          An Infrastructure to Support Secure Internet Routing

Abstract

   This document describes an architecture for an infrastructure to
   support improved security of Internet routing.  The foundation of
   this architecture is a Resource Public Key Infrastructure (RPKI) that
   represents the allocation hierarchy of IP address space and
   Autonomous System (AS) numbers; and a distributed repository system
   for storing and disseminating the data objects that comprise the
   RPKI, as well as other signed objects necessary for improved routing
   security.  As an initial application of this architecture, the
   document describes how a legitimate holder of IP address space can
   explicitly and verifiably authorize one or more ASes to originate
   routes to that address space.  Such verifiable authorizations could
   be used, for example, to more securely construct BGP route filters.
