    abstract =  {This document describes BGPsec, an extension to the Border Gateway Protocol (BGP) that provides security for the path of autonomous systems through which a BGP update message passes. BGPsec is implemented via an optional non-transitive BGP path attribute that carries a digital signature produced by each autonomous system that propagates the update message.},
