Difficult: Nothing, it all made sense. The elliptic curve math is simple, and I am already very familiar with DH and ElGamal.

Reflective: I was sad to see no discussion of message encryption with elliptic curves. It is also sad to just see extensions to known methods that have man-in-the-middle attacks.

Exam Prep:
Important: Math in Z_p, Proofs about the infinitude of primes, how to factor primes, multiplicative functions, characters, encryption, and elliptic curve point addition.

Questions: Pretty much what we have seen so far, but with a focus on encryption.

Understand: There is nothing I actually feel that week on. The biggest problems I have had on the tests to date has been a lack of exactitude, which is my fault and not a problem with what I have learned.
