Re: [Cfrg] Recent SM2 and SM3 drafts update

Hi Shen,

Very interesting work.  It is good to see more curves appearing.  Thank you very much for publishing.  A couple small questions.

Is there a licensing statement associated with the submittal?
http://www.google.com/patents/CN102104481A?cl=en

When you say public below, I assume this statement means the work is being placed into the public domain.
Yes?


Thanks in advance,

Paul

Subject: [Cfrg] Recent SM2 and SM3 drafts update

Dear cryptographers in CFRG,
I have been working on writing a few cryptographic algorithms documents: SM2 elliptic curve digital signature algorithm and SM3 hash function. The two algorithms are published in China for years and required to be used in IT systems like electronic authentication service system.
It was my pleasure to provide the IETF documents to make these algorithms public to IETF community and hence the whole Internet industry. The two documents have been in published for quite a while and I updated a few versions. I also have given presentations in IETF meetings a few times to security guys in CFRG. Audience has been very interested in them.
I think these works are valuable to both IETF community and vendors in Chinese market. So I hope the two documents on the track to be IETF RFCs.
Also I prepared a simple webpage to give information (related documents and implementations) of a few crypto algorithms used in China, including SM2 and SM3. I will keep updating the draft and webpage , hope they are helpful to the community. Please check:

I will appreciate and reviews and suggestions.

Abstract:

   This document discribles a set of public key cryptographic algorithms

   based on elliptic curves which is invented by Xiaoyun Wang et al.

   These algorithms and recommended parameters are published by Chinese

   Commercial Cryptography Administration Office ([SM2 Algorithms] and

   [SM2 Algorithms Parameters]) for the use of electronic authentication

   service system.  This document gives IETF standard description of the

   algorithms and parameters in [SM2 Algorithms] and [SM2 Algorithms

   Parameters].



   The document [SM2 Algorithms] published by Chinese Commercial

   Cryptography Administration Office includes four parts: general

   introdocution, Digital Signature Algorithm, Key Exchange Protocol and

   Public Key Encryption Algorithm.



   The document [SM2 Algorithms Parameters] gives a set of recommended

   parameters.
