I think this is exactly what was needed/asked-for. Thank you!

Currently, we uploaded some of the referenced documents here:

@Rene, Parts 1 and 3 can be found in the link above.

 

Hope it helps.

 

Thanks,

主 题:Re: [TLS] (offline) Re: Draft for SM cipher suites used in TLS1.3

 

Hi WG chairs,

 

Can we place the referenced documents in the TLS WG GitHub?

https://github.com/tlswg

 

According to the discussion below, this can help people to read and understand the referenced specifications.

 

Thanks,

 

Kind Regards

Kepeng

IMHO, placing the documents on GitHub would be perfect, and quite sufficient. 

 

Please make sure to post the name of the repo here. ;/)

 

I leave it to others to decide whether they'd want copies of today PDF files sent to the mailing list directly.

Regards,

Uri

Good points.

 

The good news is that we have found some English PDFs of SM2, including the missing part 1 and part 3. Will continue to find English translations of other SM standards mentioned in the draft.

 

So, if we host a free website, say on Github or so, to provide those docs, is it convenient for you guys? Or should we just drop the   PDF files to this mailing list as attachments?

Arguably, "national" crypto specifications garnish more stature if these are made available to the pubic by that standard-setting body itself (who, thereby, acts as its authoritative source), without deference to a third party (that may, independently from the originator, enforce document control [e.g., by effectuating technical changes or enforcing controlled dissemination]).

 

Since your draft introducing SM cipher suites with TLS1.3 appeals to the authority of a standard-setting authority, easy availability of the full and accredited technical documentation to the IETF community helps in scrutiny and, e.g., evaluating claims in the security considerations section.

About the references to ISO documens, I think it is a general issue for IETF drafts.

 

How does the other IETF drafts make the references to ISO documents? ISO documents are often referenced by IETF drafts.

 

Thanks,

Hi Paul:
 
I tried and look up the documents GMT.0009-2012 and GBT.32918.5-2016 on 
the (non-secured) websites you referenced, but only found Chinese 
versions (and Chinese website navigation panels [pardon my poor language 
skills here]). Since the ISO documents are not available to the general 
public without payment, it would be helpful to have a freely available 
document (in English) from an authoritative source. Having such a 
reference available would be helpful to the IETF community (and 
researchers). Please note that BSI provides its specifications in German 
and English, so as to foster use/study by the community. If the Chinese 
national algorithms would be available in similar form, this would serve 
a similar purpose.
 
FYI - I am interested in full details and some time last year I tried to 
download specs, but only Parts 2, 4, and 5 were available [1], [2], [3], 
not Parts 1 and 3.
 
Best regards, Rene
