Difficult: The steps of the cryptosystems here are all rather difficult to follow, I look forward to seeing examples in class. I'm ha...

Difficult : The discussion of addition with these elliptic curves was much more confusing than before. In the example, it seemed to say...

Difficult: So we can just pick any elliptic curve and it will probably factor the number? How can we be sure within a good probability th...

Difficult: I do not quite understand the idea of encrypting messages with an elliptic curve mod p. So, you pick your message and then att...

Difficult: Why do they define addition of points on the curve as the reflection of the third point where the secant line hits the curve? ...

Difficult: I do not fully understand the discussion of the permutations used to break Enigma. The text mentions that letters never mapped...

Difficult: I found it difficult to understand what physicists (and for that matter chemists) believe about photons. Do they really think ...
