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] (note that [RFC5246] has been obsoleted by [RFC8446] ) 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], the signature algorithm GOST R 34.10-2012 [RFC7091], 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 [RFC7801] and [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 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. 2. Conventions Used in This Document The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here. 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}. B* the set of all byte strings of a finite length (hereinafter referred to as "strings"), including the empty string. A[i..j] the string A[i..j] = (a_i, a_{i+1}, ... , a_j) in B_{j-i+1}, where A = (a_1, ... , a_t) in B_t and 1<=i<=j<=t. L(A) the length of the byte string A in bytes. A | C concatenation of strings A and C both belonging to B*, i.e., a string in B_{L(A)+L(C)}, where the left substring in B_L(A) is equal to A and the right substring in B_L(C) is equal to C. 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 = 256^(t-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 = 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 * a_2 + a_1 (the interpretation of the byte string in little-endian format as an integer). k the length of the block cipher key in bytes. n the length of the block cipher block in bytes. Q_c the public key stored in the client's certificate. d_c the private key that corresponds to the Q_c key. Q_s the public key stored in the server's certificate. d_s the private key that corresponds to the Q_s key. q_s an order of a cyclic subgroup of the elliptic curve points group containing point Q_s. P_s the distinguished generator of the subgroup of order q_s that belongs to the same curve as Q_s. r_c the random string contained in the ClientHello.random field (see [RFC5246]). r_s the random string contained in the 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 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 [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 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 [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 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 [RFC5246], 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 [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 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 [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 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 [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, 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 [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 preliminary secret. Client Server ClientHello --------> ServerHello Certificate CertificateRequest* <-------- ServerHelloDone Certificate* ClientKeyExchange CertificateVerify* [ChangeCipherSpec] Finished --------> [ChangeCipherSpec] <-------- Finished Application Data <-------> Application Data Figure 1: Message Flow for a Full Handshake 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 [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]). 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 [RFC5246]. 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 { encryptionParamSet OBJECT IDENTIFIER, ephemeralPublicKey [0] IMPLICIT SubjectPublicKeyInfo OPTIONAL, ukm OCTET STRING } where GostR3410-KeyTransport, Gost28147-89-EncryptedKey, and GostR3410-TransportParameters are defined according to Section 4.2.1 of [RFC4490]. 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 [RFC7836]. 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 [RFC7091] 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 [RFC5246]. 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 [RFC7801] 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 [RFC8891] 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 [RFC5830] with the set of parameters id-tc26-gost-28147-param-Z defined in [RFC7836]. 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 [RFC4357]. 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 [RFC8645] 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 [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 PRF for all the cipher suites defined in this document is the PRF_TLS_GOSTR3411_2012_256 function defined in [RFC7836]. The hash function HASH for all the cipher suites defined in this document is the GOST R 34.11-2012 [RFC6986] 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 | SNMAX = | | TLS_GOSTR341112_256_WITH_28147_CNT_IMIT | 2^64 - 1 | +-------------------------------------------------+----------+ | TLS_GOSTR341112_256_WITH_MAGMA_CTR_OMAC | SNMAX = | | | 2^32 - 1 | +-------------------------------------------------+----------+ Table 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 [RFC5246]). 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 [RFC7091] signature algorithm with a 32-byte (256-bit) and 64-byte (512-bit) key length, respectively. According to [RFC7091], 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 [RFC6986] 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 [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 TLS Supported Groups Registry The Supported Groups Extension indicates the set of elliptic curves supported by the client and is defined in [RFC8422] and [RFC7919]. 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 | [RFC7836] | +-------------+----------------------------------------+-----------+ | GC256B | id-GostR3410-2001-CryptoPro-A-ParamSet | [RFC4357] | +-------------+----------------------------------------+-----------+ | GC256C | id-GostR3410-2001-CryptoPro-B-ParamSet | [RFC4357] | +-------------+----------------------------------------+-----------+ | GC256D | id-GostR3410-2001-CryptoPro-C-ParamSet | [RFC4357] | +-------------+----------------------------------------+-----------+ | GC512A | id-tc26-gost-3410-12-512-paramSetA | [RFC7836] | +-------------+----------------------------------------+-----------+ | GC512B | id-tc26-gost-3410-12-512-paramSetB | [RFC7836] | +-------------+----------------------------------------+-----------+ | GC512C | id-tc26-gost-3410-2012-512-paramSetC | [RFC7836] | +-------------+----------------------------------------+-----------+ Table 2 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 [RFC5246]. 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, ... , 2^64 - 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 [RFC7836]: 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 The CTR_OMAC cipher suites use the TLSTREE function for the rekeying approach. The constants for it are defined as in the table below. +============================================+======================+ |Cipher Suites |C_1, C_2, C_3 | +============================================+======================+ |TLS_GOSTR341112_256_WITH_KUZNYECHIK_CTR_OMAC|C_1=0xFFFFFFFF00000000| | |C_2=0xFFFFFFFFFFF80000| | |C_3=0xFFFFFFFFFFFFFFC0| +--------------------------------------------+----------------------+ |TLS_GOSTR341112_256_WITH_MAGMA_CTR_OMAC |C_1=0xFFFFFFC000000000| | |C_2=0xFFFFFFFFFE000000| | |C_3=0xFFFFFFFFFFFFF000| +--------------------------------------------+----------------------+ Table 3 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: +------------------------------------------------------------+ | KExp15(S, K_Exp_MAC, K_Exp_ENC, IV) | |------------------------------------------------------------| | 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: +----------------------------------------------------------------+ | KExp28147(S, K, IV) | |----------------------------------------------------------------| | Input: | | - secret S to be exported, S in B_32, | | - key K in B_32, | | - IV in B_8. | | Output: | | - export representation SExp in B_44 | |----------------------------------------------------------------| | 1. CEK_MAC = gost28147IMIT(IV, K, S), CEK_MAC in B_4 | | 2. CEK_ENC = ECB-Encrypt(K, S), CEK_ENC in B_32 | | 3. return SExp = IV | CEK_ENC | CEK_MAC | +----------------------------------------------------------------+ where the gost28147IMIT function is defined in Section 8.4 and the ECB-Encrypt(K, S) function denotes the encryption of message S on key K with the block cipher GOST 28147-89 in the electronic codebook (ECB) mode (see [RFC5830]). The KImp28147 key import algorithm is defined as follows: +----------------------------------------------------------------+ | KImp28147(SExp, K, IV) | |----------------------------------------------------------------| | Input: | | - export representation SExp in B_44, | | - key K in B_32, | | - IV in B_8. | | Output: | | - imported secret S in B_32 or FAIL | |----------------------------------------------------------------| | 1. extract from SExp | | IV' = SExp[1..8], | | CEK_ENC = SExp[9..40], | | CEK_MAC = SExp[41..44] | | 2. if IV' != IV then return FAIL; else | | 3. S = ECB-Decrypt(K, CEK_ENC), S in B_32 | | 4. If CEK_MAC = gost28147IMIT(IV, K, S) | | then return S; else return FAIL | +----------------------------------------------------------------+ where the gost28147IMIT function is defined in Section 8.4 and the ECB-Decrypt(CEK_ENC, M) function denotes the decryption of ciphertext CEK_ENC on key K with a block cipher GOST 28147-89 in the ECB mode (see [RFC5830]). 8.3. Key Exchange Generation Algorithms 8.3.1. KEG Algorithm The KEG algorithm is defined as follows: +----------------------------------------------------------------+ | KEG(d, Q, H) | |----------------------------------------------------------------| | Input: | | - private key d, | | - public key Q, | | - H in B_32. | | Output: | | - key material K in B_64. | |----------------------------------------------------------------| | 1. If q * Q is not equal to zero point | | return FAIL | | 2. If 2^254 < q < 2^256 | | return KEG_256(d, Q, H) | | 3. If 2^508 < q < 2^512 | | return KEG_512(d, Q, H) | | 4. return FAIL | +----------------------------------------------------------------+ where q is an order of a cyclic subgroup of elliptic curve points group containing point Q, d in {1, ... , q - 1}. The KEG_256 algorithm is defined as follows: +----------------------------------------------------------------+ | KEG_256(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. K_EXP = VKO_256(d, Q, UKM) | | 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: +----------------------------------------------------------------+ | 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] and the CPDivers function corresponds to the CryptoPro KEK Diversification Algorithm defined in [RFC4357], 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'' = (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 [RFC5830] 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_ |N |N |RFC 9189 | | | WITH_KUZNYECHIK_CTR_OMAC | | | | +---------+--------------------------+-------+------------+---------+ |0xC1,0x01| TLS_GOSTR341112_256_ |N |N |RFC 9189 | | | WITH_MAGMA_CTR_OMAC | | | | +---------+--------------------------+-------+------------+---------+ |0xC1,0x02| TLS_GOSTR341112_256_ |N |N |RFC 9189 | | | WITH_28147_CNT_IMIT | | | | +---------+--------------------------+-------+------------+---------+ 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 | N | RFC 9189 | | | compatibility | | | +--------+-----------------------+-------------+-----------+ | 0x0841 | Reserved for backward | N | RFC 9189 | | | compatibility | | | +--------+-----------------------+-------------+-----------+ 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.

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 [RFC4357] 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 [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 a guess is approximately equal to 2^-32, which is acceptable in some practical cases. 12. References 12.1.
