( Well I'm sure that there is a few hundrends of paper on this subject ) I have a few ideas but it involve: .Dark Fiber; . All devices at FIPS 140 level; . Tonnes of resin; . Wire mesh; . Fiber DB monitoring; . Cable Shield monitoring; . Single Encryption Key injection for the FIPS 140 devices; . Central Provisioning; . Kill switch for suspected segments; <add your own crazy ideas> <etc> <add more of your own crazy ideas> And a private fab because it would not be a good idea to sub-contract that to lets says... some Chinese outfit =D TLDR: Feasable, hella costly.
