1. Introduction
This document specifies three new cipher suites, two new signature
algorithms, seven new supported groups and two new certificate types
for the Transport Layer Security (TLS) Protocol Version 1.2 [RFC5246]
to support the set of Russian cryptographic standard algorithms
(called GOST algorithms). This document specifies a profile of TLS
1.2 with GOST algorithms so that implementers can produce
interoperable implementations. The profile of TLS 1.2 with GOST
algorithms uses the hash algorithm GOST R 34.11-2012 [RFC6986] and
the signature algorithm GOST R 34.10-2012 [RFC7091] and use two types
of cipher suites: the CTR_OMAC cipher suites and the CNT_IMIT cipher
suite.
Smyshlyaev, et al. Expires 11 May 2022 [Page 3]
Internet-Draft GOST Cipher Suites for TLS 1.2 November 2021
The CTR_OMAC cipher suites use the GOST R 34.12-2015 (see [RFC7801],
[RFC8891]) block ciphers.
The CNT_IMIT cipher suite uses the GOST 28147-89 [RFC5830] block
cipher.
This document specifies the profile of the TLS protocol version 1.2
with GOST algorithms. The profile of the TLS protocol version 1.3
[RFC8446] with GOST algorithms is specified in a separate document
[DraftGostTLS13].
This specification is developed to facilitate implementations that
wish to support the GOST algorithms. This document does not imply
IETF endorsement of the cipher suites, signature algorithms,
supported groups and certificate types.

3. Basic Terms and Definitions
This document uses the following terms and definitions for the sets
and operations on the elements of these sets:
B_t the set of byte strings of length t, t >= 0, for t = 0 the
B_t set consists of a single empty string of zero length. If
A is an element of B_t, then A = (a_1, a_2, ... , a_t), where

C;
A XOR C bitwise exclusive-or of byte strings A and C both belonging

Internet-Draft GOST Cipher Suites for TLS 1.2 November 2021
to B_t (i.e. both are of length t bytes), i.e., a string in
B_t such that if A = (a_1, a_2, ... , a_t), C = (c_1, c_2,
... , c_t) then A XOR C = (a_1 (xor) c_1, a_2 (xor) c_2, ...
, a_t (xor) c_t) where (xor) is bitwise exclusive-or of
bytes;
i & j bitwise AND of unsigned integers i and j;

a byte string in big-endian format);
str_t the transformation that maps an integer i = 256^{t-1} * i_t +
... + 256 * i_2 + i_1 into the byte string str_t(i) = (i_1,
... , i_t) in B_t (the interpretation of the integer as a
byte string in little-endian format);
INT the transformation that maps a string a = (a_1, ... , a_t) in
B_t into the integer INT(a) = 256^{t-1} * a_1 + ... + 256 *
a_{t-1} + a_t (the interpretation of the byte string in big-
endian format as an integer);
int the transformation that maps a string a = (a_1, ... , a_t) in
B_t into the integer int(a) = 256^{t-1} * a_t + ... + 256 *

Internet-Draft GOST Cipher Suites for TLS 1.2 November 2021
r_s the random string contained in ServerHello.random field (see
[RFC5246]).
4. Cipher Suite Definitions
This document specifies the CTR_OMAC cipher suites and the CNT_IMIT
cipher suite.
The CTR_OMAC cipher suites have the following values:
TLS_GOSTR341112_256_WITH_KUZNYECHIK_CTR_OMAC = {0xC1, 0x00};
TLS_GOSTR341112_256_WITH_MAGMA_CTR_OMAC = {0xC1, 0x01}.
The CNT_IMIT cipher suite has the following value:
TLS_GOSTR341112_256_WITH_28147_CNT_IMIT = {0xC1, 0x02}.
4.1. Record Payload Protection
The profile of TLS 1.2 with GOST algorithms requires that the
compression is not used.
All of the cipher suites described in this document use such modes of
operation (see Section 4.3.3) that protect the records in the same
way as if they were protected by a stream cipher. The TLSCiphertext
structure for the CTR_OMAC and CNT_IMIT cipher suites is specified in
accordance with the Standard Stream Cipher case (see Section 6.2.3.1
of [RFC5246]):
struct {
ContentType type;
ProtocolVersion version;
uint16 length;
GenericStreamCipher fragment;
} TLSCiphertext;
where TLSCiphertext.fragment is generated in accordance with
Section 4.1.1 when the CTR_OMAC cipher suite is used and
Section 4.1.2 when the CNT_IMIT cipher suite is used.
Smyshlyaev, et al. Expires 11 May 2022 [Page 6]
Internet-Draft GOST Cipher Suites for TLS 1.2 November 2021
The connection key material is a key material that consists of the
sender_write_key (either the client_write_key or the
server_write_key), the sender_write_MAC_key (either the
client_write_MAC_key or the server_write_MAC_key) and the
sender_write_IV (either the client_write_IV or the server_write_IV)
parameters that are generated in accordance with Section 6.3 of
[RFC5246].
The record key material is a key material that is generated from the
connection key material and is used to protect a record with the
certain sequence number. Note that with some cipher suites defined
in this document the record key material can be equal to the
connection key material.
In this section the TLSCiphertext.fragment generation is described
for one particular endpoint (server or client) with the corresponding
connection key material and record key material.
4.1.1. CTR_OMAC
In case of the CTR_OMAC cipher suites the record key material differs
from the connection key material, and for the sequence number seqnum
consists of:
* K_ENC_seqnum in B_k;
* K_MAC_seqnum in B_k;
* IV_seqnum in B_{n/2}.
The K_ENC_seqnum and K_MAC_seqnum values are calculated using the
TLSTREE function defined in Section 8.1, the connection key material
and the sequence number seqnum. IV_seqnum is calculated by adding
seqnum value to sender_write_IV modulo 2^{(n/2)*8}:
* K_ENC_seqnum = TLSTREE(sender_write_key, seqnum);
* K_MAC_seqnum = TLSTREE(sender_write_MAC_key, seqnum);
* IV_seqnum = STR_{n/2}((INT(sender_write_IV) + seqnum) mod
2^{(n/2)*8}).
The TLSCiphertext.fragment that corresponds to the seqnum sequence
number is calculated as follows:
1. The MACValue_seqnum value is generated using the MAC algorithm
(see Section 4.3.2) similar to Section 6.2.3.1 of [RFC5246] except
the sender_write_MAC_key is replaced by the K_MAC_seqnum key:
Smyshlyaev, et al. Expires 11 May 2022 [Page 7]
Internet-Draft GOST Cipher Suites for TLS 1.2 November 2021
MACValue_seqnum = MAC(K_MAC_seqnum, STR_8(seqnum) | type_seqnum |
version_seqnum | length_seqnum | fragment_seqnum),
where type_seqnum, version_seqnum, length_seqnum, fragment_seqnum are
the TLSCompressed.type, TLSCompressed.version, TLSCompressed.length
and TLSCompressed.fragment values of the record with the seqnum
sequence number.
2. The entire data with the MACValue is encrypted with the ENC
stream cipher (see Section 4.3.3):
ENCValue_seqnum = ENC(K_ENC_seqnum, IV_seqnum, fragment_seqnum |
MACValue_seqnum),
where fragment_seqnum is the TLSCompressed.fragment value of the
record with the seqnum sequence number.
3. The fields of the GenericStreamCipher structure (see section
6.2.3.1 of [RFC5246]) for the TLSCiphertext.fragment value are
defined by the ENCValue_seqnum value:
TLSCiphertext.fragment.content =
ENCValue_seqnum[1..length_seqnum],
TLSCiphertext.fragment.MAC = ENCValue_seqnum[length_seqnum +
1..length_seqnum + mac_length],
where length_seqnum is the TLSCompressed.length value of the record
with the seqnum sequence number, mac_length is equal to 16 for the
TLS_GOSTR341112_256_WITH_KUZNYECHIK_CTR_OMAC cipher suite and 8 for
the TLS_GOSTR341112_256_WITH_MAGMA_CTR_OMAC cipher suite.
Note that the CTR_OMAC cipher suites use the authenticate-then-
encrypt method (see Appendix F.4 of [RFC5246]). Since these ciphers
are functioning as stream ciphers, the authenticate-then-encrypt
method is secure, and, as specified by [RFC7366], the server that
selects the CTR_OMAC ciphers MUST NOT send an encrypt_then_mac
extension to the client.
4.1.2. CNT_IMIT
In case of the CNT_IMIT cipher suite the record key material is equal
to the connection key material and consists of:
* sender_write_key in B_k;
* sender_write_MAC_key in B_k;
Smyshlyaev, et al. Expires 11 May 2022 [Page 8]
Internet-Draft GOST Cipher Suites for TLS 1.2 November 2021
* sender_write_IV in B_n.
The TLSCiphertext.fragment that corresponds to the seqnum sequence
number is calculated as follows:
1. The MACValue_seqnum value is generated by the MAC algorithm (see
Section 4.3.2) as follows:
MACValue_seqnum = MAC(sender_write_MAC_key, STR_8(0) | type_0 |
version_0 | length_0 | fragment_0 | ... | STR_8(seqnum) |
type_seqnum | version_seqnum | length_seqnum | fragment_seqnum),
where type_i, version_i, length_i, fragment_i, i in {0, ... ,
seqnum}, are the TLSCompressed.type, TLSCompressed.version,
TLSCompressed.length and TLSCompressed.fragment values of the record
with the i sequence number.
Due to the use of the CBC-MAC based mode (see Section 4.3.2)
producing the MACValue_seqnum value does not mean processing all
previous records. It is enough to store only an intermediate
internal state of the MAC algorithm.
2. The entire data with the MACValue is encrypted with the ENC
stream cipher (see Section 4.3.3):
ENCValue_0 | ... | ENCValue_seqnum = ENC(sender_write_key,
sender_write_IV, fragment_0 | MACValue_0 | ... | fragment_seqnum |
MACValue_seqnum),
where the length of the byte string ENCValue_i in bytes is equal to
the length of the byte string (fragment_i | MACValue_i) in bytes, i
in {0, ... , seqnum}.
Due to the use of the stream cipher (see Section 4.3.3) producing the
ENCValue_seqnum value does not mean processing all previous records.
It is enough to store only an intermediate internal state of the ENC
stream cipher.
3. The fields of the GenericStreamCipher structure (see section
6.2.3.1 of [RFC5246]) for the TLSCiphertext.fragment value are
defined by the ENCValue_seqnum value:
TLSCiphertext.fragment.content =
ENCValue_seqnum[1..length_seqnum],
TLSCiphertext.fragment.MAC = ENCValue_seqnum[length_seqnum +
1..length_seqnum + mac_length],
Smyshlyaev, et al. Expires 11 May 2022 [Page 9]
Internet-Draft GOST Cipher Suites for TLS 1.2 November 2021
where length_seqnum is the TLSCompressed.length value of the record
with the seqnum sequence number, mac_length is equal to 4.
Note that the CNT_IMIT cipher suite uses the authenticate-then-
encrypt method (see Appendix F.4 of [RFC5246]). Since this cipher is
functioning as a stream cipher, the authenticate-then-encrypt method
is secure, and, as specified by [RFC7366], the server that selects
the CNT_IMIT cipher MUST NOT send an encrypt_then_mac extension to
the client.
4.2. Key Exchange and Authentication
The cipher suites defined in this document use a key encapsulation
mechanism based on Diffie-Hellman to share the TLS premaster secret.

Note: To help avoid pipeline stalls, ChangeCipherSpec is an
independent TLS protocol content type, and is not actually
a TLS handshake message.
Figure 1 shows all messages involved in the TLS key establishment
protocol (full handshake). A ServerKeyExchange MUST NOT be sent (the
server's certificate contains enough data to allow client to exchange
the premaster secret).
Smyshlyaev, et al. Expires 11 May 2022 [Page 10]
Internet-Draft GOST Cipher Suites for TLS 1.2 November 2021
The server side of the channel is always authenticated; the client
side is optionally authenticated. The server is authenticated by
proving that it knows the premaster secret that is encrypted with the
public key Q_s from the server's certificate. The client is
authenticated via its signature over the handshake transcript.
In general the key exchange process for both CTR_OMAC and CNT_IMIT
cipher suites consists of the following steps:
1. The client generates the ephemeral key pair (d_eph, Q_eph) that
corresponds to the server's public key Q_s stored in its
certificate.
2. The client generates the premaster secret PS. The PS value is
chosen from B_32 at random.
3. Using d_eph and Q_s the client generates the export key material
(see Section 4.2.4.1 and Section 4.2.4.2) for the particular key
export algorithm (see Section 8.2.1 and Section 8.2.2) to
generate the export representation PSExp of the PS value.
4. The client sends its ephemeral public key Q_eph and PSExp value
in the ClientKeyExchange message.
5. Using its private key d_s the server generates the import key
material (see Section 4.2.4.1 and Section 4.2.4.2) for the
particular key import algorithm (see Section 8.2.1 and
Section 8.2.2) to extract the premaster secret PS from the export
representation PSExp.
This section specifies the data structures and computations used by
the profile of TLS 1.2 with GOST algorithms. The specifications for
the ClientHello, ServerHello, server Certificate, CertificateRequest,
ClientKeyExchange, CertificateVerify and Finished handshake messages
are described in further detail below.
4.2.1. Hello Messages
The ClientHello message is generated in accordance with
Section 7.4.1.2 of [RFC5246] and must meet the following
requirements:
* The ClientHello.compression_methods field MUST contain exactly one
byte, set to zero, which corresponds to the "null" compression
method.
* The ClientHello.extensions field MUST contain the
signature_algorithms extension (see [RFC5246]).
Smyshlyaev, et al. Expires 11 May 2022 [Page 11]
Internet-Draft GOST Cipher Suites for TLS 1.2 November 2021
If the negotiated cipher suite is one of CTR_OMAC/CTR_IMIT and the
signature_algorithms extension in the ClientHello message does not
contain the values defined in Section 5, the server MUST either
abort the connection or ignore this extension and behave as if the
client had sent the signature_algorithms extension with the values
{8, 64} and {8, 65}.
The ServerHello message is generated in accordance with
Section 7.4.1.3 of [RFC5246] and must meet the following
requirements:
* The ServerHello.compression_method field MUST contain exactly one
byte, set to zero, which corresponds to the "null" compression
method.
* The ServerHello.extensions field MUST NOT contain the
encrypt_then_mac extension (see [RFC7366]).
4.2.2. Server Certificate
This message is used to authentically convey the server's public key
Q_s to the client and is generated in accordance with Section 7.4.2
of [RFC5246].
Upon receiving this message the client validates the certificate
chain, extracts the server's public key, and checks that the key type
is appropriate for the negotiated key exchange algorithm. (A
possible reason for a fatal handshake failure is that the client's
capabilities for handling elliptic curves and point formats are
exceeded).
4.2.3. CertificateRequest
This message is sent by the server when requesting client
authentication and is generated in accordance with Section 7.4.4 of

The cipher suite TLS_GOSTR341112_256_WITH_KUZNYECHIK_CTR_OMAC MUST
use Kuznyechik [RFC7801] as a base block cipher for the encryption
and MAC algorithm. The block length n is 16 bytes and the key length

The CNT_IMIT cipher suite uses the block cipher in counter encryption
mode (CNT) defined in Section 6 of [RFC5830] with the CryptoPro Key
Meshing algorithm defined in [RFC4357] as the ENC function.
Note that the counter modes used in cipher suites described in this
document act as stream ciphers.
4.3.4. PRF and HASH algorithms
The pseudorandom function (PRF) for all the cipher suites defined in
this document is the PRF_TLS_GOSTR3411_2012_256 function defined in

5. New Values for the SignatureAlgorithm Registry
The signature/hash algorithm pairs are used to indicate to the
server/client which algorithms can be used in digital signatures and
are defined by the SignatureAndHashAlgorithm structure (see
Section 7.4.1.4.1 of [RFC5246]).
Smyshlyaev, et al. Expires 11 May 2022 [Page 19]
Internet-Draft GOST Cipher Suites for TLS 1.2 November 2021
This document defines new values for the "SignatureAlgorithm
Registry" that can be used in the SignatureAndHashAlgorithm.signature
field for the particular signature/hash algorithm pair:
enum {
gostr34102012_256(64),
gostr34102012_512(65),
} SignatureAlgorithm;
where the gostr34102012_256 and gostr34102012_512 values correspond
to the GOST R 34.10-2012 [RFC7091] signature algorithm with 32-byte
(256-bit) and 64-byte (512-bit) key length respectively.
According to [RFC7091] the GOST R 34.10-2012 signature algorithm with
32-byte (256-bit) or 64-byte (512-bit) key length use the GOST R
34.11-2012 [RFC6986] hash algorithm with 32-byte (256-bit) or 64-byte
(512-bit) hash code respectively (the hash algorithm is intrinsic to
the signature algorithm). Therefore, if the
SignatureAndHashAlgorithm.signature field of a particular hash/
signature pair listed in the Signature Algorithms Extension is equal
to the 64 (gostr34102012_256) or 65 (gostr34102012_512) value, the
SignatureAndHashAlgorithm.hash field of this pair MUST contain the
"Intrinsic" value 8 (see [RFC8422]).
So, to represent gostr34102012_256 and gostr34102012_512 in the
signature_algorithms extension, the value shall be (8,64) and (8,65),
respectively.
6. New Values for the Supported Groups Registry
The Supported Groups Extension indicates the set of elliptic curves
supported by the client and is defined in [RFC8422] and [RFC7919].

7. New Values for the ClientCertificateType Identifiers Registry
The ClientCertificateType field of the CertificateRequest message
contains a list of the types of certificate types that the client may

This document defines new values for the "ClientCertificateType
Identifiers" registry:
enum {
gost_sign256(67),
gost_sign512(68),
} ClientCertificateType;
To use the gost_sign256 or gost_sign512 authentication mechanism, the
client MUST possess a certificate containing a GOST R
34.10-2012-capable public key that corresponds to the 32-byte
(256-bit) or 64-byte (512-bit) signature key respectively.
The client proves possession of the private key corresponding to the
certified key by including a signature in the CertificateVerify

(see Section 8.1.1);
* KDF_j(K, D), j = 1, 2, 3, K in B_32, D in B_8, is the key
derivation function based on the KDF_GOSTR3411_2012_256 function
defined in [RFC7836]:
KDF_1(K, D) = KDF_GOSTR3411_2012_256(K, "level1", D);
KDF_2(K, D) = KDF_GOSTR3411_2012_256(K, "level2", D);
KDF_3(K, D) = KDF_GOSTR3411_2012_256(K, "level3", D).

| 4. seed = H[17..24] |
| 5. return KDFTREE_256(K_EXP, "kdf tree", seed, 1) |
+----------------------------------------------------------------+
where VKO_256 is the function VKO_GOSTR3410_2012_256 defined in
[RFC7836] and KDFTREE_256 is the KDF_TREE_GOSTR3411_2012_256 function
defined in [RFC7836] with the parameter L equal to 512.
The KEG_512 algorithm is defined as follows:
Smyshlyaev, et al. Expires 11 May 2022 [Page 26]
Internet-Draft GOST Cipher Suites for TLS 1.2 November 2021
+----------------------------------------------------------------+
| KEG_512(d, Q, H) |
|----------------------------------------------------------------|
| Input: |
| - private key d, |
| - public key Q, |
| - H in B_32. |
| Output: |
| - key material K in B_64. |
|----------------------------------------------------------------|
| 1. r = INT(H[1..16]) |
| 2. If r = 0 |
| UKM = 1; else UKM = r |
| 3. return VKO_512(d, Q, UKM) |
+----------------------------------------------------------------+
where VKO_512 is the VKO_GOSTR3410_2012_512 function defined in
[RFC7836].
8.3.2. KEG_28147 Algorithm
The KEG_28147 algorithm is defined as follows:
+----------------------------------------------------------------+
| KEG_28147(d, Q, H) |
|----------------------------------------------------------------|
| Input: |
| - private key d, |
| - public key Q, |
| - H in B_32. |
| Output: |
| - key material K in B_32. |
|----------------------------------------------------------------|
| 1. If q * Q is not equal to zero point |
| return FAIL |
| 2. UKM = H[1..8] |
| 3. R = VKO_256(d, Q, int(UKM)) |
| 4. return K = CPDivers(UKM, R) |
+----------------------------------------------------------------+
where the VKO_256 function is equal to the VKO_GOSTR3410_2012_256
function defined in [RFC7836], the CPDivers function corresponds to
the CryptoPro KEK Diversification Algorithm defined in [RFC4357],
which takes as input the UKM value and the key value.

8.4. gostIMIT28147
gost28147IMIT(IV, K, M) is a MAC algorithm with 4 bytes output and is
defined as follows:
+----------------------------------------------------------------+
| gost28147IMIT(IV, K, M) |
|----------------------------------------------------------------|
| Input: |
| - initial value IV in B_8, |
| - key K in B_32, |
| - message M in B*. |
| Output: |
| - MAC value T in B_4. |
|----------------------------------------------------------------|
| 1. M' = PAD(M) |
| 2. M' = M'_0 | ... | M'_r, L(M'_i) = 8, i in {0, ... , r} |
| 3. M'' = (M'_0 XOR IV) | M'_1 | ... | M'_r |
| 4. return T = MAC28147(K, M'') |
+----------------------------------------------------------------+
where the PAD function is the padding function that adds m zero bytes
to the end of the message, where m is the smallest, non-negative
solution to the equation (L(M) + m) mod 8 = 0, the MAC28147 function
corresponds to Message Authentication Code Generation Mode defined in
[RFC5830] with 4 byte length output.

allocated from the Reserved state due to a misunderstanding of the
difference between Reserved and Unallocated that went undetected for
a long time. Additional allocations from the Reserved state are not
expected, and the TLS SignatureScheme registry is suitable for use
for new allocations instead of this registry".
IANA has added numbers 34, 35, 36, 37, 38, 39, 40 with the names

10. Historical Considerations
Note that prior to the existence of this document implementations
could use only the values from the Private Use space in order to use
the GOST-based algorithms. So some old implementations can still use
the old value {0xFF, 0x85} instead of the {0xC1, 0x02} value to
indicate the TLS_GOSTR341112_256_WITH_28147_CNT_IMIT cipher suite;
one old value 0xEE instead of the values 64, 8 and 67 (to indicate
the gostr34102012_256 signature algorithm, the Intrinsic hash
algorithm and the gost_sign256 certificate type respectively); one
old value 0xEF instead of the values 65, 8 and 68 (to indicate the
gostr34102012_512 signature algorithm, the Intrinsic hash algorithm
and the gost_sign512 certificate type respectively).
Due to historical reasons in addition to the curve identifier values
listed in Table 2 there exist some extra identifier values that
correspond to the curves GC256B, GC256C and GC256D as follows (see
[RFC4357], [R-1323565.1.024-2019]).
+-------------+-----------------------------------------+
| Description | Curve Identifier Values |
+-------------+-----------------------------------------+
| GC256B |id-GostR3410_2001-CryptoPro-XchA-ParamSet|
| |id-tc26-gost-3410-2012-256-paramSetB |
+-------------+-----------------------------------------+
| GC256C |id-tc26-gost-3410-2012-256-paramSetC |
+-------------+-----------------------------------------+
| GC256D |id-GostR3410-2001-CryptoPro-XchB-ParamSet|
| |id-tc26-gost-3410-2012-256-paramSetD |

Table 9
Client should be prepared to handle any of them correctly if
corresponding group is included in the supported_groups extension
(see [RFC8422] and [RFC7919]).
11. Security Considerations
The cipher suites defined in this document do not provide Perfect
Forward Secrecy.
The authenticate-then-encrypt method is crucial for the CNT_IMIT
cipher suite. Encryption of the MAC value is conducted to reduce the
possibility of forgery to guessing. Here the probability of guess is
approximately equal to 2^{-32}, which is acceptable in some practical
cases.
