Because of what we covered in class I already felt like I had at least a little bit of a handle on the general idea of the AES algorithm. The 4 layers that make up a round anyways. However the part of this that didn't quite click was talking about the key shedule, about what it means when i is not a multiple of 4, or when it is, what the different steps to take are.
Also my question is, how is something like this implemented? how would the decryptor receive the 10 keys that they will need to use to be able to decrypt. also do they send inverses with the keys or do both ends get to do all of the calculations? or are those tables the same for every single AES encryption?
