Several years of Tempest (EMR-shielded) documentation (1985-2014): https://cryptome.org/nsa-tempest.htm Tempest timeline (1700s-2001) https://cryptome.org/tempest-time.htm Full compromising radiation protection is extremely hard to accomplish, maybe impossible, and the topmost is highly classified. Just about anything transmits radiation to a greater or lesser extent, bodies, clothing, air, feces, sweat, et al. Most protection systems transmit while seeming to block, in that way leaky like crypto. Crypto emanates. Your best friends and lovers and cohorts emanate, like GitHub. Perhaps join NSA, best of all one of its wizard contractors, or, if you get pretty good, USG or another spy agency they will grab you with an irresistable offer. Just don't succumb to Julian Assange's or Cody Wilson's tempestation. Semen may emanate above all others, shield it. At 10:00 AM 10/15/2018, you wrote:

Consider utilizing a github / wiki somewhere for this project, People can join together to generate the motivations and goals, outline areas of research, hacking and acquisitions needed, develop workplans, reproducible test setups, progress, results, costs, etc. Perhaps also some form of makerspace later on.

Okay. I made these:

- gitlab wiki: https://gitlab.com/xloem/openemissions/wikis/FAQ-and-Discussion - chat: #openemissions:matrix.org on matrix and #openemissions on freenode - loomio decision-making group: https://www.loomio.org/g/MYQFl2dC/open-emissions

I struggle with organization and would really appreciate any work to make things more organized.

If anybody is interested in collaborating actively on this right now, chat is most convenient for me at the moment.

Any power going into such a room should use a UPS battery to prevent data leakage through power lines/usage. (Would power lines become an antennae for electro-magnetic frequency leakage?) Would a UPS be sufficient enough for security?

Your use of 'UPS' seems a little ambiguous here. I have been thinking of keeping a 12V battery inside the room, and using only DC power. AC power seems like just another source of emissions to track, to me.

My understanding is that filters are placed on lines to prevent any but acceptable frequencies being carried on them. The field of electromagnetic compatibility covers this a lot, I think. Power lines completely behave as antennae, and couple nearby signals from one end, to the other, by receiving them and then re-radiating them.

Filtered AC power could be plugged straight into the mains, but I don't at this time have the experience to trust the filters, and it complicates construction of the room to make an additional penetration for the wiring.

...

And if network connectivity is needed, to prevent network cables from being a carrier of EMF leakage, perhaps fiber optic line?

As above, I think sneakernet is the way to go for highest security.

With regard to fiberoptic transmissions, it seems to me the gold standard would be open-source transcievers that are shielded to decrease the utility of compromising them, and a way to sniff the fiber-optic line to verify it does not carry unexpected data.
