1. 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.

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.

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).
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 |
+===========================================+======================+

Table 1
4.1.3. SNMAX Parameter

the same traffic key material (sender_write_key and sender_write_iv)
and is defined by each cipher suite as follows:
+===========================================+==================+
| CipherSuites | SNMAX |
+===========================================+==================+
| TLS_GOSTR341112_256_WITH_KUZNYECHIK_MGM_L | SNMAX = 2^64 - 1 |

+-------------------------------------------+------------------+
Table 2
4.2. Hash Algorithm
The Hash algorithm is used for the key derivation process (see
Section 7.1 of [
RFC8446]), Finished message calculation (see
Section 4.4.4 of [
RFC8446]), Transcript-Hash function computation
(see Section 4.4.1 of [
RFC8446]), Pre-Shared Key (PSK) binder value
calculation (see Section 4.2.11.2 of [
RFC8446]), external re-keying
approach (see
Section 4.1.2), and other purposes.
If a TLS13_GOST cipher suite is negotiated, the Hash algorithm
MUST be the GOST R 34.11-2012 hash algorithm [
RFC6986] with a 32-byte
(256-bit) hash value.
5. Signature Scheme Definition
This section defines the following seven TLS13_GOST signature
schemes:
enum {
gostr34102012_256a(0x0709),
gostr34102012_256b(0x070A),
gostr34102012_256c(0x070B),
gostr34102012_256d(0x070C),
gostr34102012_512a(0x070D),
gostr34102012_512b(0x070E),
gostr34102012_512c(0x070F)
} SignatureScheme;
One of the TLS13_GOST signature schemes listed above
SHOULD be used
with the TLS13_GOST profile.
Each signature scheme specifies a pair consisting of the signature
algorithm (see
Section 5.1) and the elliptic curve (see
Section 5.2).
The procedure to calculate the signature value using TLS13_GOST
signature schemes is defined in
Section 5.3.
5.1. Signature Algorithm

schemes are defined as follows:

Table 4
5.3. SIGN Function
If the TLS13_GOST signature scheme is used, the signature value in
the CertificateVerify message (see
Section 6.3.4)
MUST be calculated
using the SIGN function defined as follows:
+-----------------------------------------------------+
| SIGN(d_sign, M) |
|-----------------------------------------------------|
| Input: |
| - the sign key d_sign: 0 < d_sign < q; |
| - the byte string M in B*. |
| Output: |
| - signature value sgn in B_{2*l}. |
|-----------------------------------------------------|
| 1. (r, s) = SIGNGOST(d_sign, M) |
| 2. Return str_l(r) | str_l(s). |
|-----------------------------------------------------+
where
* q is the subgroup order of the group of points of the elliptic
curve;
* l is defined as follows:
- l = 32 for the gostr34102012_256a, gostr34102012_256b,
gostr34102012_256c, and gostr34102012_256d signature schemes;
- l = 64 for the gostr34102012_512a, gostr34102012_512b, and
gostr34102012_512c signature schemes;
* SIGNGOST is an algorithm that takes a private key d_sign and a
message M as an input and returns a pair of integers (r, s) that
is calculated during the signature generation process in
accordance with the GOST R 34.10-2012 signature algorithm (see
Section 6.1 of [
RFC7091]).
Note: The signature value sgn is the concatenation of two strings
that are byte representations of r and s values in the little-endian
format.
6. Key Exchange and Authentication
The key exchange and authentication process for using the TLS13_GOST
profile is defined in Sections
6.1,
6.2, and
6.3.
6.1. Key Exchange
The TLS13_GOST profile supports three basic key exchange modes that
are defined in [
RFC8446]: Ephemeral Elliptic Curve Diffie-Hellman
(ECDHE), PSK-only, and PSK with ECDHE.
Note: In accordance with [
RFC8446], TLS 1.3 also supports key
exchange modes based on the Diffie-Hellman protocol over finite
fields. 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|
+===========+========================================+==+=========+

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.
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].

+--------------------+--------------------------------------------+
Table 8
The client should be prepared to handle any of them correctly if the
corresponding signature scheme is included in the
"signature_algorithms" or "signature_algorithms_cert" extensions.
9. Security Considerations
In order to create an efficient and side-channel resistant
implementation while using the TLSTREE algorithm, the functions
KDF_j, j = 1, 2, 3,
SHOULD be called only when necessary (when the
record sequence number seqnum reaches such a value that seqnum & C_j
!= (seqnum - 1) & C_j). Otherwise, the previous value should be
used.

A.2. Example 2
Test examples are given for the following instance of the TLS13_GOST
profile:
1. Full TLS Handshake is used.
2. PSK with ECDHE key exchange mode is used. The elliptic curve
GC256B is used for ECDHE shared secret calculation.
3. Authentication is used on the server and client sides. The
external PSK is used for the mutual authentication.
4. TLS_GOSTR341112_256_WITH_MAGMA_MGM_L cipher suite is negotiated.
5. Four Application Data records are sent during the operation of
the Record protocol. The sequence numbers are selected to
demonstrate the operation of the TLSTREE function.
6. Alert protocol is used for closure of the connection.
