Difficult:
I don't fully understand how the short plaintext attack works. It appears that we are somehow getting a subset of keys of to try instead of having to try all possibilities. I'm mainly not sure how we got that subset of things to try. I also think that timing attack are impressive but would have no idea about how to implement one.
Reflective:
It seems that encryption methods are always safer when we refuse to cut corners. It looks like most encryption methods are made unsafe when people try to make it quicker or easier and thus they lose some key element that made the encryption method safe. I think it's interesting that at the beginning of the chapter it said RSA is safe as long as it is implemented correctly and then went on to describe all the bad things that happen when it isn't implemented correctly.
