Sec. 1.1-1.2, 3.1, due Sept 2nd

1. The most difficult part of this reading assignment was just getting used to the language used in cryptography and trying to wrap my brain around it's concepts. For example, when I read about Public key communication, I was kind of confused trying to imagine what they were saying in a real life example, but when they gave us a nonmathematical example, it immediately made sense!
It also took me awhile to understand how they tried to explain the other way that you can find the gcd of two numbers. I don't know if it was just the wording of that paragraph (which is was I think) or what, but it took me a little while and I had to look at the examples. I think I understand it, it probably doesn't matter now, but I think I got it down. I just like the way we did it; using the Euclidean algorithm.
2. This stuff is soooo cool to learn about!! I actually enjoyed reading! :) I was wanting to know what a birthday attack was (cause it sounded fun, even though I'm sure it's not as exciting as it sounds). I thought that the one-time pad was really cool to learn about, and would love to learn more. I just didn't know what crazy stuff they had in cryptography, but I've always been fascinated and interested. I also thought it was really interesting to read about all the ways that we're kept safe online with our credit card numbers, digital signatures, and the section about games was pretty sweet too! I can't wait to learn about these things.
