Re: [lamps] Proposed Re-Chartering Text for CMP updates and lightweight profile (RE: Follow-up on lightweight CMP profile)

Hi Russ

Did you have the time to look into my mail below?
I would like to push this topic further forward.

Betreff: AW: Proposed Re-Chartering Text for CMP updates and lightweight profile (RE: Follow-up on lightweight CMP profile)

Hi Russ

We discussed my proposal on the mailing list. I feel there is quite some support.
Tomas, Max and Martin supported the activity. There were some questions and concerns from Panos, that I hopefully could clarify.

What is the next step?

Betreff: [lamps] Proposed Re-Chartering Text for CMP updates and lightweight profile (RE: Follow-up on lightweight CMP profile)

Hi Russ, all,

as discussed at IETF104 and on this list we would like to spend further work on updating and profiling CMP focusing on industrial use cases.
To get input, feedback and support from LAMPS we propose the following charter text.

As certificate management gets increasingly important in industrial environments, it needs to be tailored to the specific needs. CMP as existing protocol offers a vast range of options. As it is already being applied in industrial environments it needs to be enhanced to more efficiently support of industrial use cases, crypto agility and specific communication relations on the one hand and profiled to the necessary functionality on the other hand to ease application and to better facilitate interoperable implementation.

Hendrik:

The current re-charter is about two weeks away.  You would need to propose text for the charter on this list, and see if there are people that will review and implement.

Hi all

Referring to the Email thread 'Seeking guidance on proceeding with question from IETF-104 presentation on lightweight CMP profile' and to the outcome of the WG meeting, we want to summarize the current state of the discussion.
The discussion we had with Jim motivate a split of the current draft into a CMP Updates and a CMP Profile document. The update of CMP is needed because we identified at least two point where a change to CMP is needed:
- Change the type of encryptedCert from EncryptedValue to EncryptedKey for ECC and post-quantum algorithm support
- Extend the RootCAUpdate announcement message to e request/response message to enable requesting the update from the client side
The remaining points from the initial email were seen as profiling topic and would therefore be handled in the CMP Profile document..

@Russ, how do you see the status of the current re-chartering process? Would you support to add both, or at least the CMP Updates, activities under the revised charter?

- Hendrik
