It takes more than 630 gates to implement it with repetitive multiplications in GF (28). So, to reduce the gate count in large amount, composite field arithmetic is used.

The inverse S-box is simply the S-box run in reverse. For example, the inverse S-box of 0xdb is 0x9f. It is calculated by first calculating the inverse affine transformation of the input value, followed by the multiplicative inverse. The inverse affine transformation is as follows: The following table represents Rijndael's ... WebCreate a separate verilog file for you sbox.
