Introduction This document specifies three new cipher suites for the Transport Layer Security (TLS) Protocol Version 1.2 [RFC5246] to support the set of Russian cryptographic standard algorithms (called GOST algorithms). These cipher suites use the same hash algorithm GOST R 34.11-2012 [GOST3411-2012] (the English version can be found in [RFC6986]) and the same signature algorithm GOST R 34.10-2012 [GOST3410-2012] (the English version can be found in [RFC7091]) but use different encryption and MAC algorithms, so they are divided into two types: the CTR_OMAC cipher suites and the CNT_IMIT cipher suite. The CTR_OMAC cipher suites use the GOST R 34.12-2015 [GOST3412-2015] block ciphers (the English version can be found in [RFC7801]) and have the following values: TLS_GOSTR341112_256_WITH_KUZNYECHIK_CTR_OMAC = {TBD1}; TLS_GOSTR341112_256_WITH_MAGMA_CTR_OMAC = {TBD2}. The CNT_IMIT cipher suite uses the GOST 28147-89 [GOST28147-89] block cipher (the English version can be found in [RFC5830]) and has the following value: TLS_GOSTR341112_256_WITH_28147_CNT_IMIT = {TBD3}.

Conventions Used in This Document The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119]. 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 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; |A| the byte length of the byte string A; A | C concatenation of strings A and C both belonging to B*, i.e., a string in B_{|A|+|C|}, where the left substring in B_|A| is equal to A, and the right substring in B_|C| is equal to C; A XOR C bitwise exclusive-or of strings A and C both belonging to B_t, 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 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 * Smyshlyaev, et al. Expires July 2, 2019 [Page 4] Internet-Draft GOST Cipher Suites for TLS 1.2 December 2018 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 byte-length of the block cipher key; n the byte-length of the block cipher block; 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 subgroup order of group of points of the elliptic curve that corresponds to Q_s; P_s the point of order q_s that belongs to the same curve as Q_s; r_c the random string contained in ClientHello.random field (see [RFC5246]); r_s the random string contained in ServerHello.random field (see [RFC5246]). 4. Cipher Suite Definitions 4.1. Record Payload Protection All of the cipher suites described in this document MUST use the "null" compression method (see Section 6.2.2 of [RFC5246] and Section 4.2.1). Note that the CompressionMethod.null operation is an identity operation; no fields are altered. All of the cipher suites described in this document use the stream cipher (see Section 4.3.3) to protect records. 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]): Smyshlyaev, et al. Expires July 2, 2019 [Page 5] Internet-Draft GOST Cipher Suites for TLS 1.2 December 2018 struct { ContentType type; ProtocolVersion version; uint16 length; GenericStreamCipher fragment; } TLSCiphertext; where TLSCiphertext.fragment is generated in accordance with Section 4.1.1 or Section 4.1.2. 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 in the 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 certain sequence number seqnum consists of: o K_ENC_seqnum in B_k; o K_MAC_seqnum in B_k; o 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 and the connection key material. IV_seqnum is calculated by adding seqnum value to sender_write_IV modulo 2^{(n/2)*8}: o K_ENC_seqnum = TLSTREE(sender_write_key, seqnum); Smyshlyaev, et al. Expires July 2, 2019 [Page 6] Internet-Draft GOST Cipher Suites for TLS 1.2 December 2018 o K_MAC_seqnum = TLSTREE(sender_write_MAC_key, seqnum); o IV_seqnum = STR_{n/2}((INT(sender_write_IV) + seqnum) mod 2^{(n/2)*8}). The TLSCiphertext.fragment that corresponds to the certain sequence number seqnum is equal to the ENCValue_seqnum value that is calculated as follows: 1. The MAC value (MACValue_seqnum) 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: MACData_seqnum = STR_8(seqnum) | type_seqnum | version_seqnum | length_seqnum | fragment_seqnum; MACValue_seqnum = MAC(K_MAC_seqnum, MACData_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): ENCData_seqnum = fragment_seqnum | MACValue_seqnum; ENCValue_seqnum = ENC(K_ENC_seqnum, IV_seqnum, ENCData_seqnum). 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: o sender_write_key in B_k; o sender_write_MAC_key in B_k; o sender_write_IV in B_n. The TLSCiphertext.fragment that corresponds to the certain sequence number seqnum is equal to the ENCValue_seqnum value that is calculated as follows: 1. The MAC value (MACValue_seqnum) is generated by the MAC algorithm (see Section 4.3.2) as follows: Smyshlyaev, et al. Expires July 2, 2019 [Page 7] Internet-Draft GOST Cipher Suites for TLS 1.2 December 2018 MACData_i = STR_8(i) | type_i | version_i | length_i | fragment_i, i in {0, ... , seqnum}; MACValue_seqnum = MAC(sender_write_MAC_key, MACData_0 | ... | MACData_seqnum), where type_i, version_i, length_i, fragment_i are the TLSCompressed.type, TLSCompressed.version, TLSCompressed.length and TLSCompressed.fragment values of the record with the i sequence number. Implementation note: Due to the use of the CBC-MAC based mode it is not necessarily to store all previous fragments MACData_0, ... , MACData{i-1} to generate the MACValue_i fragment for the i-th record. It's enough to know only the 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): ENCData_i = fragment_i | MACValue_i, i in {0, ... , seqnum}; ENCValue_0 | ... | ENCValue_seqnum = ENC(sender_write_key, sender_write_IV, ENCData_0 | ... | ENCData_seqnum), where |ENCValue_i| = |ENCData_i|, i in {0, ... , seqnum}. Implementation note: Due to the use of the stream cipher it is not necessarily to store all previous fragments ENCData_0, ... , ENCData{i-1} to generate the ENCValue_i fragment for the i-th record. It's enough to know only the intermediate internal state of the ENC stream cipher. 4.2. Key Exchange and Authentication All of the cipher suites described in this document use ECDHE based schema to share the TLS premaster secret. Smyshlyaev, et al. Expires July 2, 2019 [Page 8] Internet-Draft GOST Cipher Suites for TLS 1.2 December 2018 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. * Indicates optional messages that are sent for the client authentication. 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). 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. Smyshlyaev, et al. Expires July 2, 2019 [Page 9] Internet-Draft GOST Cipher Suites for TLS 1.2 December 2018 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. The proposed cipher suites specify the ClientHello, ServerHello, ServerCertificate, CertificateRequest, ClientKeyExchange, CertificateVerify and Finished handshake messages, that are described in further detail below. 4.2.1. Hello Messages The ClientHello message is generated in accordance with the following requirements: o The ClientHello.compression_methods field SHOULD contain exactly one byte, set to zero, which corresponds to the "null" compression method. o The ClientHello.extensions field SHOULD contain the signature_algorithms extension (see [RFC5246]) with the values defined in Section 5. If the negotiated cipher suite is one of CTR_OMAC/CTR_IMIT and the client implementation does not support generating the signature_algorithms extension with the appropriate values, 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, TBD4} and {8, TBD5}. o The ClientHello.extensions field is RECOMMENDED to contain the extended_master_secret (see [RFC7627]) and the renegotiation_info (see [RFC5746]) extensions. o The ClientHello.extensions field MAY contain the supported_groups extension (see [RFC8422] and [RFC7919]) with the values defined in Section 6. The ServerHello message is generated in accordance with the following requirements: o The ServerHello.compression_method field MUST contain exactly one byte, set to zero, which corresponds to the "null" compression method. Smyshlyaev, et al. Expires July 2, 2019 [Page 10] Internet-Draft GOST Cipher Suites for TLS 1.2 December 2018 o The ServerHello.extensions field is RECOMMENDED to contain the extended_master_secret (see [RFC7627]) and the renegotiation_info (see [RFC5746]) extensions. o The ServerHello.extensions field MUST NOT contain the encrypt_then_mac extension (see [RFC7366]). If the extended_master_secret extension is agreed, then the master secret value MUST be calculated in accordance with [RFC7627]. 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]. Note: If the client has used supported_groups extension, the public key in the server's certificate MUST respect the client's choice of elliptic curves. 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 when requesting client authentication and is specified in accordance with [RFC5246] as follows. struct { ClientCertificateType certificate_types<1..2^8-1>; SignatureAndHashAlgorithm supported_signature_algorithms<2..2^16-2>; DistinguishedName certificate_authorities<0..2^16-1>; } CertificateRequest; If the CTR_OMAC or CNT_IMIT cipher suite is negotiated, the CertificateRequest message MUST meet the following requirements: o the CertificateRequest.supported_signature_algorithm field MUST contain only signature/hash algorithm pairs with the values {8, TBD4} or {8, TBD5} defined in Section 5; Smyshlyaev, et al. Expires July 2, 2019 [Page 11] Internet-Draft GOST Cipher Suites for TLS 1.2 December 2018 o the CertificateRequest.certificate_types field MUST contain only the gost_sign256 (TBD13) or gost_sign512 (TBD14) 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 premaster secret PS. The GostKeyTransport structure corresponds to the CTR_OMAC cipher suites and is described in Section 4.2.4.1 and the TLSGostKeyTransportBlob corresponds to CNT_IMIT cipher suite and is described in Section 4.2.4.2. 4.2.4.1. CTR_OMAC In case of the CTR_OMAC cipher suites the body of the ClientKeyExchange message consists of the GostKeyTransport structure that is defined bellow. 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 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); Smyshlyaev, et al. Expires July 2, 2019 [Page 12] Internet-Draft GOST Cipher Suites for TLS 1.2 December 2018 K_EXP_MAC | K_EXP_ENC = KEG(d_eph, Q_s, H). 3. Generates an export representation PSExp of the premaster 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). 4. 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 BITSTRING } 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 it as follows. 1. Checks the following three conditions. If either of these checks fails, then the server MUST abort the handshake with an alert. o Q_eph belongs to the same curve as server public key Q_s; o Q_eph is not equal to zero point; o q_s * Q_eph is equal to zero point. 2. Generates export keys (K_EXP_MAC and K_EXP_ENC) using the KEG algorithm defined in Section 8.3.1: Smyshlyaev, et al. Expires July 2, 2019 [Page 13] Internet-Draft GOST Cipher Suites for TLS 1.2 December 2018 H = HASH(r_c | r_s); K_EXP_MAC | K_EXP_ENC = KEG(d_s, Q_eph, H). 3. Extracts the premaster secret PS 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 case of the CNT_IMIT cipher suite the body of the ClientKeyExchange message consists of a TLSGostKeyTransportBlob structure that is defined bellow. 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 export key (K_EXP) 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). 3.

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 uses Magma [GOST3412-2015] as a base block cipher for the encryption and MAC algorithm.

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 message authentication code 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. Smyshlyaev, et al. Expires July 2, 2019 [Page 17] Internet-Draft GOST Cipher Suites for TLS 1.2 December 2018 4.3.3.

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 [RFC7836].

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 TBD4 (gostr34102012_256) or TBD5 (gostr34102012_512) value, the SignatureAndHashAlgorithm.hash field of this pair MUST contain the "Intrinsic" value 8 (see [RFC8422]). 6.

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 offer and is defined in Section 7.4.4 of [RFC5246].

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. Smyshlyaev, et al.
