Re: Streamlining Data Integrity Cryptosuites

Speaking of CBOR-LD – what’s the plan to do something with that?

Hi VCWG (bcc: CCG),

Now that the VCWG work is under way and the CCG Data Integrity
specification has been selected as the input document for the Data
Integrity work, it's time to start nailing down some implementation
directions for the next 2+ years.

One of the first of those considerations is streamlining the way we
build Data Integrity cryptosuites. Please find a proposal attached to
this email that:

* Ideally, eliminates the need to create new JSON-LD Contexts for
cryptosuites for 80%+ of the use cases we currently have.

* Continues to ensure the ability to get large compression gains via
the use of semantic compression (e.g., CBOR-LD)

VCWG Chairs, this is a request for some time on a future call to
discuss this proposal and get VCWG buy-in on the concept given that it
will significantly impact the cryptosuites that we standardize in the
group.
