1. The most difficult thing about these sections is the whole process. I think mostly this is because I have the test on my mind. I'm concerned about having to keep all these processes straight. They are so complex! If a computer is required to use them, how can I expect to keep them straight in my head?! Also, the key schedule really threw me for a loop! If you expand a 4x4 matrix by 40 columns, you are going to have a very non-square matrix. I'm confused if this is even the case. I feel like what we are learning is much more Computer Science than Math.
2. My only reflection is in regards to the test. How in the world are we going to be tested on AES, DES, etc?! They are so hard to keep track of and separate in my brain! How can we be expected to commit all this information to memory? This is stuff that is hard to derive, as oppose to most other math classes in which the concepts can be derived from one another. This, however, is literally just a bunch of 1s and 0s in literally an arbitrary pattern (pattern is used very loosely). I feel like my brain is turning to mush just trying to think about keeping it all straight in my head.
