Re: [cryptography] Radiation Emission Controls

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.
