Dear Ronald,

Thanks for your request to make SM4 an Internet Draft under the IRTF
stream. We assume you are asking for this document to be adopted by CFRG.

The CFRG co-chairs are considering your request carefully and will get
back to you soon with a response.

Best wishes,

Alexey and Kenny

Dear Members of the CFRG,

We started an Internet Draft to detail the workings of the SM4 block
cipher and would like to submit this Internet Draft under the IRTF stream.


SM4, currently the only China-approved symmetric encryption algorithm,
was recently standardized as a Chinese standard (GB/T 32907-2016) and is
also on track in being published as ISO/IEC 18033-3/AMD2 this year.


All its previous iterations / standards were only available in Chinese,
including those from 2003 (GB 15629.11-2003), 2006 (OSCCA), 2012 (GM/T
0006-2012) and 2016 (GB/T 32907-2016). The upcoming ISO/IEC 18033-3/AMD2
however will be in English,
but slightly abstracted. There was an unofficial English translation
dating to 2008 on IACR, but the algorithm was slightly modified since the
2012 version. Another purpose of this document is to serve as a stable
reference for future IETF documents.


With SM4’s rather long history and there are plenty of implementations
out there, including Botan (we contributed SM4), GmSSL (Chinese fork of
OpenSSL), Intel’s IPP, and a number of hardware implementations including
TCG’s Trusted Platform Module (TPM).

The draft is available here:
https://tools.ietf.org/html/draft-ribose-cfrg-sm4-00


From my understanding of RFC 5743 we need a RG to review this work, and
we tried to make the draft follow RFC 5743 rules as closely as we can.


Would the CFRG be interested in reviewing this document and perhaps
assigning a RG / Editor?

Thank you very much — your feedback is much appreciated!

Kind regards,
Ronald

P.S. There are two minor typos in the draft but somehow draft replacement
isn’t working at the moment in the datatracker.
