The first little bit of this section went over what we talked about in class yesterday, going over applying different cryptosystems to elliptic curves and how you might translate some of the same ideas into elliptic curve math.
The diffie hellman key exchange follows suit, in that we are translating an idea we have covered before and putting it into elliptic curves and this part seems pretty straightforward.
The signature part again seems like a concept that I should be able to understand better but i was a little confused when it starting talking about how k and k^-1 dont multiply to get one but sometimes you could get out infinity. If k is just an integer shouldnt it just come out as one? k can't be a point because that would make k^-1 make even less sense...
