Document writeup for draft-ietf-sframe-enc-06

# Document History

This document is the input document that caused the formation of the SFrame
working group.  It is substantially the same as that original input on a
technical level, though many aspects of that design have been tested in the
working group. The editorial quality is significantly improved and more robust
security and deployment considerations are now present.  The one major addition
was the inclusion of a concrete usage of MLS for key management, which was
originally in a separate draft.

This work spent a long time without a lot activity, interspersed with short
bursts of high productivity.  The WG chairs believe that sufficient input has
been received despite this.

Implementations and deployments exist.  Test vectors are included and are
produced and checked by an automated system.

# Reviews

This document includes a very straightforward integration of AEAD and HKDF.
Careful security review from outside of the working group will be helpful, but
this shepherd believes that this has a low risk profile due to the extreme lack
of novelty.  There is no formal analysis.

# Checks

The document is clear and precise.  The design is sensible and appropriately
scoped.

Checked: Status (std), IPR (checks in progress), issues, idnits (what a trash
fire of a program), references (no downrefs, no unfinished work), registries.

# Registry Experts

A new registry is established for ciphersuites.  This will need experts.  I
recommend that this include all of the draft authors (checking with authors in
progress).
