Title : Security Requirements For TRACK
Author(s) : T. Hardjono, B. Whetten
Filename : draft-ietf-rmt-pi-track-security-00.txt
Date : 21-Jul-00
This document discusses the security issues within the TRee-based
ACKnowledgement (TRACK) reliable multicast protocol instantiation, and
identifies some constraints and requirements for security provisions for
this protocol. Based on the constraints and requirements, the document
proposes a separation of data packet confidentiality and authentication,
from transport layer protection. It proposes that TRACK be primarily
concerned with group authentication of control and data packets, to
protect against attacks on the transport infrastructure. It proposes
that data confidentiality and source authentication be provided
separately from this low level group authentication, ideally at the
application level. We show that this is particularly important for
TRACK, because of the requirement that the interior control nodes only
OPTIONALLY have access to the data packet payload.

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.
