1. The difficult part was understanding the elliptic curve Diffie-Hellman Key Exchange. It gave an example and threw out some numbers, so it took some time to understand what was going on.
2. I though that the similarity between the ElGamal Digital Signitures and the Elliptic Curve version was very interesting, since they basically look the same.

16.4 for 7 December
1. The most difficult part was understanding the example using an elliptic curve over GF(4). I was not completely sure why some of the polynomials that resulted from plugging in elements of GF(4) had no solutions.
2. Using elliptic curves over GF(2^n) seems like it should be useful for computer applications since computer scientists always seem to like things to be in powers of 2.
