What is the "Cybersecurity Fabric"? I see it mentioned a lot, but having trouble filling in details.

Update: I found the answer and the research paper[1]. Based on what I've gleaned so far, this looks pretty awesome. It's like.. Horcruxes, but the participants assemble it blindly and instead of getting a soul, you get access to something without revealing the key.
