A Profile for Autonomous System Provider Authorization
draft-ietf-sidrops-aspa-profile-01
Abstract
This document defines a standard profile for Autonomous System
Provider Authorization in the Resource Public Key Infrastructure. An
Autonomous System Provider Authorization is a digitally signed object
that provides a means of verifying that a Customer Autonomous System
holder has authorized members of Provider set to be its upstream
providers and for the Providers to send prefixes received from the
Customer Autonomous System in all directions including providers and
peers.

The primary purpose of the Resource Public Key Infrastructure (RPKI)
is to improve routing security. (See [RFC6480] for more

to verify that a AS has permission from a Customer AS (CAS) holder to
send routes in all directions. The digitally signed Autonomous
