One can easily go back from ciphertext to plaintext, because there is nothing unknown(mixing of key), all the steps (sub byte, shift rows, mix column) are invertable. MixColumn is Linear Step, it can diffuse the small changes to global changes, change in one byte will effect all other bytes too. But its still linear, it will be prone to differential and linear crypt analysis. this mean M( x + k ) = M (x) + M(k). where as in case of sub byte such relation is not true. | |
