The document, along with other ballot positions, can be found here: https://datatracker.ietf.org/doc/draft-ietf-cose-hash-sig/ ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- Thanks for the work that went into creating this document. I have no comments on its contents (the crypto is somewhat outside my area of expertise), although I have a few observations regarding the examples. --------------------------------------------------------------------------- Appendix A: > This appendix provides a non-normative example of a COSE full message > signature and an example of a COSE_Sign1 message. This section > follows the formatting used in [RFC8152]. I would suggest that RFC 8610 might be a better reference here, as it is the document that actually defines the extended CBOR diagnostic format. In particular my recommendation is: "This section is formatted according to the extended CBOR diagnostic format defined by [RFC8610]." --------------------------------------------------------------------------- §A.1: > 98( > [ > / protected / h'a10300' / { > \ content type \ 3:0 > } / , > / unprotected / {}, > / payload / 'This is the content.', > / signatures / [ > [ > / protected / h'a101382d' / { > \ alg \ 1:-46 \ HSS-LMS \ > } / , > / unprotected / { > / kid / 4:'ItsBig' > }, > / signature / ... > ] > ] > ] > ) I think there are two things here that need to be addressed. First, section 3 of this document specifies: > o The 'kty' field MUST be present, and it MUST be 'HSS-LMS'. I can't find a 'kty' field in this example. Also, this example uses '-46' as the identifier for HSS-LMS, while section 6.1 specifies the value as "TBD." This example needs a clear note added for the RFC editor that the "-46" needs to be replaced by the IANA-assigned value. A similar annotation will be required for the 'kty' field, regarding the value assigned for section 6.2. --------------------------------------------------------------------------- §A.2: Same comments as A.1, above. _______________________________________________ COSE mailing list [email protected] https://www.ietf.org/mailman/listinfo/cose
