Generating Password-based Password-Based Keys Using the GOST Algorithms
draft-pkcs5-gost-09
Abstract
This document specifies how to use the "PKCS #5: Password-Based
Cryptography Specification version 2.1 (PKCS #5) defined in RFC8018 Version 2.1" (RFC 8018) to generate a
symmetric key from a password in conjunction with the Russian
national standard GOST algorithms.
PKCS #5 applies a pseudorandom function (a Pseudorandom Function (PRF) -- a cryptographic
hash, cipher, or HMAC) Hash-Based Message Authentication Code (HMAC) -- to
the input password along with a salt value and repeats the process
many times to produce a derived key.
This specification is has been developed outside the IETF and is published IETF. The purpose
of publication being 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. here.

4. Algorithm For for Generating a Key From from a Password
The DK key is calculated by means of a key derivation function
PBKDF2(P, PBKDF2 (P,
S, c, dkLen) (see [RFC8018], section 5.2 Section 5.2) using the HMAC_GOSTR3411
function as the PRF pseudo-random function: PRF:
DK = PBKDF2(P,S,c,dkLen). 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 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)) (i)),
U_2(i) = HMAC_GOSTR3411 (P, U_1(i)) U_1(i)),
...
U_c(i) = HMAC_GOSTR3411 (P, U_{c-1}(i)) U_(c-1)(i)),
T(i) = U_1(i) \xor U_2(i) \xor ... \xor U_c(i) 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 MSB^(n * 64}_dkLen(T(1)||T(2)||...||T(n)) 64)_dkLen(T(1)||T(2)||...||T(n))

octets, i.e.,
DK = PBKDF2(P,S,c,32) 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, octets depending on the selected encryption algorithm:

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

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] ). (see
[RFC0020]). The sequence "\0" (without quotation marks) means a
literal ASCII NULL value (1 octet). "DK" refers to the Derived Key. derived key.

P = "password" (8 octets)
S = "salt" (4 octets)
