If you get bored, you can jump to the code. When I was being developed, a clever guy was able to find a shortcut path through 6 rounds. If you look carefully, you’ll see that each bit of a round’s output depends on every bit from two rounds ago. To increase this diffusion avalanche, I added 4 extra rounds. Why bother with all of this math? Encryption deals with bits and bytes, right?

Well, there’s one last connection: a 7th degree polynomial can be represented in exactly 1 byte since the new way uses only 0 or 1 for coefficients. I treat each column as a polynomial. This all simplifies to a matrix multiply. In keeping with the Foot-Shooting Prevention Agreement, it shouldn’t be used for production code, but it should be helpful in seeing exactly where all the numbers came from in this play. The Design of Rijndael is the book on the subject, written by the Rijndael creators.

The FIPS-197 specification formally defines AES and provides a good overview. The Puzzle Palace, especially chapter 9, was helpful while creating Act 1.
