Wednesday Dec 1 Section 16.2

   Today was on elliptic curves and encrypting messages.  The problem is similar to the discrete logarithm problem.  With the added complication that there is a chance that your message will be unable to be encrypted.  The message is encypted by taking the message, turning it into a number and that number becomes the x coordinate of the point that represents the plaintext.  But I can't find out how the message is encoded.  Elliptic curves can be used to factor polynomials.
  So the method of encryption has to do with the fact that if B=kA, for a given B and A, k is hard to find.
