Clarke, said it might be time to replace the "creaky, cranky" 20-year-old protocols that drive the Internet with standards better able to accommodate a flood of new wireless devices. Wireless devices, it is feared, may introduce large security holes to the network. The White House is working with the private sector to draft a national plan to secure the country's most vital computer networks from cyber attack.
How about IPv6 with IPSEC?
Wireless is the canonical case for geographic routing. Addresses as static or dynamic positions in space (either mutual time of flight or deriving refinable position from connection constraints), packet routing as the crow flies, local-knowledge routing tables that only know about a few km space around you, almost no admin traffic. Plus, routing logic thin enough to fit into deep embedded footprint, or be cast in hardware for relativistic speed cut-through. IPv6 can't handle most this, especially on the scale required. There's point in going IPv6, but at the same time one must be aware that this is just a patch, not a fix.
