The full TEMPEST specs are more or less classified, as might be expected. (Because one does not lightly tell one's enemies what one is measuring for.)

Contrary to popular rumor, it is not "illegal" to shield computers, to "use TEMPEST methods," as it were.

Rather hard to see how it could be, given that the details are supposed to be secret! If all of a sudden you got arrested for wrapping wet towels around screens that would be a Big Clue.... (of course that assumes you live in a country where you get told what you;ve been arrested for. Hmmmm....) Ken
