What is a basepoint? the term is used on page 365, line two. So the analogy of a in ElGamal is a, the random number k is k. The method seems pretty straightforward. But, is it like ElGamal in that Alice cannot pick the same random integer several times over? What would the dangers of this be?
Is there an RSA implimentation using elliptic curves?
I am looking forward to tomorrow's lecture and learning about identity based encryption. It was somewhat revelatory when I read that even though a message can be signed by a system, the person might deny that it is their system, that someone else made a system and ascribed it to them.

16.4 Monday December 5th.
Today we read about elliptic curves over finite fields. This seemed really complicated. I don't understand a model for why the derivatives disapear in a finite field mod 2. I mean, yes the derivative of y^2 is 0*y*y' mod 2 but what does this look like? further, is there a way to visualize what a polynomial in a finite field looks like? the same way that we can graph a polynomial in the reals? I am not sure that I understand this and it has been a while since 371.
When are we going to start the final? Will it be like the group project where we get to break all kinds of cool systems, or will it be more along the lines of the other tests, but we get to take it home?
