AFAIK, all the ISO standards that IETF refers to, were defined elsewhere first, i.e., ISO defined them based on some open submissions, publications, etc.

 

I fully agree with Rene – if you want the specs standardized, provide the complete specs, including the missing parts 1 and 3.

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,

 

Kind Regards

Kepeng

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
