Generating Password-based Keys Using the GOST Algorithms
draft-pkcs5-gost-09
Abstract
This document specifies how to use the Password-Based Cryptography
Specification version 2.1 (PKCS #5) defined in RFC8018 to generate a
symmetric key from a password in conjunction with the Russian
national standard GOST algorithms.
PKCS #5 applies a pseudorandom function (a cryptographic hash,
cipher, or HMAC) to the input password along with a salt value and
repeats the process many times to produce a derived key.
This specification is developed outside the IETF and is published to
facilitate interoperable implementations that wish to support the
GOST algorithms. This document does not imply IETF endorsement of
the cryptographic algorithms used in this document.

4. Algorithm For Generating a Key From a Password
The DK key is calculated by means of a key derivation function
PBKDF2(P, S, c, dkLen) [RFC8018], section 5.2 using the
HMAC_GOSTR3411 function as the PRF pseudo-random function:
DK = PBKDF2(P,S,c,dkLen).
The PBKDF2 function is defined as the following algorithm:
1. If dkLen > (2^32 - 1) * 64, output "derived key too long" and
stop.
2. Calculate n = CEIL(dkLen / 64).
3. Calculate a set of values for each i from 1 to n:
U_1(i) = HMAC_GOSTR3411 (P, S || INT (i))
U_2(i) = HMAC_GOSTR3411 (P, U_1(i))
Karelina Expires 1 April 2023 [Page 4]
Internet-Draft GOST Password-based Keys September 2022
...
U_c(i) = HMAC_GOSTR3411 (P, U_{c-1}(i))
T(i) = U_1(i) \xor U_2(i) \xor ... \xor U_c(i)
4. Concatenate the octet strings T(i) and extract the first dkLen
octets to produce a derived key DK:
DK = MSB^{n * 64}_dkLen(T(1)||T(2)||...||T(n))
5. Data Encryption
5.1. GOST R 34.12-2015 Data Encryption
Data encryption using the DK key is carried out in accordance with
the PBES2 scheme (see [RFC8018], section 6.2) using GOST R 34.12-2015
in CTR_ACPKM mode (see [RFC8645]).
5.1.1. Encryption
The encryption process for PBES2 consists of the following steps:
1. Select the random value S of length from 8 to 32 octets.
2. Select the iteration count c depending on the conditions of use
(see [GostPkcs5]). The minimum allowable value for the parameter
is 1000.
3. Set the value dkLen = 32.
4. Apply the key derivation function to the password P, the random
value S and the iteration count c to produce a derived key DK of
length dkLen octets in accordance with the algorithm from
Section 4. Generate the sequence T(1) and truncate it to 32
octets, i.e.,
DK = PBKDF2(P,S,c,32) = MSB^64_32(T(1)).
5. Generate the random value ukm of size n, where n takes a value of
12 or 16 octets, depending on the selected encryption algorithm:
GOST R 34.12-2015 "Kuznyechik" n = 16 (see [RFC7801])
GOST R 34.12-2015 "Magma" n = 12 (see [RFC8891])
6. Set the value S' = ukm[1..n-8]

7. For id-gostr3412-2015-magma-ctracpkm and id-gostr3412-2015-
kuznyechik-ctracpkm algorithms (see Section 7.3) encrypt the
message M with GOST R 34.12-2015 algorithm with the derived key
DK and the random value S' to produce a ciphertext C.
8. For id-gostr3412-2015-magma-ctracpkm-omac and id-gostr3412-2015-
kuznyechik-ctracpkm-omac algorithms (see Section 7.3) encrypt the
message M with GOST R 34.12-2015 algorithm with the derived key
DK and the ukm in accordance with the following steps:
- Generate two keys from the derived key DK using the
KDF_TREE_GOSTR3411_2012_256 algorithm (see [RFC7836]):
encryption key K(1)
MAC key K(2).
Input parameters for the KDF_TREE_GOSTR3411_2012_256 algorithm
take the folowing values:
K_in = DK
label = "kdf tree" (8 octets)
seed = ukm[n-7..n]
R = 1
The input string label above is encoded using ASCII (
[RFC0020] ).
- Compute MAC for the message M using the K(2) key in
accordance with GOST R 34.12-2015 algorithm. Append the
computed MAC value to the message M: M||MAC.
- Encrypt the resulting octet string with MAC with GOST R
34.12-2015 algorithm with the derived key K(1) and the random
value S' to produce a ciphertext C.
9. Serialize the parameters S, c, ukm as algorithm parameters in
accordance with Section 7.2.
5.1.2. Decryption
The decryption process for PBES2 consists of the following steps:

random value S and the iteration count c to produce a derived key
DK of length dkLen octets in accordance with the algorithm from
Section 4. Generate the sequence T(1) and truncate it to 32
octets, i.e., DK = PBKFD2(P,S,c,32) = MSB^64_32(T(1)).
3. Set the value S' = ukm[1..n-8], where n is the size of ukm in
octets.
4. For id-gostr3412-2015-magma-ctracpkm and id-gostr3412-2015-

ciphertext C with GOST R 34.12-2015 algorithm with the derived
key DK and the random value S' to produce the message M.

ciphertext C with GOST R 34.12-2015 algorithm with the derived
key DK and the ukm in accordance with the following steps:
- Generate two keys from the derived key DK using the
KDF_TREE_GOSTR3411_2012_256 algorithm:
encryption key K(1)
MAC key K(2).

take the folowing values:
K_in = DK
label = "kdf tree" (8 octets)
seed = ukm[n-7..n]
R = 1
The input string label above is encoded using ASCII (
[RFC0020] ).
- Decrypt the ciphertext C with GOST R 34.12-2015 algorithm
with the derived key K(1) and the random value S' to produce
the plaintext. The last k octets of the text are the message
authentication code MAC', where k depends on the selected
encryption algorithm.
Karelina Expires 1 April 2023 [Page 7]
Internet-Draft GOST Password-based Keys September 2022
- Compute MAC for the text[1..m - k] using the K(2) key in
accordance with GOST R 34.12-2015 algorithm, where m is the
size of text.
- Compare the original message authentication code MAC and the
receiving message authentication code MAC'. If the sizes or
values do not match, the message is distorted.
6. Message Authentication
PBMAC1 scheme is used for message authentication (see [RFC8018],
section 7.1). This scheme bases on the HMAC_GOSTR3411 function.
6.1. MAC Generation
The MAC generation operation for PBMAC1 consists of the following
steps:
1. Select the random value S of length from 8 to 32 octets.
2. Select the iteration count c depending on the conditions of use
(see [GostPkcs5]). The minimum allowable value for the parameter
is 1000.
3. Set the dkLen to at least 32 octets. It depends on previous
parameter values.
4. Apply the key derivation function to the password P, the random
value S and the iteration count c to generate a sequence K of
length dkLen octets in accordance with the algorithm from
Section 4.
5. Truncate the sequence K to 32 octets to get the derived key DK,
i.e., DK = LSB^dkLen_32(K).
6. Process the message M with the underlying message authentication
scheme with the derived key DK to generate a message
authentication code T.
7. Save the parameters S, c as algorithm parameters in accordance
with Section 7.4.
6.2. MAC Verification

It is RECOMMENDED that parameter S consist of at least 32 octets of
pseudo-random data in order to reduce the probability of collisions
of keys generated from the same password.
9. IANA Considerations

Appendix A. PBKDF2 HMAC_GOSTR3411 Test Vectors
These test vectors are formed by analogy with test vectors from
[RFC6070]. The input strings below are encoded using ASCII (
[RFC0020] ). The sequence "\0" (without quotation marks) means a
literal ASCII NULL value (1 octet). "DK" refers to the Derived Key.
