It would seem very straightforward to progress draft-shen-sm2-ecdsa as an Information RFC, and then write a very short standards-track RFC that says how to use SM2 with COSE. It would look similar to RFC 8778.
Russ P.S. I encourage you to also write a short standards-track RFC about the use of SM2 with PKIX. It would look similar to RFC 8410. I encourage you to also write a short standards-track RFC about the use of SM2 with CMS. It would look similar to RFC 8708. > On Jun 28, 2023, at 9:00 AM, 张志磊 <[email protected]> wrote: > > Thanks for your reply. > There is already a > draft(https://datatracker.ietf.org/doc/html/draft-shen-sm2-ecdsa-02) explains > the algorithm. > and some crypto project like linux kernel、openssl、libgcrpt have implemented > SM2 Digital Signature Algorithm. > IANA has assigned the value 0x0708 with the name "sm2sig_sm3" to the "TLS > SignatureScheme" registry and IANA has assigned the value 41 with the name > "curveSM2" to the "TLS Supported Groups" registry according to RFC8998 > (https://www.rfc-editor.org/rfc/rfc8998.html#name-iana-considerations). > Is it enough to register SM2 Digital Signature Algorithm? > hope for your reply. > Thanks a lot. > > > 发件人: Russ Housley <[email protected] <mailto:[email protected]>> > 发送时间: 2023年6月28日 20:39:38 > 收件人: 张志磊 > 抄送: [email protected] <mailto:[email protected]> > 主题: Re: [COSE] how to add SM2 Digital Signature Algorithm > > I support the registration of the SM2 Digital Signature Algorithm.
