IETF logoIn April, I wrote about several useful developments in the IETF Secure Patterns for Internet CrEdentials (SPICE) working group. I’ve recently contributed to progressing several specifications in preparation for the SPICE working group meeting at IETF 123 in Madrid. Here’s a tour…

I’ve become a contributor to the Selective Disclosure CWT (SD-CWT) specification. The draft we just published in preparation for IETF 123 contains significant enhancements, including better alignment with both SD-JWT and CWT, clearer and simpler specification of the use of encryption, creation of the Verifiable Credential Type Identifiers registry, using a CBOR simple value for redacted claims, and numerous editorial improvements. See the history entry for more details. This was joint work with Rohan Mahy and Orie Steele.

I’ve become an editor of the OpenID Connect Standard Claims Registration for CBOR Web Tokens specification, along with Beltram Maldant. It creates CWT equivalents of the standard JWT claims defined by OpenID Connect. The draft we just published in preparation for IETF 123 aligns the terminology used with OpenID Connect. I believe it’s ready for working group last call.

Brent Zundel and I updated the GLobal Unique Enterprise (GLUE) Identifiers specification to fix some links and update his association to Tradeverifyd. I believe this one is also ready for working group last call.

Finally, Brent and I updated the Traceability Claims specification to tighten up many of the claim definitions. See the history entries for details.

I’m looking forward to continued progress at the SPICE meeting in two weeks!
