(Interesting) I found myself thinking specifically about the one time pad after completing the reading tonight. It appears to be a wonderful design in theory, but it seems in reality nearly impossible. However, I think that even in theory it falls short when we consider Kerchoff's principle: The security of the system depends on the key and not the obscurity of the cryptosystem. The key in a one-time pad is quite impractical, since the key is the same length as any message, and the key can only be used once to ensure security. The key must first be passed over a secured line of communication, or must be encrypted itself, which seems to create some redundancy for a cryptosystem. In a world where the transfer of important information is often time sensitive, the one-time pad has too many shortcomings to be implemented yet.
(Difficult) I had trouble understanding the Blum-Blum-Shub random bit generator.
