Whole Disk Encryption may not be Secure Enough

This just shows that nothing that is easily accessible to the user can be fully protected from an attacker. Every lock HAS to have a key, and no matter how strong the lock and safe are, the key still has to be protected.

If I understand it, this is similar to how the new BluRay and HD-DVD protection has been broken. Software that plays these disks has the have the KEY somewhere in it, somewhere in memory. All the can do is try and hide it. But you've given the KEY out freely, and just hope no one can find it unless using the authorized software. That's just silly.
