The government's concern with Tempest gear is all basically paranoia; there has been no known case of computer emissions actually spilling anything to the bad guys. Espionage cases are almost invariably "inside jobs". It is probably easier to bribe your janitors than to eavesdrop on your monitors. -- "Maybe we should tell the truth?" | Henry Spencer at U of Toronto Zoology "Surely we aren't that desperate yet." | henry@zoo.toronto.edu utzoo!henry
