[cryptography] Radiation Emission Controls

[John Young]

More specifically inadvertent emissions like Non-Stop,
acoustic, vibratory, olfactory, echo, refractory, extent,
periodicity, amplitude, array, those still loosely or firmly
classified. Those somewhat treated of sea and space
borne vessels by degaussing, presumably more difficult
for aged architecture and infrastructure but maybe not
for new facilities like NSA Utah, other data centers and
global research networks.

If NRAO can assign sigs to several billion stars that should
be possible for several billions cellphones, buildings and
infrastructures.
