<span class="h2"><a class="selflink" id="section-1" href="#section-1">1</a>.  Introduction</span>

   Russian cryptographic standards that define the algorithms GOST
   28147-89 [<a href="#ref-GOST28147" title="&quot;Cryptographic Protection for Data Processing System&quot;">GOST28147</a>], GOST R 34.10-94 [<a href="#ref-GOSTR341094" title="&quot;Information technology. Cryptographic Data Security. Produce and check procedures of Electronic Digital Signatures based on Asymmetric Cryptographic Algorithm.&quot;">GOSTR341094</a>], GOST R
   34.10-2001 [<a href="#ref-GOSTR341001" title="&quot;Information technology. Cryptographic data security. Signature and verification processes of [electronic] digital signature.&quot;">GOSTR341001</a>], and GOST R34.11-94 [<a href="#ref-GOSTR341194" title="&quot;Information technology. Cryptographic Data Security. Hashing function.&quot;">GOSTR341194</a>] provide
   basic information about how the algorithms work, but supplemental
   specifications are needed to effectively use the algorithms (a brief
   English technical description of these algorithms can be found in
   [<a href="#ref-Schneier95" title="second edition">Schneier95</a>]).

   This document is a proposal put forward by the CRYPTO-PRO Company to
   provide supplemental information and specifications needed by the
   "Russian Cryptographic Software Compatibility Agreement" community.

<span class="h3"><a class="selflink" id="section-1.1" href="#section-1.1">1.1</a>.  Terminology</span>

   In this document, the key words MUST, MUST NOT, REQUIRED, SHOULD,
   SHOULD NOT, RECOMMENDED, and MAY are to be interpreted as described
   in [<a href="./rfc2119">RFC2119</a>].

   The following functions and operators are also used in this document:

   '|' stands for concatenation.

   '~' stands for bitwise NOT operator.

   '^' stands for the power operator.

   encryptECB (K, D) is D, encrypted with key K using GOST 28147-89 in
   "prostaya zamena" (ECB) mode.

   decryptECB (K, D) is D, decrypted with key K using GOST 28147-89 in
   ECB mode.

   encryptCFB (IV, K, D) is D, encrypted with key K using GOST 28147-89
   in "gammirovanie s obratnoj svyaziyu" (64-bit CFB) mode, and IV is
   used as the initialization vector.

   encryptCNT (IV, K, D) is D, encrypted with key K using GOST 28147-89
   in "gammirovanie" (counter) mode, and IV is used as the
   initialization vector.

   gostR3411 (D) is the 256-bit result of the GOST R 34.11-94 hash
   function, used with zero initialization vector, and S-Box parameter,
   defined by id-GostR3411-94-CryptoProParamSet (see <a href="#section-11.2">Section 11.2</a>).

   gost28147IMIT (IV, K, D) is the 32-bit result of the GOST 28147-89 in
   "imitovstavka" (MAC) mode, used with D as plaintext, K as key and IV
   as initialization vector.  Note that the standard specifies its use
   in this mode only with an initialization vector of zero.

   When keys and initialization vectors are converted to/from byte
   arrays, little-endian byte order is assumed.

<span class="h2"><a class="selflink" id="section-2" href="#section-2">2</a>.  Cipher Modes and Parameters</span>

   This document defines four cipher properties that allow an
   implementer to vary cipher operations.  The four parameters are the
   cipher mode, the key meshing algorithm, the padding mode, and the
   S-box.

   [<a id="ref-GOST28147">GOST28147</a>] defines only three cipher modes for GOST 28147-89: ECB,
   CFB, and counter mode.  This document defines an additional cipher
   mode, CBC.







<span class="grey">Popov, et al.                Informational                      [Page 3]</span></pre>
<hr class='noprint'/><!--NewPage--><pre class='newpage'><span id="page-4" ></span>
<span class="grey"><a href="./rfc4357">RFC 4357</a>          Crypto-Pro Cryptographic Algorithms       January 2006</span>


   When GOST 28147-89 is used to process large amounts of data, a
   symmetric key should be protected by a key meshing algorithm.  Key
   meshing transforms a symmetric key after some amount of data has been
   processed.  This document defines the CryptoPro key meshing
   algorithm.

   The cipher mode, key meshing algorithm, padding mode, and S-box are
   specified by algorithm parameters.

<span class="h3"><a class="selflink" id="section-2.1" href="#section-2.1">2.1</a>.  GOST 28147-89 CBC Mode</span>

   This section provides the supplemental information for GOST 28147-89
   (a block-to-block primitive) needed to operate in CBC mode.

   Before each plaintext block is encrypted, it is combined with the
   cipher text of the previous block via a bitwise XOR operation.  This
   ensures that even if the plaintext contains many identical blocks,
   each block will encrypt to a different cipher text block.  The
   initialization vector is combined with the first plaintext block by a
   bitwise XOR operation before the block is encrypted.

<span class="h3"><a class="selflink" id="section-2.2" href="#section-2.2">2.2</a>.  GOST 28147-89 Padding Modes</span>

   This section provides the supplemental information for GOST 28147-89,
   needed to operate on plaintext where the length is not divisible by
   GOST 28147-89 block size (8 bytes).

   Let x (0 &lt; x &lt;= 8) be the number of bytes in the last, possibly
   incomplete, block of data.

   There are three padding modes:
    * Zero padding: 8-x remaining bytes are filled with zero
    * PKCS#5 padding: 8-x remaining bytes are filled with the value of
      8-x.  If there's no incomplete block, one extra block filled with
      value 8 is added.
    * Random padding: 8-x remaining bytes of the last block are set to
      random.

<span class="h3"><a class="selflink" id="section-2.3" href="#section-2.3">2.3</a>.  Key Meshing Algorithms</span>

   Key meshing algorithms transform the key after processing a certain
   amount of data.  In applications that must be strictly robust to
   attacks based on timing and EMI analysis, one symmetric key should
   not be used for quantities of plaintext larger than 1024 octets.

<span class="grey"><a href="./rfc4357">RFC 4357</a>          Crypto-Pro Cryptographic Algorithms       January 2006</span>


   A key meshing algorithm affects internal cipher state; it is not a
   protocol level feature.  Its role is similar to that of a cipher
   mode.  The choice of key meshing algorithm is usually dictated by the
   encryption algorithm parameters, but some protocols explicitly
   specify applicable key meshing algorithms.

   All encryption parameter sets defined in this document specify the
   use of the CryptoPro key meshing algorithm, except for id-Gost28147-
   89-TestParamSet, which specifies use of null key meshing algorithm.

<span class="h4"><a class="selflink" id="section-2.3.1" href="#section-2.3.1">2.3.1</a>.  Null Key Meshing</span>

   The null key meshing algorithm never changes a key.

   The identifier for this algorithm is:

       id-Gost28147-89-None-KeyMeshing OBJECT IDENTIFIER ::=
           { iso(1) member-body(2) ru(643) rans(2) cryptopro(2)
               keyMeshing(14) none(0) }

   There are no meaningful parameters to this algorithm.  If present,
   AlgorithmIdentifier.parameters MUST contain NULL.

<span class="h4"><a class="selflink" id="section-2.3.2" href="#section-2.3.2">2.3.2</a>.  CryptoPro Key Meshing</span>

   The CryptoPro key meshing algorithm transforms the key and
   initialization vector every 1024 octets (8192 bits, or 256 64-bit
   blocks) of plaintext data.

   This algorithm has the same drawback as OFB cipher mode: it is
   impossible to re-establish crypto synch while decrypting a ciphertext
   if parts of encrypted data are corrupted, lost, or processed out of
   order.  Furthermore, it is impossible to re-synch even if an IV for
   each data packet is provided explicitly.  Use of this algorithm in
   protocols such as IPsec ESP requires special care.

   The identifier for this algorithm is:

       id-Gost28147-89-CryptoPro-KeyMeshing  OBJECT IDENTIFIER ::=
           { iso(1) member-body(2) ru(643) rans(2) cryptopro(2)
               keyMeshing(14) cryptoPro(1) }

   There are no meaningful parameters to this algorithm.  If present,
   AlgorithmIdentifier.parameters MUST contain NULL.

   GOST 28147-89, in encrypt, decrypt, or MAC mode, starts with key K[0]
   =  K, IV0[0] = IV, i = 0.  Let IVn[0] be the value of the
   initialization vector after processing the first 1024 octets of data.



<span class="grey">Popov, et al.                Informational                      [Page 5]</span></pre>
<hr class='noprint'/><!--NewPage--><pre class='newpage'><span id="page-6" ></span>
<span class="grey"><a href="./rfc4357">RFC 4357</a>          Crypto-Pro Cryptographic Algorithms       January 2006</span>


   Processing of the next 1024 octets will start with K[1] and IV0[1],
   which are calculated using the following formula:

       K[i+1] = decryptECB (K[i], C);
       IV0[i+1] = encryptECB (K[i+1],IVn[i])

   Where C = {0x69, 0x00, 0x72, 0x22,   0x64, 0xC9, 0x04, 0x23,
              0x8D, 0x3A, 0xDB, 0x96,   0x46, 0xE9, 0x2A, 0xC4,
              0x18, 0xFE, 0xAC, 0x94,   0x00, 0xED, 0x07, 0x12,
              0xC0, 0x86, 0xDC, 0xC2,   0xEF, 0x4C, 0xA9, 0x2B};

   After processing each 1024 octets of data:
    * the resulting initialization vector is stored as IVn[i];
    * K[i+1] and IV0[i+1] are calculated;
    * i is incremented;
    * Encryption or decryption of next 1024 bytes starts, using
      the new key and IV;
   The process is repeated until all the data has been processed.

<span class="h2"><a class="selflink" id="section-3" href="#section-3">3</a>.  HMAC_GOSTR3411</span>

   HMAC_GOSTR3411 (K,text) function is based on the hash function GOST R
   34.11-94, as defined in [<a href="#ref-HMAC" title="&quot;HMAC: Keyed-Hashing for Message Authentication&quot;">HMAC</a>], with the following parameter values:
   B = 32, L = 32.

<span class="h2"><a class="selflink" id="section-4" href="#section-4">4</a>.  PRF_GOSTR3411</span>

   PRF_GOSTR3411 is a pseudorandom function, based on HMAC_GOSTR3411.
   It is calculated as P_hash, defined in Section 5 of [<a href="#ref-TLS" title="&quot;The TLS Protocol Version 1.0&quot;">TLS</a>].
   PRF_GOSTR3411(secret,label,seed) = P_GOSTR3411 (secret,label|seed).

   <a href="#section-5.1">Section 5.1</a> specifies algorithm VKO GOST R 34.10-94, which generates

   Keypairs MUST have identical parameters.

<span class="h3"><a class="selflink" id="section-5.1" href="#section-5.1">5.1</a>.  VKO GOST R 34.10-94</span>

   This algorithm creates a key encryption key (KEK) using the sender's
   private key and the recipient's public key (or vice versa).

<span class="grey"><a href="./rfc4357">RFC 4357</a>          Crypto-Pro Cryptographic Algorithms       January 2006</span>


   Exchange key KEK is a 256-bit hash of the 1024-bit shared secret that
   is generated using Diffie-Hellman key agreement.

   1) Let K(x,y) = a^(x*y) (mod p), where
      x - sender's private key, a^x - sender's public key

   Keypairs (x,a^x) and (y,a^y) MUST comply with [<a href="#ref-GOSTR341094" title="&quot;Information technology. Cryptographic Data Security. Produce and check procedures of Electronic Digital Signatures based on Asymmetric Cryptographic Algorithm.&quot;">GOSTR341094</a>].

   This algorithm MUST NOT be used when a^x = a (mod p) or a^y = a (mod
   p).

<span class="h3"><a class="selflink" id="section-5.2" href="#section-5.2">5.2</a>.  VKO GOST R 34.10-2001</span>

   This algorithm creates a key encryption key (KEK) using 64 bit UKM,

   reverse of the latter pair).

   1) Let K(x,y,UKM) = ((UKM*x)(mod q)) . (y.P) (512 bit), where

   Note: This algorithm MUST NOT be used with a KEK produced by VKO GOST
   R 34.10-94, because such a KEK is constant for every sender-recipient
   pair.  Encrypting many different content encryption keys on the same
   constant KEK may reveal that KEK.

   The GOST 28147-89 key wrap algorithm is:

    1) For a unique symmetric KEK, generate 8 octets at random and call
       the result UKM.  For a KEK, produced by VKO GOST R 34.10-2001,
       use the UKM that was used for key derivation.
    2) Compute a 4-byte checksum value, gost28147IMIT (UKM, KEK, CEK).
       Call the result CEK_MAC.
    3) Encrypt the CEK in ECB mode using the KEK.  Call the ciphertext
       CEK_ENC.
    4) The wrapped content-encryption key is (UKM | CEK_ENC | CEK_MAC).

   This algorithm decrypts GOST 28147-89 CEK with a GOST 28147-89 KEK.
   The GOST 28147-89 key unwrap algorithm is:

    1) If the wrapped content-encryption key is not 44 octets, then
       error.
    2) Decompose the wrapped content-encryption key into UKM, CEK_ENC,
       and CEK_MAC.  UKM is the most significant (first) 8 octets.
       CEK_ENC is next 32 octets, and CEK_MAC is the least significant
       (last) 4 octets.
    3) Decrypt CEK_ENC in ECB mode using the KEK.  Call the output CEK.
    4) Compute a 4-byte checksum value, gost28147IMIT (UKM, KEK, CEK),
       compare the result with CEK_MAC.  If they are not equal, then

<span class="h3"><a class="selflink" id="section-6.3" href="#section-6.3">6.3</a>.  CryptoPro Key Wrap</span>

   This algorithm encrypts GOST 28147-89 CEK with a GOST 28147-89 KEK.
   It can be used with any KEK (e.g., produced by VKO GOST R 34.10-94 or
   VKO GOST R 34.10-2001) because a unique UKM is used to diversify the
   KEK.

   The CryptoPro key wrap algorithm is:

    1) For a unique symmetric KEK or a KEK produced by VKO GOST R
       34.10-94, generate 8 octets at random.  Call the result UKM.  For
       a KEK, produced by VKO GOST R 34.10-2001, use the UKM that was
       used for key derivation.
    2) Diversify KEK, using the CryptoPro KEK Diversification Algorithm,
       described in <a href="#section-6.5">Section 6.5</a>.  Call the result KEK(UKM).

   Given a random 64-bit UKM and a GOST 28147-89 key K, this algorithm
   creates a new GOST 28147-89 key K(UKM).

    1) Let K[0] = K;
    2) UKM is split into components a[i,j]:
       UKM = a[0]|..|a[7] (a[i] - byte, a[i,0]..a[i,7] - it's bits)
    3) Let i be 0.
    4) K[1]..K[8] are calculated by repeating the following algorithm
       eight times:
     A) K[i] is split into components k[i,j]:
        K[i] = k[i,0]|k[i,1]|..|k[i,7] (k[i,j] - 32-bit integer)
     B) Vector S[i] is calculated:
        S[i] = ((a[i,0]*k[i,0] + ... + a[i,7]*k[i,7]) mod 2^32) |
        (((~a[i,0])*k[i,0] + ... + (~a[i,7])*k[i,7]) mod 2^32);

   This algorithm creates a GOST 28147-89 key Kd, given GOST R 34.10-94
   or GOST R 34.10-2001 secret key K and diversification data D of size
   4..40 bytes.

    1) 40-byte blob B is created from D by cloning it enough times to
       fill all 40 bytes.  For example, if D is 40-bytes long, B = D; If
       D is 6-bytes long, B = D|D|D|D|D|D|D[0..3].
    2) B is split into 8-byte UKM and 32-byte SRCKEY (B = UKM|SRCKEY).
    3) The algorithm from <a href="#section-6.5">Section 6.5</a> is used to create K(UKM) from key
       K and UKM, with two differences:
         * Instead of S[i], vector (0,0,0,UKM[i],ff,ff,ff,ff XOR UKM[i])
           is used.
         * During each encryption step, only 8 out of 32 GOST 28147-89

   Parameters here are given as SEQUENCE OF AlgorithmIdentifier in ASN.1
   DER encoding [<a href="#ref-X.660" title="Canonical Encoding Rules (CER) and Distinguished Encoding Rules (DER)">X.660</a>], stored in the same format as the examples in
   [<a href="./rfc4134" title="&quot;Examples of S/MIME Messages&quot;">RFC4134</a>], can be extracted using the same program.

   If you want to extract without the program, copy all the lines
   between the "|&gt;" and "|&lt;" markers, remove any page breaks, and remove
   the "|" in the first column of each line.  The result is a valid
   Base64 blob that can be processed by any Base64 decoder.
