Internet-Draft              SM3 Hash function              February 2014


1.  Introduction

   The algorithm described in this document is published ([SM3]) by
   Chinese Commercial Cryptography Administration Office.  This document
   gives IETF standard description of these algorithms and parameters.

2.  Conventions Used in this Document

   The key words "MUST", "MUST NOT", "SHOULD", "SHOULD NOT", and "MAY"
   in this document are to be interpreted as defined in "Key words for
   use in RFCs to Indicate Requirement Levels" [RFC2119].

3.  Algorithm

   This chatper introduced the algorithm itself.  The content and
   structure strictly follow what is published by Chinese Commercial
   Cryptography Administration Office.

3.1.  Scope of SM3

   This document defines SM3 Hash algorithms and gives computing
   examples.  It can be used in commercial cryptography applicaitons
   like digital signature and verification, message authentication code
   and verification, random number generation.  This document can also
   be technical reference of security product and standards in order to
   improve the trustness and interoperability.

3.2.  Definitions and Terms


   Bit String  String composed of 0 and 1

   Big-endian  A format that describe the order in which data
               are stored in computer memory. It defines that
               the bytes with most significant value are stored
               at the left and bytes with least significant value
               are stored at the right. The high digits of a
               number are stored at high storage address and
               the low digits of a number are stored at low storage
               address.

   Message     Bit string with arbitary length. In this document a
               message is consider the input of the hash algorithm.

   Hash Value  The bit string which is the output after the hash algorithm
               applied to a message. The length of the hash value in this
               document is 256 bits.

   Word        A bit string with length 32.

3.3.  Symbols

3.3.1.  Iteration Precedure

   The procedures are: Divide he message m' after padding into 512 bits
   blocks:


      m~ = B(0)B(1) ... B(n-1)             where n=(l+k+65)/512

   Apply iteration operation to m' as following:


      FOR i=0 TO n-1
          V (i+1) = CF(V (i);B(i))
      ENDFOR

   where CF is compression function, V(0) is a 256 bits of IVAGBPA[not]
   B(i) is a message block after padding, the result after iterative
   compression is V(n).

3.3.2.  Message Extension

   Divide the message block B(i) into 132 words, apply the words into
   the compression function:


   a) divide message block B(i) into 16 words W0, W1, ... , W15.
   b)   FOR j=16 TO 67
        Wj  < --  P1(WAGBPA"j-16AGBPA(C) XOR WAGBPA"j-9AGBPA(C) XOR (WAGBPA"j-3AGBPA(C)SHIFT15))
                  XOR (WAGBPA"j-13AGBPA(C)SHIFT7)  XOR WAGBPA"j-6AGBPA(C)
      ENDFOR
   c)   FOR j=0 TO 63
        Wj~ = Wj XOR W(j+4)
      ENDFOR

3.3.3.  Compression function

   Let A,B,C,D,E,F,G,H be registers to store words; SS1, SS2, TT1 and
   TT2 be intermediate variable; compression function:


                   V(i+1) = CF(V(i);B(i))          where 0 A!U i A!U n

   The computation precedures are as following:

                   FOR j=0 TO 63

                           TT1  < --  FFj(A,B,C) + D + SS2 +Wj~
                           TT1  < --  GGj(E,F,G) + H + SS1 +Wj
                           D  < --  C
                           C  < --  B SHIFT9
                           B  < --  A
                           A  < --  TT1
                           H  < --  G
                           G  < --  F SHIFT19
                           F  < --  E
                           E  < --  P0(TT2)
                   ENDFOR
                   V(i+1)  < --  ABCDEFGH  XOR  V (i)

   where a word is stored in memory as big-endian format.

3.3.4.  Hash Value

   ABCDEFGH < -- V(n)

   The 256 bits of hash value is y=ABCDEFGH.
