Re: [lamps] WGLC for draft-ietf-lamps-cms-sha3-hash

These will be useful for KEMRI with ML-KEM since it uses lots of variants of
SHA3 and SHAKE under the covers so we will want a KDF using at least one of
those.

 

While going over the draft I just found a few nits:

 

Section 3.1:

Trailing braces on the following line:kmac

                The RSASSA PKCS#1 v1.5 is defined in [RFC8017]}}.

 

Section 5.1:

"algorithm" is misspelled:

                [I-D.ietf-lamps-cms-kemri] is one place where algrithim
identifiers

 

Section 6:

Remove either "cryptographics" or "such" from the following line:

number generators (PRNGs) to generate cryptographic such values can

 

The id-alg-hkdf-with-sha3-* object identifiers are currently TBD.  Since
cms-kemri and cms-kyber implementation and interop is going on right now in
the hackathon group, it would be nice to have those assigned.  Is it too
late for early assignment?  Is it too early for normal assignment?  I don't
know if those OIDs will be the ones recommended by cms-kyber, but it would
be nice to have some OIDs for specs that aren't paywalled (kdf2, kdf3).

 

Thanks,

Daniel

Subject: [EXTERNAL] [lamps] WGLC for draft-ietf-lamps-cms-sha3-hash

 

Hello,

 

Russ has suggested that draft-ietf-lamps-cms-sha3-hash might be ready for
WGLC, and since it's a pretty simple draft that seems like a pretty
reasonable way to flush out any remaining comments and problems.

 

Therefore this is the WGLC for draft-ietf-lamps-cms-sha3-hash:

 

Use of the SHA3 One-way Hash Functions in the Cryptographic Message Syntax
(CMS)

https://datatracker.ietf.org/doc/draft-ietf-lamps-cms-sha3-hash/

 

Abstract

 

   This document describes the conventions for using the four one-way

   hash functions in the SHA3 family with the Cryptographic Message

   Syntax (CMS).

 

Please send comments to the list by 12 February 2024.
