    abstract =  {This document describes an extension to the TCP Authentication Option (TCP-AO) to support its use over connections that pass through Network Address Translators and/or Network Address and Port Translators (NATs/NAPTs). This extension changes the data used to compute traffic keys, but it does not alter TCP-AO's packet processing or key generation algorithms.},
