hi,
Can anyone help me regarding how the AES constant for a specific
polynomial is chosen.
For the polynomial represented by 0x11b, why is 0x63 a good number. (S
Box step)
Is there any formula, or tutorial I can look for.
I would like to know the constants for the other polynomials.

Thanks.
regards,
Amol.
