I feel that this week's homework assignment was harder than the previous homework assignments, I hope that this was because this is better preparing us for the test (overshooting the difficulty of the test? I hope). I think that key ideas include the basic algorithm for the different methods of encrypting. I think that many of the questions will not be "crack the code" questions, but "how would you start to crack this code" or "what are the strengths and weaknesses of a system that works in this way" .
I need to get a solid grasp on which types of block ciphering are what, ECB, CBC, CTR all still kind of are just letters to me.
I still have to do probllems six and seven on the homework for tomorrow, but it is too late to do them tonight, so I will finish them in the morning.
I think that the hardest part of the last couple of section is how much it seems like memorization instead of problemsolving. But it is still a really enjoyable class. And it is getting more difficult just after other classes midterms, so that is good, much better than while other things are taking my time.
That could be why the class seems harder, I have lessened my studying in this class to focus on each test as it came up. next week should be better in this class because I have a couple of breather days next week.
