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 22 September 2022 [Page 4] Internet-Draft GOST Password-based Keys March 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. 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.

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. - Compute MAC for the message M using the K(2) key. 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 Appendix A. 5.1.2. Decryption The decryption process for PBES2 consists of the following steps: 1.

Apply the key derivation function PBKDF2 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 = 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- kuznyechik-ctracpkm algorithms (see Appendix A.3) decrypt the ciphertext C with GOST R 34.12-2015 algorithm with the derived key DK and the random value S' to produce the message M. 5. For id-gostr3412-2015-magma-ctracpkm-omac and id-gostr3412-2015- kuznyechik-ctracpkm-omac algorithms (see Appendix A.3) decrypt the 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). 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. - 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. - Compute MAC for the text[1..m - k] using the K(2) key, where m is the size of text. Karelina Expires 22 September 2022 [Page 7] Internet-Draft GOST Password-based Keys March 2022 - 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. 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, ukm as algorithm parameters in accordance with Appendix A. 6.2. MAC Verification The MAC verification operation for PBMAC1 consists of the following steps: 1.

Process the message M with the underlying message authentication scheme with the derived key DK to generate a message authentication code MAC'. 5. 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. 7. Security Considerations This entire document is about security. For information on security considerations for password-based cryptography see [RFC8018]. Conforming applications MUST use unique values for ukm and S. It is RECOMMENDED to use the value of parameter c equal to 2000 for generating the derived key in PBKDF2 algorithm. It is RECOMMENDED to use the value of parameter S equal to 32 octets for generating the derived key in PBKDF2 algorithm. It is RECOMMENDED to use the exact algorithm parameters in symmetric algorithms "Magma" and "Kuznyechik". They are defined in Appendix A.3. 8.
