Technical Summary

To help reduce well-known threats against BGP including prefix mis-
announcing and monkey-in-the-middle attacks, one of the security
requirements is the ability to validate the origination AS of BGP
routes. More specifically, one needs to validate that the AS number
claiming to originate an address prefix (as derived from the AS_PATH
attribute of the BGP route) is in fact authorized by the prefix
holder to do so. This document describes a simple validation
mechanism to partially satisfy this requirement.
