RED/BLACK Separation
TEMPEST standards require "RED/BLACK separation", i.e. maintaining distance or installing shielding between circuits and equipment used to handle plaintext classified or sensitive information (RED) and normal unsecured circuits and equipment (BLACK), the latter including those carrying encrypted signals. Manufacture of TEMPEST-approved equipment must be done under careful quality control to ensure that additional units are built exactly the same as the units that were tested. Changing even a single wire can invalidate the tests.

Famous quotes containing the words red, black and/or separation:
“To-night the winds begin to rise
And roar from yonder dropping day:
The last red leaf is whirl’d away,
The rooks are blown about the skies;
The forest crack’d, the waters curl’d,
The cattle huddled on the lea;”
—Alfred Tennyson (1809–1892)
“Richard. Give me a calendar.
Who saw the sun today?
Ratcliffe. Not I, my lord.
Richard. Then he disdains to shine, for by the book
He should have braved the east an hour ago.
A black day will it be to somebody.”
—William Shakespeare (1564–1616)
“A separation situation is different for adults than it is for children. When we were very young children, a physical separation was interpreted as a violation of our inalienable rights....As we grew older, the withdrawal of love, whether that meant being misunderstood, mislabeled or slighted, became the separation situation we responded to.”
—Roger Gould (20th century)
