That doesn’t mean that Randy dare not open those files—just that he daren’t display them on the screen. This distinction is crucial. Ordo can read the encrypted files from the hard drive. It can write them into the computer’s memory. It can decrypt them, and write the results into another region of the computer’s memory, and leave that data there indefinitely, and the Van Eck phreakers will never be the wiser. But as soon as Randy tells the computer to show him that information in a window on the screen, the Arethusa intercepts will belong to the Van Eck phreakers; and whoever they are, they can probably break them faster than Randy can.
