E2E security in 5G can be addressed through network slicing, another 
concept which seems to be included in many 5G proposals. If each 
application has its own slice, it can screw up but wont be able to 
affect other applications. Within each slice, E2E security can be 
enforced in an application specific manner. Even better would be if we 
can make each flow be its own slice. This may seem to be overly 
heavyweight, but is along the lines of what Bromium  is trying to do for 
desktops, isolating processes and data from each other using 
"microvisors": http://www.bromium.com/why-bromium/how-we-do-it.html We 
just need to do it for networks :)
