	Title		: Secure BGP (S-BGP)
	Author(s)	: C. Lynn et al.
	Filename	: draft-clynn-s-bgp-protocol-01.txt
	Pages		: 77

The Border Gateway Protocol (BGP), which is used to distribute
routing information between autonomous systems (ASes), is a critical
component of the Internet's routing infrastructure.  It is highly
vulnerable to a variety of malicious attacks both in theory and in
practice, due to the lack of a scalable means of verifying the
authenticity and legitimacy of BGP control traffic.  This document is
a protocol specification for Secure BGP (S-BGP), an extension to
BGP-4.  S-BGP adheres to the principle of least privilege and uses
countermeasures that create an authentication and authorization
system that addresses most of the security problems associated with
BGP.  To facilitate adoption and deployment, S-BGP is designed to
minimize the overhead (processing, bandwidth, storage) added by its
countermeasures and to be interoperable with the current BGP so as to
be incrementally deployable.

NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
