I know that in AES, in encryption stage, in MixColumns, we use [4x4] coefficient matrix with values having only (00,01,02,03). Does anyone know what values are used for coefficient matrix in InvMixColumns at decryption stage? I know those coefficients occur by taking inverse of 00,01,02,03 in rajindel field. I calculated those as I know that in AES, in encryption stage, in Mix
