For myself, I do not believe that the IETF has any interest in the Brainpool curves. The different ways would be: 1. Submit a document in the COSE WG - no something I would be interested in 2. Submit a document to the ISE - a reasonable way forward in my opinion 3. Just put the IANA registrations in to the ISO/ICE document and send a request to IANA for registration - my preferred way forward. Jim From: COSE <cose-bounces@ietf.org> On Behalf Of Mike Jones Sent: Tuesday, March 3, 2020 2:54 PM To: cose@ietf.org Cc: Anthony Nadalin <tonynad@microsoft.com> Subject: [COSE] Registering Brainpool curves for COSE The working group ISO/IEC JTC 001/SC 17 "Cards and security devices for personal identification" Mobile Driver's License (mDL) specification uses the Brainpool curves defined in RFC 5639, M. Lochter et. al., Elliptic Curve Cryptography (ECC) Brainpool Standard Curves and Curve Generation, March 2010 with COSE.. Thus, it would like to have curve identifiers registered for them. Specifically, these curves and intended registration information are: brainpoolP256r1 RFC 5639 -65537 ECDH/ECDSA brainpoolP320r1 RFC 5639 -65538 ECDH/ECDSA brainpoolP384r1 RFC 5639 -65539 ECDH/ECDSA brainpoolP512r1 RFC 5639 -65540 ECDH/ECDSA Is the best way to register these curves to create an Internet Draft and submit it to the COSE working group or would you suggest another course to accomplish this? Thanks, -- Mike
