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 [RFC 5246] (note that [RFC 5246] has been obsoleted by [RFC 8446] ) 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 [RFC 6986], the signature algorithm GOST R 34.10-2012 [RFC 7091], and two types of cipher suites: the CTR_OMAC and the CNT_IMIT.
The CTR_OMAC cipher suites use the GOST R 34.12-2015 (see [RFC 7801] and [RFC 8891]) block ciphers.
The CNT_IMIT cipher suite uses the GOST 28147-89 [RFC 5830] 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 [RFC 8446] with GOST algorithms is specified in a separate document [DraftGostTLS13].
This specification facilitates implementations that aim 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 follows the terminology from [RFC8446bis] for "preliminary secret" and "extended_main_secret".
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 a_1, a_2, ... , a_t are in {0, ... , 255}.

A XOR C
bitwise exclusive-or of byte strings A and C both belonging to B_t (both are of length t bytes), i.e., a string in B_t such that if A = (a_1, a_2, ... , a_t) and 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.
STR_t
the transformation that maps an integer i = 256t-1 * i_1 + ... + 256 * i_{t-1} + i_t into the byte string STR_t(i) = (i_1, ... , i_t) in B_t (the interpretation of the integer as a byte string in big-endian format).
str_t
the transformation that maps an integer i = 256t-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

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 not be 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 RFC 5246):
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 suites are used and Section 4.1.2 when the CNT_IMIT cipher suite is used.
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 RFC 5246.
The record key material is a key material that is generated from the connection key material and is used to protect a record with a 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 the CTR_OMAC cipher suites, the record key material differs from the connection key material, and for the seqnum sequence number consists of:
K_ENC_seqnum in B_k;

K_MAC_seqnum in B_k; and

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 seqnum sequence number . IV_seqnum is calculated by adding the 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); and

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 Message Authentication Code (MAC) algorithm (see Section 4.3.2) similar to Section 6.2.3.1 of RFC 5246, except the sender_write_MAC_key is replaced by the K_MAC_seqnum key:
    MACValue_seqnum = MAC(K_MAC_seqnum, STR_8(seqnum) | type_seqnum |
    version_seqnum | length_seqnum | fragment_seqnum),
    
    where type_seqnum, version_seqnum, length_seqnum, and 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 RFC 5246) 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 and 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 RFC 5246). Since these ciphers are functioning as stream ciphers, the authenticate-then-encrypt method is secure, and as specified by [RFC 7366], 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 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; and

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, and 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 mode based on Cipher Block Chaining MAC (CBC-MAC) (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 and 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 RFC 5246) 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, and mac_length is equal to 4.
Note that the CNT_IMIT cipher suite uses the authenticate-then-encrypt method (see Appendix F.4 of RFC 5246). Since this cipher is functioning as a stream cipher, the authenticate-then-encrypt method is secure, and as specified by [RFC 7366], 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 preliminary secret.
 
    Client                                               Server

    ClientHello                  -------->
                                                    ServerHello
                                                    Certificate
                                             CertificateRequest*
                                 <--------      ServerHelloDone
    Certificate*
    ClientKeyExchange
    CertificateVerify*
    [ChangeCipherSpec]
    Finished                     -------->
                                             [ChangeCipherSpec]
                                 <--------             Finished
    Application Data             <------->     Application Data 
      
Notes for Figure 1:
  1. "*" indicates optional messages that are sent for the client authentication.
  2. 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 the client to exchange the preliminary secret).
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 preliminary 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 the 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 preliminary 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 Sections [4.2.4.1] and [4.2.4.2]) for the particular key export algorithm (see Sections [8.2.1] and [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 Sections [4.2.4.1] and [4.2.4.2]) for the particular key import algorithm (see Sections [8.2.1] and [8.2.2]) to extract the preliminary 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 RFC 5246 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 [RFC 5246]). 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 RFC 5246 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 [RFC 7366]).

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 RFC 5246.
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 RFC 5246.
If the CTR_OMAC or CNT_IMIT cipher suite is negotiated, the CertificateRequest message MUST meet the following requirements:
  • the CertificateRequest.supported_signature_algorithm field MUST contain only signature/hash algorithm pairs with the values {8, 64} or {8, 65} defined in Section 5;
  • the CertificateRequest.certificate_types field MUST contain only the gost_sign256 (67) or gost_sign512 (68) values defined in Section 7.

4.2.4.  ClientKeyExchange

The ClientKeyExchange message is defined as follows:
enum { vko_kdf_gost, vko_gost } KeyExchangeAlgorithm;

struct {
    select (KeyExchangeAlgorithm) {
        case vko_kdf_gost: GostKeyTransport;
        case vko_gost: TLSGostKeyTransportBlob;
    } exchange_keys;
} ClientKeyExchange;
The body of the ClientKeyExchange message consists of a GostKeyTransport/TLSGostKeyTransportBlob structure that contains an export representation of the preliminary secret PS.
The GostKeyTransport structure corresponds to the CTR_OMAC cipher suites and is described in Section 4.2.4.1, and the TLSGostKeyTransportBlob structure corresponds to the CNT_IMIT cipher suite and is described in Section 4.2.4.2.
The DER encoding rules are used to encode the GostKeyTransport and the TLSGostKeyTransportBlob structures.
4.2.4.1.  CTR_OMAC
In the CTR_OMAC cipher suites, the body of the ClientKeyExchange message consists of the GostKeyTransport structure that is defined below.
The client generates the ClientKeyExchange message in accordance with the following steps:
  1. Generates the ephemeral key pair (Q_eph, d_eph), where:
    d_eph is chosen from {1, ... , q_s - 1} at random;
    
    Q_eph = d_eph * P_s.
    
  2. Generates the preliminary secret PS, where PS is chosen from B_32 at random.
  3. Generates export keys (K_EXP_MAC and K_EXP_ENC) using the KEG algorithm defined in Section 8.3.1:
    H = HASH(r_c | r_s);
    
    K_EXP_MAC | K_EXP_ENC = KEG(d_eph, Q_s, H).
    
  4. Generates an export representation PSExp of the preliminary secret PS using the KExp15 algorithm defined in Section 8.2.1:
    IV = H[25..24 + n / 2];
    
    PSExp = KExp15(PS, K_EXP_MAC, K_EXP_ENC, IV).
    
  5. Generates the ClientKeyExchange message using the GostKeyTransport structure that is defined as follows:
    GostKeyTransport ::= SEQUENCE {
        keyExp               OCTET STRING,
        ephemeralPublicKey   SubjectPublicKeyInfo,
        ukm                  OCTET STRING OPTIONAL
    }
    
    SubjectPublicKeyInfo ::= SEQUENCE {
        algorithm            AlgorithmIdentifier,
        subjectPublicKey     BIT STRING
    }
    AlgorithmIdentifier ::= SEQUENCE {
        algorithm            OBJECT IDENTIFIER,
        parameters           ANY OPTIONAL
    }
    
    where the keyExp field contains the PSExp value, the ephemeralPublicKey field contains the Q_eph value, and the ukm field MUST be ignored by the server.
Upon receiving the ClientKeyExchange message, the server process is as follows.
  1. The following three conditions are checked. If any of these checks fail, then the server MUST abort the handshake with an alert.
    • Q_eph belongs to the same curve as server public key Q_s;
    • Q_eph is not equal to zero point;
    • q_s * Q_eph is equal to zero point.
  2. The export keys (K_EXP_MAC and K_EXP_ENC) are generated using the KEG algorithm defined in Section 8.3.1:
    H = HASH(r_c | r_s);
    
    K_EXP_MAC | K_EXP_ENC = KEG(d_s, Q_eph, H).
    
  3. The preliminary secret PS is extracted from the export representation PSExp using the KImp15 algorithm defined in Section 8.2.1:
    IV = H[25..24 + n / 2];
    
    PS = KImp15(PSExp, K_EXP_MAC, K_EXP_ENC, IV).
    
4.2.4.2.  CNT_IMIT
In the CNT_IMIT cipher suite, the body of the ClientKeyExchange message consists of a TLSGostKeyTransportBlob structure that is defined below.
The client generates the ClientKeyExchange message in accordance with the following steps:
  1. The ephemeral key pair (Q_eph, d_eph) is generated, where:
    d_eph is chosen from {1, ... , q_s - 1} at random;
    
    Q_eph = d_eph * P_s.
    
  2. The preliminary secret PS is generated, where PS is chosen from B_32 at random.
  3. The export key (K_EXP) is generated using the KEG_28147 algorithm defined in Section 8.3.2:
    H = HASH(r_c | r_s);
    
    K_EXP = KEG_28147(d_eph, Q_s, H).
    
  4. An export representation PSExp of the preliminary secret PS using the KExp28147 algorithm defined in Section 8.2.2 is generated:
    PSExp = IV | CEK_ENC | CEK_MAC = KExp28147(PS, K_EXP, H[1..8]).
    
  5. The ClientKeyExchange message is generated using the TLSGostKeyTransportBlob structure that is defined as follows:
    TLSGostKeyTransportBlob ::= SEQUENCE {
        keyBlob              GostR3410-KeyTransport
    }
    GostR3410-KeyTransport ::= SEQUENCE {
        sessionEncryptedKey  Gost28147-89-EncryptedKey,
        transportParameters  [0] IMPLICIT GostR3410-
                             TransportParameters OPTIONAL
    }
    Gost28147-89-EncryptedKey ::= SEQUENCE {
        encryptedKey         Gost28147-89-Key,
        maskKey              [0] IMPLICIT Gost28147-89-Key OPTIONAL,
        macKey               Gost28147-89-MAC
    }
    GostR3410-TransportParameters ::= SEQUENCE {

        ukm                  OCTET STRING
    }
    
    where GostR3410-KeyTransport, Gost28147-89-EncryptedKey, and GostR3410-TransportParameters are defined according to Section 4.2.1 of RFC 4490.
In the context of this document, the GostR3410-KeyTransport.transportParameters field is always used, the Gost28147-89-EncryptedKey.maskKey field is omitted, and the GostR3410-KeyTransport.transportParameters.ephemeralPublicKey field is always used.
The Gost28147-89-EncryptedKey.encryptedKey field contains the CEK_ENC value, the Gost28147-89-EncryptedKey.macKey field contains the CEK_MAC value, and the GostR3410-TransportParameters.ukm field contains the initialization vector (IV) value.
The keyBlob.transportParameters.ephemeralPublicKey field contains the client ephemeral public key Q_eph. The encryptionParamSet contains the value 1.2.643.7.1.2.5.1.1, which corresponds to the id-tc26-gost-28147-param-Z parameters set defined in [RFC 7836].
Upon receiving the ClientKeyExchange message, the server process is as follows.
  1. The following three conditions are checked. If either of these checks fails, then the server MUST abort the handshake with an alert.
    • Q_eph belongs to the same curve as server public key Q_s;
    • Q_eph is not equal to zero point;
    • q_s * Q_eph is equal to zero point.
  2. The export key (K_EXP) is generated using the KEG_28147 algorithm defined in Section 8.3.2:
    H = HASH(r_c | r_s);
    
    K_EXP = KEG_28147(d_s, Q_eph, H).
    
  3. The preliminary secret PS is extracted from the export representation PSExp using the KImp28147 algorithm defined in Section 8.2.2:
    PS = KImp28147(PSExp, K_EXP, H[1..8]).
    

4.2.5.  CertificateVerify

The client generates the value sgn as follows:
sgn = SIGN_{d_c}(handshake_messages) = str_l(r) | str_l(s)
where SIGN_{d_c} is the GOST R 34.10-2012 [RFC 7091] signature algorithm, d_c is a client long-term private key that corresponds to the client long-term public key Q_c from the client's certificate, l = 32 for the gostr34102012_256 value of the SignatureAndHashAlgorithm field, and l = 64 for the gostr34102012_512 value of the SignatureAndHashAlgorithm field.
Here, "handshake_messages" refers to all handshake messages sent or received, starting at ClientHello and up to CertificateVerify without the last message; it includes the type and length fields of the handshake messages.
The TLS CertificateVerify message is specified as follows:
struct {
    SignatureAndHashAlgorithm algorithm;
    opaque signature<0..2^16-1>;
} CertificateVerify;
where the SignatureAndHashAlgorithm structure is specified in Section 5, and the CertificateVerify.signature field contains the sgn value.

4.2.6.  Finished

The TLS Finished message is generated in accordance with Section 7.4.9 of RFC 5246.
The verify_data_length value is equal to 32 for the CTR_OMAC cipher suites and is equal to 12 for the CNT_IMIT cipher suite. The pseudorandom function (PRF) is defined in Section 4.3.4.

4.3.  Cryptographic Algorithms

4.3.1.  Block Cipher

The cipher suite TLS_GOSTR341112_256_WITH_KUZNYECHIK_CTR_OMAC MUST use Kuznyechik [RFC 7801] as a base block cipher for the encryption and MAC algorithm. The block length n is 16 bytes, and the key length k is 32 bytes.
The cipher suite TLS_GOSTR341112_256_WITH_MAGMA_CTR_OMAC MUST use Magma [RFC 8891] as a base block cipher for the encryption and MAC algorithm. The block length n is 8 bytes, and the key length k is 32 bytes.
The cipher suite TLS_GOSTR341112_256_WITH_28147_CNT_IMIT MUST use GOST 28147-89 as a base block cipher [RFC 5830] with the set of parameters id-tc26-gost-28147-param-Z defined in [RFC 7836]. The block length n is 8 bytes, and the key length k is 32 bytes.

4.3.2.  MAC Algorithm

The CTR_OMAC cipher suites use the One-Key MAC (OMAC) construction defined in [GOST3413-2015], which is the same as the Cipher-Based MAC (CMAC) mode defined in [CMAC] where the Kuznyechik or Magma block cipher (see Section 4.3.1) is used instead of the AES block cipher (see [IK2003] for more detail) as the MAC function. The resulting MAC length is equal to the block length, and the MAC key length is 32 bytes.
The CNT_IMIT cipher suite uses the MAC function gostIMIT28147 defined in Section 8.4 with the initialization vector IV = IV0, where IV0 in B_8 is a string of all zeros, with the CryptoPro Key Meshing algorithm defined in [RFC 4357]. The resulting MAC length is 4 bytes, and the MAC key length is 32 bytes.

4.3.3.  Encryption Algorithm

The CTR_OMAC cipher suites use the block cipher in the CTR-ACPKM encryption mode defined in [RFC 8645] as the ENC function. The section size N is 4 KB for the TLS_GOSTR341112_256_WITH_KUZNYECHIK_CTR_OMAC cipher suite and 1 KB for the TLS_GOSTR341112_256_WITH_MAGMA_CTR_OMAC cipher suite.
The CNT_IMIT cipher suite uses the block cipher in counter encryption mode (CNT) defined in Section 6 of RFC 5830, with the CryptoPro key meshing algorithm defined in [RFC 4357] 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 PRF for all the cipher suites defined in this document is the PRF_TLS_GOSTR3411_2012_256 function defined in [RFC 7836].
The hash function HASH for all the cipher suites defined in this document is the GOST R 34.11-2012 [RFC 6986] hash algorithm with a 32-byte (256-bit) hash code.

4.3.5.  SNMAX Parameter

The SNMAX parameter defines the maximal value of the seqnum sequence number during one TLS 1.2 connection and is defined as follows:
Cipher Suites SNMAX
  • TLS_GOSTR341112_256_WITH_KUZNYECHIK_CTR_OMAC
  • TLS_GOSTR341112_256_WITH_28147_CNT_IMIT
SNMAX = 264 - 1
TLS_GOSTR341112_256_WITH_MAGMA_CTR_OMAC SNMAX = 232 - 1

5.  New Values for the TLS 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 RFC 5246).
This document defines new values for the "TLS 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 [RFC 7091] signature algorithm with a 32-byte (256-bit) and 64-byte (512-bit) key length, respectively.
According to [RFC 7091], the GOST R 34.10-2012 signature algorithm with a 32-byte (256-bit) or 64-byte (512-bit) key length uses the GOST R 34.11-2012 [RFC 6986] hash algorithm with a 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 [RFC 8422]).
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 TLS Supported Groups Registry

The Supported Groups Extension indicates the set of elliptic curves supported by the client and is defined in [RFC 8422] and [RFC 7919].
This document defines new values for the "TLS Supported Groups" registry:
enum {
    GC256A(34), GC256B(35), GC256C(36), GC256D(37),
    GC512A(38), GC512B(39), GC512C(40),
} NamedGroup;
where the values correspond to the following curves:
Description Curve Identifier Value Reference
GC256A id-tc26-gost-3410-2012-256-paramSetA [RFC 7836]
GC256B id-GostR3410-2001-CryptoPro-A-ParamSet [RFC 4357]
GC256C id-GostR3410-2001-CryptoPro-B-ParamSet [RFC 4357]
GC256D id-GostR3410-2001-CryptoPro-C-ParamSet [RFC 4357]
GC512A id-tc26-gost-3410-12-512-paramSetA [RFC 7836]
GC512B id-tc26-gost-3410-12-512-paramSetB [RFC 7836]
GC512C id-tc26-gost-3410-2012-512-paramSetC [RFC 7836]
Table 2
Top   ToC   RFCv3-9189

7.  New Values for the TLS ClientCertificateType Identifiers Registry

The ClientCertificateType field of the CertificateRequest message contains a list of certificate types that the client may offer and is defined in Section 7.4.4 of RFC 5246.
This document defines new values for the "TLS 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 message as described in Section 4.2.5.

8.  Additional Algorithms

The cipher suites specified in this document rely on some additional algorithms, specified below; the use of these algorithms is not confined to the use in TLS specified in this document.

8.1.  TLSTREE

The TLSTREE function is defined as follows:
TLSTREE(K_root, i) = KDF_3(KDF_2(KDF_1(K_root, STR_8(i & C_1)),
STR_8(i & C_2)), STR_8(i & C_3)),
where
  • K_root in B_32;
  • i in {0, 1, ... , 264 - 1};
  • C_1, C_2, C_3 are constants defined by the particular cipher suite (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 [RFC 7836]:
    KDF_1(K, D) = KDF_GOSTR3411_2012_256(K, "level1", D);
    
    KDF_2(K, D) = KDF_GOSTR3411_2012_256(K, "level2", D); and
    
    KDF_3(K, D) = KDF_GOSTR3411_2012_256(K, "level3", D).
    

8.1.1.  Key Tree Parameters

TLS_GOSTR341112_256_WITH_KUZNYECHIK_CTR_OMAC
  • C_1=0xFFFFFFFF00000000
  • C_2=0xFFFFFFFFFFF80000
  • C_3=0xFFFFFFFFFFFFFFC0

8.2.  Key Export and Key Import Algorithms

8.2.1.  KExp15 and KImp15 Algorithms

Algorithms KExp15 and KImp15 use the block cipher determined by the particular cipher suite.
The KExp15 key export algorithm is defined as follows:
+------------------------------------------------------------+

|------------------------------------------------------------|
|  Input:                                                    |
|  - secret S to be exported, S in B*,                       |
|  - key K_Exp_MAC in B_k,                                   |
|  - key K_Exp_ENC in B_k,                                   |
|  - IV in B_{n/2}                                           |
|  Output:                                                   |
|  - export representation SExp in B_{L(S)+n}                |
|------------------------------------------------------------|
|  1. CEK_MAC = OMAC(K_Exp_MAC, IV | S), CEK_MAC in B_n      |
|  2. SExp = CTR-Encrypt(K_Exp_ENC, IV, S | CEK_MAC)         |
|  3. return SExp                                            |
+------------------------------------------------------------+
where the OMAC function is defined in [MODES] and the CTR-Encrypt(K, IV, S) function denotes the encryption of message S on key K and nonce IV in the CTR mode with s = n (see [MODES]).
The KImp15 key import algorithm is defined as follows:
+-------------------------------------------------------------------+
|   KImp15(SExp, K_Exp_MAC, K_Exp_ENC, IV)                          |
|-------------------------------------------------------------------|
|  Input:                                                           |
|  - export representation SExp in B*                               |
|  - key K_Exp_MAC in B_k,                                          |
|  - key K_Exp_ENC in B_k,                                          |
|  - IV in B_{n/2}                                                  |
|  Output:                                                          |
|  - secret S in B_{L(SExp)-n} or FAIL                              |
|-------------------------------------------------------------------|
|  1. S | CEK_MAC = CTR-Decrypt(K_Exp_ENC, IV, SExp), CEK_MAC in B_n|
|  2. If CEK_MAC = OMAC(K_Exp_MAC, IV | S)                          |
|        then return S; else return FAIL                            |
+-------------------------------------------------------------------+
where the OMAC function is defined in [MODES] and the CTR-Decrypt(K, IV, S) function denotes the decryption of message S on key K and nonce IV in the CTR mode (see [MODES]).
The keys K_Exp_MAC and K_Exp_ENC MUST be independent. For every pair of keys (K_Exp_ENC, K_Exp_MAC), the IV values MUST be unique. For the import of a key with the KImp15 algorithm, the IV value may be sent with the export key representation.

8.2.2.  KExp28147 and KImp28147 Algorithms

The KExp28147 key export algorithm is defined as follows:

|  Output:                                                       |

|             CEK_MAC = SExp[41..44]                             |
|  2. if IV' != IV then return FAIL; else                        |

|  4. If CEK_MAC = gost28147IMIT(IV, K, S)                       |
|        then return S; else return FAIL                         |

8.3.2.  KEG_28147 Algorithm

The KEG_28147 algorithm is defined as follows:
+----------------------------------------------------------------+
|  KEG_28147(d, Q, H)                                            |
|----------------------------------------------------------------|
|  Input:                                                        |

|  - H in B_32.                                                  |
|  Output:                                                       |

|  4. return K = CPDivers(UKM, R)                                |
+----------------------------------------------------------------+
where the VKO_256 function is equal to the VKO_GOSTR3410_2012_256 function defined in [RFC 7836] and the CPDivers function corresponds to the CryptoPro KEK Diversification Algorithm defined in [RFC 4357], which takes as input the User Keying Material (UKM) value and the key value.

8.4.  gostIMIT28147

gost28147IMIT(IV, K, M) is a MAC algorithm with a 4-byte 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, m is the smallest, non-negative solution to the equation (L(M) + m) mod 8 = 0, and the MAC28147 function corresponds to the MAC generation mode defined in [RFC 5830] with a 4-byte length output.

9.  IANA Considerations

IANA has added the following values to the "TLS Cipher Suites" registry:
Value Description DTLS-OK Recommended Reference
0xC1,0x00 TLS_GOSTR341112_256_-WITH_KUZNYECHIK_CTR_OMAC N N RFC 9189
0xC1,0x01 TLS_GOSTR341112_256_-WITH_MAGMA_CTR_OMAC N N RFC 9189
0xC1,0x02 TLS_GOSTR341112_256_-WITH_28147_CNT_IMIT N N RFC 9189
Table 4
IANA has added the following values to the "TLS SignatureAlgorithm" registry:
Value Description DTLS-OK Reference
64 gostr34102012_256 Y RFC 9189
65 gostr34102012_512 Y RFC 9189
Table 5
IANA has added the following values to the "TLS SignatureScheme" registry:
Value Description Recommended Reference
0x0840 Reserved for backward compatibility N RFC 9189
0x0841 Reserved for backward compatibility N RFC 9189
Table 6
IANA has also added the following footnote to values 64 and 65 in the "TLS SignatureAlgorithm" registry:

These values were 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 the following values to the "TLS Supported Groups" registry:
Value Description DTLS-OK Recommended Reference
34 GC256A Y N RFC 9189
35 GC256B Y N RFC 9189
36 GC256C Y N RFC 9189

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; the 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); the 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 [RFC 4357] and [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
The client should be prepared to handle any of these correctly if the corresponding group is included in the supported_groups extension (see [RFC 8422] and [RFC 7919]).

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 a guess is approximately equal to 2-32, which is acceptable in some practical cases.
