1. (Difficult): I don't remember why x congruent to y2*y1^-a decrypts for the ElGamal Cryptosystem and I forgot how to encrypt a message to a point using Elliptic Curves. The former I can review myself I think but a review of the latter in class would be helpful.
Also, I didn't understand the end of the ElGamal Digital Signatures when it says n=p-1 and when it talks about arbitrary assigned integers to points.
2. (Reflection): The Elliptic Curve Diffie-Hellman Key Exchange I got! And elliptic addition/multiplication being analogous to regular multiplication/exponentiation makes some sense. That's good.
This is our last blog. Wow time flies!
