There is a spread spectrum radio tech where you broadcast on
essentially all frequencies / wideband at once. To the eavesdropper
it appears as simply a rise in unlocatable background noise levels.
Yet there is a twist... you and your peer posess a crypto key. That
key is used to select and form a broadcast/reception frequency map
over the entire spectrum. You drive it with software radio. Think of the
map as a vertically slotted grille mask over your spectrum analyzer.
The grille spacing/width/overlap is random. What you see is your
distributed signal hidden in the noise. Pass it down your stack
for further processing and decoding.

It's been a while since I've seen this described, whether formally, or
applied. Link to paper[s] covering the topic would be appreciated.
