1. I don't remember how to make sure the message is a point on the curve, and this section didn't explain it (that I could understand).
2. It was good to read this after already talking about it in class a couple times. It made sense. :)

16.4, due on December 7
1. I don't really understand what is going on when we add three points only to then add two points to find something that adds to infinity. I'm also having a hard time grasping the concept of working over a finite field GF(2^n).
2. This is random and unimportant, but I liked learning that a singularity is a point "where the partial derivatives with respect to x and y simultaneously vanish." I don't know if I've ever heard of that, but I think it sounds cool and interesting.

1. I didn't really understand the algorithm for factoring using elliptic curves. You just choose random curves until one of them works for you? How long do you wait before you deem one ineffective?
2. This section kind of felt like a lot of random things about the elliptic curve factoring algorithm without actually doing a good job of explaining how the algorithm itself works. But it could have been there and just went all over my head.
