TLS/1.2 transport

The most recent draft of the "Updates to the TLS Transport Model for SNMP"
is now available at
https://www.ietf.org/archive/id/draft-ietf-opsawg-tlstm-update-02.html.

This document is being developed by OPSAWG, but obviously relates to TLS so
we would like to make sure that there is full awareness of this document
within both groups before we start the process to finalize the document.
This version reflects the discussions during IETF 113 and creates a TLSTM
HashAlgorithm registry that will initially parallel the entries in the TLS
(1.2) Hashing Algorithm Table. However, whereas TLS experts have expressed
a desire to freeze the TLS Hashing Algorithm Table (to prevent new hashing
algorithms from being used with TLS 1.2), the TLSTM HashAlgorithm registry
will continue to add values as needed (so that the TLSTM fingerprint
algorithm can still be used with minimal impact to existing code). We have
also added the following two requirements to section 6 (IANA
Considerations):
- A new entry MUST be added to the TLSTM HashAlgorithm registry when new
(D)TLS hashing algorithm are defined.
- Any updates to the existing IANA TLS Hashing Algorithm Table MUST be
consistent with the assignments in TLSTM HashAlgorithm registry (it is not
expected that the TLS Hashing Algorithm Table will ever be updated, but the
backwards compatibility of the standard is premised on this assumption so
the constraint must be stated)

Other changes include:
Revised the title and abbreviation to be an update with no reference to TLS
version number.
Removed references to 1.3 except where needed
Deleted paragraph regarding the terminology of "principle" as the term is
not used.
Removed double quotes around "obsolete" within SnmpTLSFingerprint
DESCRIPTION clause.
Revised text to use a consistent name for the proposed hash algorithm table
(TLSTM HashAlgorithm Registry)
Removed references not used in this document
Removed appendix examples (i.e., the examples in RFC 6353 no longer need to
change)

The one change that was suggested and not implemented was a request to add
additional hashing algorithms to the proposed table. I believe the proposal
was to add the additional algorithms that are included in an INCOSE table
(with newly assigned numbers). I searched for such a list but could not
find one. Perhaps I misunderstood the source for this list? I am happy
extend the list if someone can provide the correct reference.

I believe this version is near final and I am notifying by both the OPSAWG
and TLSWG to review to ensure that we have consensus. I welcome your inputs.

Ken Vaughn

Abstract:
  This document updates the TLS Transport Model (TLSTM), as defined in
  RFC 6353, to reflect changes necessary to support Transport Layer
  Security Version 1.3 (TLS) and Datagram Transport Layer Security
  Version 1.3 (DTLS), which are jointly known as "(D)TLS".  This
  document is compatible with (D)TLS version 1.2 and is intended to be
  compatible with future versions of SNMP and (D)TLS.

  This document updates the SNMP-TLS-TM-MIB as defined in RFC 6353.
