Introduction + + This document defines four new cipher suites (the TLS13_GOST cipher + suites) and seven new signature schemes (the TLS13_GOST signature + schemes) for the Transport Layer Security (TLS) Protocol Version 1.3 + that are based on Russian cryptographic standards GOST R 34.12-2015 + [RFC7801], GOST R 34.11-2012 [RFC6986], and GOST R 34.10-2012 + [RFC7091]. + + The TLS13_GOST cipher suites (see Section 4) have the following + values: + + TLS_GOSTR341112_256_WITH_KUZNYECHIK_MGM_L = {0xC1, 0x03} + + TLS_GOSTR341112_256_WITH_MAGMA_MGM_L = {0xC1, 0x04} + + TLS_GOSTR341112_256_WITH_KUZNYECHIK_MGM_S = {0xC1, 0x05} + + TLS_GOSTR341112_256_WITH_MAGMA_MGM_S = {0xC1, 0x06} + + Each TLS13_GOST cipher suite specifies a pair (record protection + algorithm, hash algorithm) such that: + + * The record protection algorithm is the Authenticated Encryption + with Associated Data (AEAD) algorithm (see Section 4.1.1) based on + the GOST R 34.12-2015 block cipher [RFC7801] in the Multilinear + Galois Mode (MGM) [RFC9058] and the external re-keying approach + (see [RFC8645]) intended for increasing the lifetime of symmetric + keys used to protect records. + + * The hash algorithm is the GOST R 34.11-2012 algorithm [RFC6986]. + + Note: The TLS13_GOST cipher suites are divided into two types: the + "_S" (strong) cipher suites and the "_L" (light) cipher suites + (depending on the key lifetime limitations, see Sections 4.1.2 and + 4.1.3). + + The TLS13_GOST signature schemes have the following values: + + gostr34102012_256a = 0x0709 + + gostr34102012_256b = 0x070A + + gostr34102012_256c = 0x070B + + gostr34102012_256d = 0x070C + + gostr34102012_512a = 0x070D + + gostr34102012_512b = 0x070E + + gostr34102012_512c = 0x070F + + Each TLS13_GOST signature scheme specifies a pair (signature + algorithm, elliptic curve) such that: + + * The signature algorithm is the GOST R 34.10-2012 algorithm + [RFC7091]. + + * The elliptic curve is one of the curves defined in Section 5.2. + + This document also specifies the key exchange mechanism with GOST + algorithms for the TLS 1.3 protocol (see Section 6.1). + + Additionally, this document specifies a TLS13_GOST profile of the TLS + 1.3 protocol with GOST algorithms so that implementers can produce + interoperable implementations. It uses TLS13_GOST cipher suites, + TLS13_GOST signature schemes, and key exchange mechanisms that are + defined in this document. + +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 "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 in 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_2, ... , a_t) in B_t and + 1<=i<=j<=t. + + A[i] The integer a_i in {0, ... , 255}, where A = (a_1, + a_2, ... , a_t) in B_t and 1<=i<=t. + + |A| The length of the byte string A in bytes. + + A | C The 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. + + 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). + + k The length of the block cipher key in bytes. + + n The length of the block cipher block in bytes. + + IVlen The length of the initialization vector in bytes. + + S The length of the authentication tag in bytes. + + E_i The elliptic curve indicated by the client in + "supported_groups" extension. + + O_i The zero point of the elliptic curve E_i. + + m_i The order of the group of points belonging to the + elliptic curve E_i. + + q_i The order of the cyclic subgroup of the group of + points belonging to the elliptic curve E_i. + + h_i The cofactor of the cyclic subgroup that is equal to + m_i / q_i. + + Q_sign The public key stored in the endpoint's certificate. + + d_sign The private key that corresponds to the Q_sign key. + + P_i The point of the elliptic curve E_i of the order q_i. + + (d_C^i, Q_C^i) The client's ephemeral key pair that consists of the + private key and the public key corresponding to the + elliptic curve E_i. + + (d_S^i, Q_S^i) The server's ephemeral key pair that consists of the + private key and the public key corresponding to the + elliptic curve E_i. + +4. Cipher Suite Definition + + This section defines the following four TLS13_GOST cipher suites: + + * CipherSuite TLS_GOSTR341112_256_WITH_KUZNYECHIK_MGM_L = {0xC1, + 0x03}; + + * CipherSuite TLS_GOSTR341112_256_WITH_MAGMA_MGM_L = {0xC1, 0x04}; + + * CipherSuite TLS_GOSTR341112_256_WITH_KUZNYECHIK_MGM_S = {0xC1, + 0x05}; + + * CipherSuite TLS_GOSTR341112_256_WITH_MAGMA_MGM_S = {0xC1, 0x06}. + + Each cipher suite specifies a pair consisting of a record protection + algorithm (see Section 4.1) and a hash algorithm (Section 4.2). + +4.1. Record Protection Algorithm + + In accordance with Section 5.2 of [RFC8446], the record protection + algorithm translates a TLSPlaintext structure into a TLSCiphertext + structure. If the TLS13_GOST cipher suite is negotiated, the + encrypted_record field of the TLSCiphertext structure MUST be set to + the AEADEncrypted value computed as follows: + + AEADEncrypted = AEAD-Encrypt(sender_record_write_key, nonce, + additional_data, plaintext), + + where + + * the AEAD-Encrypt function is defined in Section 4.1.1; + + * the sender_record_write_key is a key derived from sender_write_key + (see Section 7.3 of [RFC8446]) using the TLSTREE function defined + in Section 4.1.2 and sequence number seqnum as follows: + + sender_record_write_key = TLSTREE(sender_write_key, seqnum); + + * the nonce is a value derived from sequence number seqnum and + sender_write_iv (see Section 7.3 of [RFC8446]) in accordance with + Section 5.3 of [RFC8446]; + + * the additional_data value is a record header that is generated in + accordance with Section 5.2 of [RFC8446]; + + * the plaintext value is the TLSInnerPlaintext structure encoded in + accordance with Section 5.2 of [RFC8446]. + + Note 1: The AEAD-Encrypt function is exactly the same as the AEAD- + Encrypt function defined in [RFC8446], such that the key (the first + argument) is calculated from sender_write_key and sequence number + seqnum for each message separately to support the external re-keying + approach according to [RFC8645]. + + Note 2: Sequence number is a value in the range 0-SNMAX, where the + SNMAX value is defined in Section 4.1.3. The SNMAX parameter is + specified by a particular TLS13_GOST cipher suite to limit an amount + of data that can be encrypted under the same traffic key material + (sender_write_key, sender_write_iv). + + The record deprotection algorithm reverses the process of the record + protection. In order to decrypt and verify a protected record with + sequence number seqnum, the algorithm takes sender_record_write_key + as an input, which is derived from sender_write_key, nonce, + additional_data, and the AEADEncrypted value. The algorithm outputs + the res value that is either plaintext or an error indicating that + the decryption failed. If a TLS13_GOST cipher suite is negotiated, + the res value MUST be computed as follows: + + res = AEAD-Decrypt(sender_record_write_key, nonce, + additional_data, AEADEncrypted), + + where the AEAD-Decrypt function is as defined in Section 4.1.1. + + Note: The AEAD-Decrypt function is exactly the same as the AEAD- + Decrypt function defined in [RFC8446], such that the key (the first + argument) is calculated from sender_write_key and sequence number + seqnum for each message separately to support the external re-keying + approach according to [RFC8645]. + +4.1.1. AEAD Algorithm + + The AEAD-Encrypt and AEAD-Decrypt functions are defined as follows: + + +-------------------------------------------------------------------+ + | AEAD-Encrypt(K, nonce, A, P) | + |-------------------------------------------------------------------| + | Input: | + | - encryption key K in B_k, | + | - unique vector nonce in B_IVlen, | + | - additional authenticated data A in B_r, r >= 0, | + | - plaintext P in B_t, t >= 0. | + | Output: | + | - ciphertext C in B_{|P|}, | + | - authentication tag T in B_S. | + |-------------------------------------------------------------------| + | 1. MGMnonce = STR_1(nonce[1] & 0x7f) | nonce[2..IVlen]; | + | 2. (MGMnonce, A, C, T) = MGM-Encrypt(K, MGMnonce, A, P); | + | 3. Return C | T. | + +-------------------------------------------------------------------+ + + +-------------------------------------------------------------------+ + | AEAD-Decrypt(K, nonce, A, C | T) | + |-------------------------------------------------------------------| + | Input: | + | - encryption key K in B_k, | + | - unique vector nonce in B_IVlen, | + | - additional authenticated data A in B_r, r >= 0, | + | - ciphertext C in B_t, t >= 0, | + | - authentication tag T in B_S. | + | Output: | + | - plaintext P in B_{|C|} or FAIL. | + |-------------------------------------------------------------------| + | 1. MGMnonce = STR_1(nonce[1] & 0x7f) | nonce[2..IVlen]; | + | 2. res' = MGM-Decrypt(K, MGMnonce, A, C, T); | + | 3. IF res' = FAIL then return FAIL; | + | 4. IF res' = (A, P) then return P. | + +-------------------------------------------------------------------+ + + where + + * the MGM-Encrypt and MGM-Decrypt functions are defined in + [RFC9058]; + + * the length of authentication tag T is equal to n bytes (S = n); + + * the length of the nonce parameter is equal to n bytes (IVlen = n). + + Cipher suites TLS_GOSTR341112_256_WITH_KUZNYECHIK_MGM_L and + TLS_GOSTR341112_256_WITH_KUZNYECHIK_MGM_S MUST use Kuznyechik + [RFC7801] as a base block cipher for the AEAD algorithm. The block + length n is 16 bytes (n = 16) and the key length k is 32 bytes (k = + 32). + + Cipher suites TLS_GOSTR341112_256_WITH_MAGMA_MGM_L and + TLS_GOSTR341112_256_WITH_MAGMA_MGM_S MUST use Magma [RFC8891] as a + base block cipher for the AEAD algorithm. The block length n is 8 + bytes (n = 8) and the key length k is 32 bytes (k = 32). + +4.1.2. TLSTREE + + The TLS13_GOST cipher suites use the TLSTREE function to support the + external re-keying approach (see [RFC8645]). 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}; + + * KDF_j(K, D), j = 1, 2, 3, is the key derivation function defined + as follows: + + - KDF_1(K, D) = KDF_GOSTR3411_2012_256(K, "level1", D), + + - KDF_2(K, D) = KDF_GOSTR3411_2012_256(K, "level2", D), + + - KDF_3(K, D) = KDF_GOSTR3411_2012_256(K, "level3", D), + + where the KDF_GOSTR3411_2012_256 function is defined in [RFC7836], + K in B_32, D in B_8; + + * C_1, C_2, C_3 are the constants defined by each cipher suite as + follows: + + +===========================================+======================+ + | CipherSuites |C_1, C_2, C_3 | + +===========================================+======================+ + | TLS_GOSTR341112_256_WITH_KUZNYECHIK_MGM_L |C_1=0xf800000000000000| + | | | + | |C_2=0xfffffff000000000| + | | | + | |C_3=0xffffffffffffe000| + +-------------------------------------------+----------------------+ + | TLS_GOSTR341112_256_WITH_MAGMA_MGM_L |C_1=0xffe0000000000000| + | | | + | |C_2=0xffffffffc0000000| + | | | + | |C_3=0xffffffffffffff80| + +-------------------------------------------+----------------------+ + | TLS_GOSTR341112_256_WITH_KUZNYECHIK_MGM_S |C_1=0xffffffffe0000000| + | | | + | |C_2=0xffffffffffff0000| + | | | + | |C_3=0xfffffffffffffff8| + +-------------------------------------------+----------------------+ + | TLS_GOSTR341112_256_WITH_MAGMA_MGM_S |C_1=0xfffffffffc000000| + | | | + | |C_2=0xffffffffffffe000| + | | | + | |C_3=0xffffffffffffffff| + +-------------------------------------------+----------------------+ + + Table 1 + +4.1.3.

However, the TLS13_GOST profile MUST use modes based on the + Diffie-Hellman protocol over elliptic curves. + + In accordance with [RFC8446], PSKs can be divided into two types: + + * internal PSKs that can be established during the previous + connection; + + * external PSKs that can be established out of band. + + If the TLS13_GOST profile is used, PSK-only key exchange mode SHOULD + be established via the internal PSKs, and external PSKs SHOULD be + used only in PSK with ECDHE mode (see more in Section 9). + + If the TLS13_GOST profile is used and ECDHE or PSK with ECDHE key + exchange mode is used, the ECDHE shared secret SHOULD be calculated + in accordance with Section 6.1.1 on the basis of one of the elliptic + curves defined in Section 6.1.2. + +6.1.1. ECDHE Shared Secret Calculation + + If the TLS13_GOST profile is used, the ECDHE shared secret SHOULD be + calculated in accordance with Sections 6.1.1.1 and 6.1.1.2. The + public ephemeral keys used to obtain the ECDHE shared secret SHOULD + be represented in the format described in Section 6.1.1.3. + +6.1.1.1. ECDHE Shared Secret Calculation on the Client Side + + The client calculates the ECDHE shared secret in accordance with the + following steps: + + Step 1. The client chooses from all supported curves E_1, ..., E_R + the set of curves E_{i_1}, ..., E_{i_r}, 1 <= i_1 <= i_r <= + R, where + + * r >= 1 in the case of the first ClientHello message; + + * r = 1 in the case of responding to the HelloRetryRequest + message; E_{i_1} corresponds to the curve indicated in + the "key_share" extension in the HelloRetryRequest + message. + + Step 2. The client generates ephemeral key pairs (d_C^{i_1}, + Q_C^{i_1}), ..., (d_C^{i_r}, Q_C^{i_r}) corresponding to the + curves E_{i_1}, ..., E_{i_r}, where for each i in {i_1, ..., + i_r}: + + * d_C^i is chosen from {1, ..., q_i - 1} at random; + + * Q_C^i = d_C^i * P_i. + + Step 3. The client sends the ClientHello message specified in + accordance with Section 4.1.2 of [RFC8446] and Section 6.3.1 + that contains: + + * "key_share" extension with public ephemeral keys + Q_C^{i_1}, ..., Q_C^{i_r} built in accordance with + Section 4.2.8 of [RFC8446]; + + * "supported_groups" extension with supported curves E_1, + ..., E_R built in accordance with Section 4.2.7 of + [RFC8446]. + + Note: The client MAY send an empty "key_share" extension + in the first ClientHello message to request a group + selection from the server in the HelloRetryRequest + message and to generate an ephemeral key for the selected + group only. The ECDHE shared secret may be calculated + without sending HelloRetryRequest message if the + "key_share" extension in the first ClientHello message + contains the value corresponding to the curve that is + selected by the server. + + Step 4. If the HelloRetryRequest message is received, the client + MUST return to Step 1 and choose correct parameters in + accordance with Section 4.1.2 of [RFC8446]. If the + ServerHello message is received, the client proceeds to the + next step. In other cases, the client MUST terminate the + connection with the "unexpected_message" alert. + + Step 5. The client extracts curve E_res and ephemeral key Q_S^res, + res in {1, ..., R}, from the ServerHello message and checks + whether Q_S^res belongs to E_res. If this check fails, the + client MUST terminate the connection with + "handshake_failure" alert. + + Step 6. The client generates Q^ECDHE: + + Q^ECDHE = (X^ECDHE, Y^ECDHE) = (h_res * d_C^res) * + Q_S^res. + + Step 7. The client MUST check whether the calculated shared secret + Q^ECDHE is not equal to the zero point O_res. If this check + fails, the client MUST terminate the connection with + "handshake_failure" alert. + + Step 8. The ECDHE shared secret is the byte representation of the + coordinate X^ECDHE of the point Q^ECDHE in the little-endian + format: + + ECDHE = str_{coordinate_length}(X^ECDHE), + + where the coordinate_length value is defined by the + particular elliptic curve (see Section 6.1.2). + +6.1.1.2. ECDHE Shared Secret Calculation on Server Side + + Upon receiving the ClientHello message, the server calculates the + ECDHE shared secret in accordance with the following steps: + + Step 1. The server chooses the curve E_res, res in {1, ..., R}, from + the list of the curves E_1, ..., E_R indicated in the + "supported_groups" extension in the ClientHello message and + the corresponding public ephemeral key Q_C^res from the list + Q_C^{i_1}, ..., Q_C^{i_r}, 1 <= i_1 <= i_r <= R, indicated + in the "key_share" extension. If the corresponding public + ephemeral key is not found (res in {1, ..., R}\{i_1, ..., + i_r}), the server MUST send the HelloRetryRequest message + with the "key_share" extension indicating the selected + elliptic curve E_res and wait for the new ClientHello + message. + + Step 2. The server checks whether Q_C^res belongs to E_res. If this + check fails, the server MUST terminate the connection with + "handshake_failure" alert. + + Step 3. The server generates ephemeral key pair (d_S^res, Q_S^res) + corresponding to E_res: + + * d_S^res is chosen from {1, ..., q_res - 1} at random; + + * Q_S^res = d_S^res * P_res. + + Step 4. The server sends the ServerHello message generated in + accordance with Section 4.1.3 of [RFC8446] and Section 6.3.1 + with the "key_share" extension that contains public + ephemeral key Q_S^res corresponding to E_res. + + Step 5. The server generates Q^ECDHE: + + Q^ECDHE = (X^ECDHE, Y^ECDHE) = (h_res * d_S^res) * + Q_C^res. + + Step 6. The server MUST check whether the calculated shared secret + Q^ECDHE is not equal to the zero point O_res. If this check + fails, the server MUST abort the handshake with + "handshake_failure" alert. + + Step 7. The ECDHE shared secret is the byte representation of the + coordinate X^ECDHE of the point Q^ECDHE in the little-endian + format: + + ECDHE = str_{coordinate_length}(X^ECDHE), + + where the coordinate_length value is defined by the + particular elliptic curve (see Section 6.1.2). + +6.1.1.3. Public Ephemeral Key Representation + + This section defines the representation format of the public + ephemeral keys generated during the ECDHE shared secret calculation + (see Sections 6.1.1.1 and 6.1.1.2). + + If the TLS13_GOST profile is used and ECDHE or PSK with ECDHE key + exchange mode is used, the public ephemeral key Q indicated in the + KeyShareEntry.key_exchange field MUST contain the data defined by the + following structure: + + struct { + opaque X[coordinate_length]; + opaque Y[coordinate_length]; + } PlainPointRepresentation; + + where X and Y, respectively, contain the byte representations of x + and y values of the point Q (Q = (x, y)) in the little-endian format + and are specified as follows: + + * X = str_{coordinate_length}(x); + + * Y = str_{coordinate_length}(y). + + The coordinate_length value is defined by the particular elliptic + curve (see Section 6.1.2). + +6.1.2. Values for the TLS Supported Groups Registry + + The "supported_groups" extension is used to indicate the set of the + elliptic curves supported by an endpoint and is defined in + Section 4.2.7 of [RFC8446]. This extension is always contained in + the ClientHello message and optionally in the EncryptedExtensions + message. + + This section defines the following seven elliptic curves: + + enum { + GC256A(0x22), GC256B(0x23), GC256C(0x24), GC256D(0x25), + GC512A(0x26), GC512B(0x27), GC512C(0x28) + } NamedGroup; + + If the TLS13_GOST profile is used and ECDHE or PSK with ECDHE key + exchange mode is used, one of the elliptic curves listed above SHOULD + be used. + + Each curve corresponds to the particular identifier and specifies the + value of coordinate_length parameter (see "cl" column) as follows: + + +===========+========================================+==+=========+ + |Description| Curve Identifier Value |cl|Reference| + +===========+========================================+==+=========+ + |GC256A | id-tc26-gost-3410-2012-256-paramSetA |32|RFC 7836 | + +-----------+----------------------------------------+--+---------+ + |GC256B | id-GostR3410-2001-CryptoPro-A-ParamSet |32|RFC 4357 | + +-----------+----------------------------------------+--+---------+ + |GC256C | id-GostR3410-2001-CryptoPro-B-ParamSet |32|RFC 4357 | + +-----------+----------------------------------------+--+---------+ + |GC256D | id-GostR3410-2001-CryptoPro-C-ParamSet |32|RFC 4357 | + +-----------+----------------------------------------+--+---------+ + |GC512A | id-tc26-gost-3410-12-512-paramSetA |64|RFC 7836 | + +-----------+----------------------------------------+--+---------+ + |GC512B | id-tc26-gost-3410-12-512-paramSetB |64|RFC 7836 | + +-----------+----------------------------------------+--+---------+ + |GC512C | id-tc26-gost-3410-2012-512-paramSetC |64|RFC 7836 | + +-----------+----------------------------------------+--+---------+ + + Table 5 + + Note: The identifier values and the corresponding elliptic curves are + the same as in [RFC9189]. + +6.2. Authentication + + In accordance with [RFC8446], authentication can be performed via a + signature with a certificate or via a symmetric PSK. The server side + is always authenticated; the client side is optionally authenticated. + + PSK-based authentication is performed as a side effect of key + exchange. If the TLS13_GOST profile is used, external PSKs SHOULD be + combined only with mutual authentication (see Section 9). + + Certificate-based authentication is performed via Authentication + messages and an optional CertificateRequest message (sent if client + authentication is required). If the TLS13_GOST profile is used, the + signature schemes used for certificate-based authentication are + defined in Section 5 and Authentication messages are specified in + Sections 6.3.3 and 6.3.4. The CertificateRequest message is + specified in Section 6.3.2. + +6.3. Handshake Messages + + The TLS13_GOST profile specifies the ClientHello, ServerHello, + CertificateRequest, Certificate and CertificateVerify handshake + messages that are described in further detail below. + +6.3.1. Hello Messages + + The ClientHello message is sent when the client first connects to the + server or responds to the HelloRetryRequest message and is specified + in accordance with Section 4.1.2 of [RFC8446]. + + If the TLS13_GOST profile is used, the ClientHello message MUST meet + the following requirements: + + * The ClientHello.cipher_suites field MUST contain the values + defined in Section 4. + + * If server authentication via a certificate is required, the + extension_data field of the "signature_algorithms" extension MUST + contain the values defined in Section 5 that correspond to the + GOST R 34.10-2012 signature algorithm. + + * If server authentication via a certificate is required and the + client uses optional "signature_algorithms_cert" extension, the + extension_data field of this extension SHOULD contain the values + defined in Section 5 that correspond to the GOST R 34.10-2012 + signature algorithm. + + * If the client wants to establish a TLS 1.3 connection using the + ECDHE shared secret, the extension_data field of the + "supported_groups" extension MUST contain the elliptic curve + identifiers defined in Section 6.1.2. + + The ServerHello message is sent by the server in response to the + ClientHello message to negotiate an acceptable set of handshake + parameters based on the ClientHello message and is specified in + accordance with Section 4.1.3 of [RFC8446]. + + If the TLS13_GOST profile is used, the ServerHello message MUST meet + the following requirements: + + * The ServerHello.cipher_suite field MUST contain one of the values + defined in Section 4. + + * If the server decides to establish a TLS 1.3 connection using the + ECDHE shared secret, the extension_data field of the "key_share" + extension MUST contain the elliptic curve identifier and the + public ephemeral key that satisfy the following conditions: + + - The elliptic curve identifier corresponds to the value that was + indicated in the "supported_groups" and the "key_share" + extensions in the ClientHello message. + + - The elliptic curve identifier is one of the values defined in + Section 6.1.2. + + - The public ephemeral key corresponds to the elliptic curve + specified by the KeyShareEntry.group identifier. + +6.3.2. CertificateRequest + + This message is sent when the server requests client authentication + via a certificate and is specified in accordance with Section 4.3.2 + of [RFC8446]. + + If the TLS13_GOST profile is used, the CertificateRequest message + MUST meet the following requirements: + + * The extension_data field of the "signature_algorithms" extension + MUST contain only the values defined in Section 5. + + * If the server uses optional "signature_algorithms_cert" extension, + the extension_data field of this extension SHOULD contain only the + values defined in Section 5. + +6.3.3. Certificate + + This message is sent to convey the endpoint's certificate chain to + the peer and is specified in accordance with Section 4.4.2 of + [RFC8446]. + + If the TLS13_GOST profile is used, the Certificate message MUST meet + the following requirements. + + * Each endpoint's certificate provided to the peer MUST be signed + using the algorithm that corresponds to a signature scheme + indicated by the peer in its "signature_algorithms_cert" + extension, if present (or in the "signature_algorithms" extension, + otherwise). + + * The signature algorithm used for signing certificates SHOULD + correspond to one of the signature schemes defined in Section 5. + +6.3.4. CertificateVerify + + This message is sent to provide explicit proof that the endpoint has + the private key corresponding to the public key indicated in its + certificate and is specified in accordance with Section 4.4.3 of + [RFC8446]. + + If the TLS13_GOST profile is used, the CertificateVerify message MUST + meet the following requirements: + + * The CertificateVerify.algorithm field MUST contain the signature + scheme identifier that corresponds to the value indicated in the + peer's "signature_algorithms" extension and is one of the values + defined in Section 5. + + * The CertificateVerify.signature field contains the sgn value that + is computed as follows: + + sgn = SIGN(d_sign, M), + + where + + - the SIGN function is defined in Section 5.3; + + - d_sign is the sender's long-term private key that corresponds + to the sender's long-term public key Q_sign from the sender's + certificate; + + - the message M is defined in accordance with Section 4.4.3 of + [RFC8446]. + +7.
