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. _______________________________________________ cryptography mailing list cryptography@randombit.net http://lists.randombit.net/mailman/listinfo/cryptography
