All,

I’ve been thinking though some of the problems with cryptography.  I have a question.  How do we protect the image?  It seems to me that the easiest way to circumvent the cryptography features of a system would be to change the code to send off plain text after it was decrypted.  So the question is how do we protect the image from being tampered with?  Is this even a valid concern, or do we assume that once someone has access to the machine, and therefore the image, that the system is compromised in general?
