Title : Security Issues in PIM-SM Link-local Messages
Author(s) : J. Atwood, S. Islam
Filename : draft-atwood-pim-sm-linklocal-01.txt
Pages : 11
Date : 2006-6-27
This document proposes some additions to the specification of the
Protocol Independent Multicast - Sparse Mode (PIM-SM) Protocol
regarding security issues of its link-local messages. Although the
new specifications for IPsec architecture (RFC 4301) and
Authorization Header (RFC 4302) permit the use of anti-replay, they
counsel against its use for multi-sender, multicast Security
Associations. This makes PIM-SM vulnerable to Denial of Service
(DoS) attack. In this document, a new proposal is presented to
protect PIM link-local messages while activating the anti-replay
mechanism as well. This proposal builds on the new Security
Association lookup method that has been specified in RFC 4301 and RFC
4302.

In the body type:
"FILE /internet-drafts/draft-atwood-pim-sm-linklocal-01.txt".
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.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
