Subject: [Jose-reg-review] Request to register JOSE algorithms for the FIDO




The FIDO Alliance would like to register the following algorithms in the
IANA "JSON Web Signature and Encryption Algorithms" registry:

1. "ED256", see

2. "ED512", see

3. "ED638", see

4. "ED256-2", 

    - Name "ED256-2"

    - Algorithm Description: ECDAA algorithm based on ECC_BN_DSD_P256 (
.0-id-20180227.html#bib-DevScoDah2007) curve using SHA256 algorithm.

    - Algorithm Usage Locations: "alg", i.e. used with JWS.

    - JOSE Implementation Requirements: optional

    - Change Controller: FIDO Alliance,  <> 

    - Sections 3. FIDO ECDAA Attestation (
.0-id-20180227.html#fido-ecdaa-attestation) and 4. FIDO ECDAA Object Formats
and Algorithm Details (
.0-id-20180227.html#fido-ecdaa-object-formats-and-algorithm-details) of

    - Algorithm Analysis Document(s):

("ED256-2" should have also been in the IANA Considerations section but
isn't due to a clerical error.)


These names are related to cryptographic algorithms for Direct Anonymous
Attestation.  The relevant details are described in

The algorithms were developed by Jan Camenisch of IBM (cc'ed) - a
cryptographic expert.  They are in production use in FIDO deployments.
