It is the sneaking that open all the doors. The NSA needs to secretly intercept our messages at any point. Thus they need open doors in the network an that open the entire infrastructure o spies.
If the NSA and the counter parties just agreed to spying before hand, then these open doors would close. NA causes these problems, the cyber security pros are dumbfounded.
The massive monthslong hack of agencies across the U.S. government succeeded, in part, because no one was looking in the right place.
This was a failure to understand stable network protocols. What the NSA wants is the equivalent of door keys for every node on the network. Passing those door keys around will always be more unstable, as there are as many keys as network nodes. They do not meet congestion rules, they need a prior agreement that is stable that opens a particular door. This better model treats the carrier network as 'do not care', there is a prior protocol to manage doors and prevent congestion.
NSA needs to understand this, then they need a rethink on how many doors make efficient use of spying. They have a marginal call, and their mathematicians shoudll get on their case about this, it is almost a proven problem.
