binary Linear (MDBL) codes are used as diffusion layers in the design of the well-known block ciphers like the Advanced Encryption Standard, Khazad, Camellia, and ARIA. The reason for the use of these codes in the design of block ciphers is that they provide optimal diffusion effect to meet security of a(More)
AES block cipher includes a linear transformation called MixColumns which transforms 32-bit input to 32-bit output. This transformation has the property that makes linear and differential attacks harder. In this study, we obtain a model of MixColumns transformation in bits. In fact, there are two reasons for obtaining this model. The first one is to show(More)
