Title : BGP Prefix Origin Validation
Author(s) : P. Mohapatra, et al.
Filename : draft-ietf-sidr-pfx-validate-00.txt
Pages : 11

A BGP route associates an address prefix with a set of autonomous
systems (AS) that identify the interdomain path the prefix has
traversed in the form of BGP announcements. This set is represented
as the AS_PATH attribute in BGP and starts with the AS that
originated the prefix. 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.
