Subject: [Suit] Value of
COSE_Mac_Tagged/COSE_Sign_Tagged/COSE_Mac0_Tagged/COSE_Sign1_Tagged

Hi all,

I am not sure this is the right place to ask.

This is the feedback from the TEEP-wg after the virtual hackathon and
interim meeting.

TEEP was using
COSE_Mac_Tagged/COSE_Sign_Tagged/COSE_Mac0_Tagged/COSE_Sign1_Tagged.
Are these tags defined the value in some drafts or iana?
When we were trying to implement the teep, we could not put the bstr or
int/uint for the tags.

I the draft-ietf-suit-manifest-01, it also using these tags in page 43,
https://tools.ietf.org/html/draft-ietf-suit-manifest-01

as

SUIT_Authentication_Wrapper = [ + (
     COSE_Mac_Tagged /
     COSE_Sign_Tagged /
     COSE_Mac0_Tagged /
     COSE_Sign1_Tagged)
]

COSE_Mac_Tagged = any
COSE_Sign_Tagged = any
COSE_Mac0_Tagged = any
COSE_Sign1_Tagged = any

It was deleted in teep at the link bellow of the pull request after the
discussion from the hackathon,
https://github.com/ietf-teep/teep-protocol/commit/151e72b0ea3ab8ff8f59ea4200
4180d90006f8c9
but would be nice to know if it was OK with similar bellow,

COSE_Mac_Tagged = 1
COSE_Sign_Tagged = 2
COSE_Mac0_Tagged = 3
COSE_Sign1_Tagged = 4

Thanks,
-Akira
