[Cryptography] The Laws (was the principles) of secure information systems design

> "Virtual" -- Looks like something that it isn't.
Virtual:  Something that appears to be there although it isn't.
Transparent:  Something that appears not to be there although it is.

When someone tries to sell you something that's "virtually transparent", you know what you're getting.
