Now that it appears the Internet is compromised what other means can rapidly deliver tiny fragments of an encrypted message, each unique for transmission, then reassembled upon receipt, kind of like packets but much smaller and less predictable, dare say random?
The legacy transceiver technologies prior to the Internet or developed parallel to it, burst via radio, microwave, EM emanations, laser, ELF, moon or planetary bounce, spread spectrum, ELF, hydro, olfactory, quanta, and the like.
Presumably if these are possible they will remain classified, kept in research labs for advanced study, or shelved for future use.
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.
