5.1-5.1, due on September 30

• There were a couple of things that were hard for me to process in this reading. The first was that I had a hard time following the construction of the S-boxes as well as the subsequent keys. The algorithms presented in the book were confusing to me. The other thing was going about decryption. I understand that we take the inverse action of all the original actions, in reverse order, but I'm not quite clear on how to perform all of the inverse actions.
• I really enjoyed the reading because we had been introduced to this topic, briefly, in class already. It helped me to follow the author through the thought process. Even though its still a little foggy, I was able to follow the reading okay. I am really understanding the arithmetic with bits and am enjoying this process.
