Comment So eavesdrop at the endpoints? (Score 1) 102
Without having really understood the physics behind this, what I gather is that it basically would allow you to conceal optical signals from eavesdropping on the transmission line. But that's only on the transmission line. Obviously the transmitted data still needs to exist at the endpoints in one form or another... so eavesdrop on the endpoints instead? Unless you have a true point-to-point line, your data will also likely be routed over some sort of IP network, where it will have to exist in some other form for at least short periods of time.
