Subject: [COSE] ? Call for Consensus: CounterSignature Discussion ?
This message is to confirm consensus to deprecate the current CounterSignature
feature and replace it with one that best accounts for all COSE message types.
At the synchronous WG meeting on July 29, the issue with countersignatures was
heavily discussed. In summary, the currently-defined CounterSignature
mechanism is not processed with the cryptographic content for certain COSE
message types. The consensus from the meeting is to mark the current
CounterSignature process and structure deprecated in rfc8152bis and define a
new one that properly accounts for the cryptographic. Further consensus leaned
toward an aggressive approach, incorporating all bstr elements in the target
structure when computing the signature.
To complete the new CounterSignature method, the sense in the meeting is to
have a series of virtual interims. The details of the new method and where it
fits as working group items is still to be determined. Jim Schaad posted a
starting proposal for a method[1], and an initial discussion on how to approach
this as a working group item[2].
Given the participation in the meeting is very close to the participation on
the list, we are only seeking objections. If you have objections, please
inform the list and why you object. A following message will propose times for
interims, ideally starting this month (August).
Thank you,
- Ivaylo and Matthew
