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.
Shen & Lee Expires August 18, 2014 [Page 3]
Internet-Draft SM3 Hash function February 2014
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:
Shen & Lee Expires August 18, 2014 [Page 4]
Internet-Draft SM3 Hash function February 2014
ABCDEFGH < -- V(i)
FOR j=0 TO 63
SS1 < -- ((A SHIFT12) + E + (Tj SHIFTj))?7
SS2 < -- SS1 XOR (A SHIFT12)
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.
4. IANA Considerations
There is no iana related issue for this document.
5. Security Considerations
This document gives description of a cryptographic algorithm. Its
security properties are under public study. There are no known
feasible attacks against this algorithm by the time of publishing
this document.
