Could we make the route extension more efficient by using HMQV(hashed Menese-Qu-Vanstone)? MQV is patented, but I don't know about HMQV. This would 2/3 the load on servers when doing a negotiation(3 exponentations vs. 2 exponentiations). since most routes are reletivly-short lived this would reduce load by a significant amount. All results against it require leakage of the random nonces used.
