TEMPEST?
A set of standards for allowed levels of emissions (in particular,
electro-magnetic radiation) from communication/computing gear, intended to
prevent listening to the activity of that gear:

Thanks, very interesting reading and this must be a quite sensitive
topic. As one party tries to develop equipment according to this
standard, other parties will try to "listen" even than...

One of the more interesting Tempest creations is a font (for CRT displays, i.e., ones with
analog video) that drastically reduces the emissions from the video signal. It was
created by Markus Kuhn and Ross Anderson at U. Cambridge.

Quite interesting, but I believe that nowadays this is a
smaller problem than the omnipresent internet connection
and the huge amount of black-box software with even more
backdoors, security-holes and calling-home features which
all are claimed to be there just to make software better and
help the customer. OK, this thread is drifting away from the
vintage computing field ;-)
Thanks for the link!
