Rijndael Mix Columns
The MixColumns operation performed by the Rijndael cipher, along with the shift-rows step, is the primary source of diffusion in Rijndael. Each column is treated as a polynomial over GF(28) and is then multiplied modulo with a fixed polynomial ; the inverse of this polynomial is .
