2.9-2.11 due sept 18

Difficult: 
For the one time pad, I don't understand why the key is so expensive to produce. Can't a computer generate a list of random 0s and 1s without too much effort?  Also, I didn't understand how the BBS random generator operated (though it has a great name!). 

Reflection:
It was interesting to realize that companies often had to choose between security and speed.  I didn't realize that security influenced speed and vice versa when it came to encryption, but it makes sense.
