But you make the assumption that "as long as most systems are secure most of the time."
which I do not find necessary.
BTW, one of the earliest references to the security design I mentioned can be
found in the Hindu governments of the Mogul period, who are known to have used at
least three parallel reporting channels to survey their provinces with some degree
of reliability, notwithstanding the additional efforts.
