Protocol Action: 'Simple Authentication Schemes for the ALC and NORM Protocols' to Proposed Standard (draft-ietf-rmt-simple-auth-for-alc-norm-06.txt)

The IESG has approved the following document:
- 'Simple Authentication Schemes for the ALC and NORM Protocols'
  (draft-ietf-rmt-simple-auth-for-alc-norm-06.txt) as a Proposed Standard

This document is the product of the Reliable Multicast Transport Working
Group.

The IESG contact persons are David Harrington and Wesley Eddy.

Technical Summary

This document introduces four schemes that provide a per-packet
authentication and integrity service in the context of the ALC and NORM
protocols. The first scheme is based on digital signatures. Because it relies
on asymmetric cryptography, this scheme generates a high processing load at the
sender and to a lesser extent at a receiver, as well as a significant
transmission overhead. It is therefore well suited to low data rate sessions.
The second scheme relies on the Elliptic Curve Digital Signature Algorithm
(ECDSA). If this approach also relies an asymmetric cryptography, the
processing load and the transmission overhead are significantly reduced
compared to traditional digital signature schemes. It is therefore well suited
to medium data rate sessions. The third scheme relies on a group Message
Authentication Code (MAC). Because this scheme relies on symmetric
cryptography, MAC calculation and verification are fast operations, which makes
it suited to high data rate sessions. However it only provides a group
authentication and integrity service, which means that it only protects against
attackers that are not group members. Finally, the fourth scheme merges the

Last Call: <draft-ietf-rmt-flute-revised-13.txt> (FLUTE - File Delivery over Unidirectional Transport) to Proposed Standard


The IESG has received a request from the Reliable Multicast Transport WG
(rmt) to consider the following document:
- 'FLUTE - File Delivery over Unidirectional Transport'
  <draft-ietf-rmt-flute-revised-13.txt> as a Proposed Standard

The IESG plans to make a decision in the next few weeks, and solicits
final comments on this action. Please send substantive comments to the
ietf <at> ietf.org mailing lists by 2012-02-24. Exceptionally, comments may be
sent to iesg <at> ietf.org instead. In either case, please retain the
beginning of the Subject line to allow automated sorting.

Abstract

   This document defines FLUTE, a protocol for the unidirectional
   delivery of files over the Internet, which is particularly suited to
   multicast networks.  The specification builds on Asynchronous Layered
   Coding, the base protocol designed for massively scalable multicast
   distribution.  This document obsoletes RFC3926.

This document contains downrefs:
It creates a registry that includes values for content encoding 
algorithms defined in Informational RFCs 1950, 1951, and 1952.
It discusses a potential weakness created by using WEBRC
congestion control, a mandatory to implement algorithm for ALC.
