Using GOST Cryptographic Algorithms in the Internet Key Exchange

Protocol Version 2 (IKEv2)

Abstract

This document defines a set of cryptographic transforms for use in
the Internet Key Exchange Protocol version 2 (IKEv2). The transforms
are based on Russian cryptographic standard algorithms (called "GOST"
algorithms). Use of GOST ciphers in IKEv2 is defined in RFC 9227.
This document aims to define the use of GOST algorithms for the rest
of the cryptographic transforms used in IKEv2.

This specification was developed to facilitate implementations that
wish to support the GOST algorithms. This document does not imply
IETF endorsement of the cryptographic algorithms used in this
document.

1. Introduction

The Internet Key Exchange Protocol version 2 (IKEv2) defined in
[RFC7296] is an important part of the IP Security (IPsec)
architecture. It is used for the authenticated key exchange and for
the negotiation of various protocol parameters and features.

This document defines a number of transforms for IKEv2, based on
Russian cryptographic standard algorithms (often referred to as
"GOST" algorithms) for hash function, digital signature, and key
exchange method. These definitions are based on the recommendations
established by the Standardisation Technical Committee "Cryptographic information protection", which describe how Russian cryptographic
standard algorithms are used in IKEv2 [GOST-IKEv2]. Along with the
transforms defined in [RFC9227], the transforms defined in this
specification allow for the use of GOST cryptographic algorithms in
IPsec protocols.

This specification was developed to facilitate implementations that
wish to support the GOST algorithms. This document does not imply
IETF endorsement of the cryptographic algorithms used in this
document.

2. Terminology and Notation

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. Overview

Russian cryptographic standard algorithms (GOST algorithms) are a set
of cryptographic algorithms of different types -- ciphers, hash
functions, digital signatures, etc. In particular, Russian
cryptographic standard [GOST3412-2015] defines the "Kuznyechik" and
"Magma" block ciphers (also defined in [RFC7801] and [RFC8891],
respectively). Cryptographic standard [GOST3410-2012] defines the
elliptic curve digital signature algorithm (also defined in
[RFC7091]), while [GOST3411-2012] defines two cryptographic hash
functions with different output lengths (also defined in [RFC6986]).
These hash functions are often referred to as "Streebog" hash
functions, although this is not an official name and is not used in
the provided references. The parameters for the elliptic curves used
in GOST signature and key exchange algorithms are defined in
[RFC7836].

4. IKE SA Protection

IKE Security Association (SA) protection using GOST algorithms is
defined in [RFC9227]. In particular, two transforms of Type 1
(Encryption Algorithm Transform IDs) can be used for IKE SA protection: ENCR_KUZNYECHIK_MGM_KTREE (32) based on the "Kuznyechik"
block cipher and ENCR_MAGMA_MGM_KTREE (33) based on the "Magma" block
cipher, both in Multilinear Galois Mode (MGM).

The information here is provided for convenience. For full details,
please see [RFC9227].

5. Pseudorandom Function

This specification defines a new transform of Type 2 (Pseudorandom
Function Transform IDs): PRF_HMAC_STREEBOG_512 (9). This transform
uses the Pseudorandom Function (PRF) HMAC_GOSTR3411_2012_512 defined
in Section 4.1.2 of [RFC7836]. The PRF uses the GOST R 34.11-2012
("Streebog") hash function with a 512-bit output defined in [RFC6986]
and [GOST3411-2012] with HMAC [RFC2104] construction. The PRF has a
512-bit block size and a 512-bit output length.

6. Shared Key Calculation

This specification defines two new transforms of Type 4 (Key Exchange
Method Transform IDs): GOST3410_2012_256 (33) and GOST3410_2012_512
(34). These transforms use the Elliptic Curve Diffie-Hellman (ECDH)
key exchange algorithm over twisted Edwards curves. The parameters
for these curves are defined in Appendix A.2 of [RFC7836]. In
particular, transform GOST3410_2012_256 uses the id-tc26-gost- 3410-2012-256-paramSetA parameter set and GOST3410_2012_512 uses the id-tc26-gost-3410-2012-512-paramSetC parameter set (both defined in
[RFC7836]).

The shared secret is computed as follows. The initiator randomly
selects its private key d_i from {1,..,q - 1}, where q is the
subgroup order and is a parameter of the selected curve. Then a
public key Q_i is computed as a point on the curve: 

      Q_i = d_i * G

where G is the generator for the selected curve. It is then sent to
the responder. The responder makes the same calculations to get d_r
and Q_r and sends Q_r to the initiator. After peers exchange Q_i and
Q_R, both sides can compute a point on the curve: 

      S = ((m / q) * d_i) * Q_r = ((m / q) * d_r) * Q_i

where m is the group order and is a parameter of the selected curve.
The shared secret K is an x coordinate of S in a little-endian
representation. The size of K is determined by the size of the used
curve and is either 256 or 512 bits.

When the GOST public key is transmitted in the Key Exchange payload
(Section 3.4 of [RFC7296]), it MUST be represented as x coordinate
immediately followed by y coordinate, each in a little-endian
representation. The size of each coordinate is determined by the
size of the used curve and is either 256 or 512 bits, so that the
size of the Key Exchange Data field in the Key Exchange payload is
either 64 or 128 octets.

6.1. Recipient Tests

Upon receiving a peer's public key, implementations MUST check that
the key is actually a point on the curve. Otherwise, the exchange
fails. Implementations MUST check that the calculated public value S
is not an identity element of the curve. If S appears to be the
identity element of the curve, the exchange fails. The
INVALID_SYNTAX notification MAY be sent in these cases.

7. Authentication

IKEv2 allows various authentication methods to be used for IKE SA
establishment. Some methods are tied to a particular algorithm,
while others may be used with different algorithms. This
specification makes no restrictions on using the latter ones with the
GOST algorithms. In particular, "Shared Key Message Integrity Code"
(2), defined in [RFC7296], and "NULL Authentication" (13), defined in
[RFC7619], can be used with GOST algorithms with no changes to the
process of the AUTH payload content calculation.

When the GOST digital signature algorithm is used in IKEv2 for
authentication purposes, the "Digital Signature" (14) authentication
method, defined in [RFC7427], MUST be specified in the AUTH payload.

The GOST digital signature algorithm GOST R 34.10-2012 is defined in
[RFC7091] and [GOST3410-2012]. There are two variants of the GOST
digital signature algorithm -- one over a 256-bit elliptic curve and
the other over a 512-bit key elliptic curve. The signature value, as
defined in [RFC7091] and [GOST3410-2012], consists of two integers: r
and s. The size of each integer is either 256 or 512 bits depending
on the elliptic curve used. The content of the Signature Value field
in the AUTH payload MUST consist of s immediately followed by r, each
in a big-endian representation, so that the size of the field is
either 64 or 128 octets. The AlgorithmIdentifier ASN.1 objects for
the GOST digital signature algorithm are defined in Section 7.2.

7.1. Hash Functions

The GOST digital signature algorithm uses the GOST R 34.11-2012
("Streebog") hash functions defined in [RFC6986] and [GOST3411-2012].
There are two "Streebog" hash functions: one with a 256-bit output
length and the other with a 512-bit output length. The former is
used with the GOST digital signature algorithm over a 256-bit
elliptic curve and the latter over a 512-bit key elliptic curve.

This specification defines two new values for the "IKEv2 Hash
Algorithms" registry: STREEBOG_256 (6) for the GOST hash function
with a 256-bit output length and STREEBOG_512 (7) for the GOST hash
function with a 512-bit output length. These values MUST be included
in the SIGNATURE_HASH_ALGORITHMS notification if a corresponding GOST
digital signature algorithm is supported by the sender and its local
policy allows the use of this algorithm (see Section 4 of [RFC7427]
for details).

7.2. ASN.1 Objects

This section lists GOST digital signature algorithm ASN.1
AlgorithmIdentifier objects in binary form. With GOST digital
signature algorithms, optional parameters in AlgorithmIdentifier
objects are always omitted. These objects are defined in [RFC9215] and [USING-GOST-IN-CERTS] and are provided here for convenience.

7.2.1. id-tc26-signwithdigest-gost3410-12-256

   id-tc26-signwithdigest-gost3410-12-256 OBJECT IDENTIFIER ::=

           algorithms(1) signwithdigest(3) gost3410-12-256(2)}

The optional parameters field must be omitted. 

   Name = id-tc26-signwithdigest-gost3410-12-256
   OID = 1.2.643.7.1.1.3.2
   Length = 12

           algorithms(1) signwithdigest(3) gost3410-12-512(3)}

The optional parameters field must be omitted.

   OID = 1.2.643.7.1.1.3.3
   Length = 12
   0000: 300a 0608 2a85 0307 0101 0303

8. Security Considerations

The security considerations of [RFC7296] and [RFC7427] apply.

The security of GOST elliptic curves is discussed in
[GOST-EC-SECURITY]. The security of the "Streebog" hash functions is
discussed in [STREEBOG-SECURITY]. A second preimage attack on
"Streebog" hash functions is described in [STREEBOG-PREIMAGE] if the
message size exceeds 2^259 blocks. This attack is not relevant to
how "Streebog" hash functions are used in IKEv2.

9. IANA Considerations

IANA has assigned one Transform ID in the "Transform Type 2 -
Pseudorandom Function Transform IDs" registry:

scenarios, peers establish, rekey, and delete an IKE SA and ESP SAs.
The IP addresses of the peers used in both scenarios are the same:

  • initiator's IP address is 10.111.10.171
  • responder's IP address is 10.111.10.45

The test vectors also cover IKE message protection for transforms
defined in [RFC9227]. The keys SK_ei and SK_er are transform keys
(see Section 4.4 of [RFC9227]), and the keys K1i, K2i, K3i, K1r, K2r,
and K3r represent nodes in the key tree for the initiator and
responder correspondently. The leaf keys K3i and K3r are effectively
message protection keys (K_msg in terms of [RFC9227]). MGM nonces
(also known as Initial Counter Nonces) are defined in Section 4.3 of
[RFC9227]. The Initialization Vector (IV) format is defined in
Section 4.2 of [RFC9227], and the Additional Authenticated Data (AAD)
format is defined in Section 4.7 of [RFC9227].

All other keys and entities used in the test vectors are defined in
[RFC7296].

A.1. Scenario 1

In this scenario, peers establish, rekey, and delete an IKE SA and
ESP SAs using the following prerequisites:

  • Peers authenticate each other using a Pre-Shared Key (PSK).
  • Initiator's ID is "IKE-Initiator" of type ID_FQDN.
  • Responder's ID is "IKE-Responder" of type ID_FQDN.
  • No NAT is present between the peers.
  • IKE fragmentation is not used.
  • IKE SA is created with the following transforms:
  • ENCR_KUZNYECHIK_MGM_KTREE
  • PRF_HMAC_STREEBOG_512
  • GOST3410_2012_512
  • ESP SAs are created with the following transforms:
  • ENCR_KUZNYECHIK_MGM_KTREE
  • ESN off

The 256-bit PSK used for authentication: 

   00000000: e2 69 24 cf 15 32 93 47 3a 11 a4 97 a8 a4 5c b3
   00000010: 4e 28 31 ef 0e 28 bb 77 69 69 c6 3c 68 bf e1 0d

This scenario includes four sub-scenarios, which are described below.

A.1.1. Sub-Scenario 1: Establishment of IKE and ESP SAs Using the

IKE_SA_INIT and the IKE_AUTH Exchanges

A.2. Scenario 2

In this scenario, peers establish, rekey, and delete an IKE SA and
ESP SAs using the following prerequisites:

  • Peers authenticate each other using digital signatures.
  • Initiator's ID is "CN=IKE Interop Test Client, O=ELVIS-PLUS, C=RU" of type ID_DER_ASN1_DN:
      00000010: 30 44 31 20 30 1e 06 03 55 04 03 13 17 49 4b 45
      00000020: 20 49 6e 74 65 72 6f 70 20 54 65 73 74 20 43 6c
      00000030: 69 65 6e 74 31 13 30 11 06 03 55 04 0a 13 0a 45
      00000040: 4c 56 49 53 2d 50 4c 55 53 31 0b 30 09 06 03 55
      00000050: 04 06 13 02 52 55
  • Responder's ID is "CN=IKE Interop Test Server, O=ELVIS-PLUS, C=RU" of type ID_DER_ASN1_DN:
      00000010: 30 44 31 20 30 1e 06 03 55 04 03 13 17 49 4b 45
      00000020: 20 49 6e 74 65 72 6f 70 20 54 65 73 74 20 53 65
      00000030: 72 76 65 72 31 13 30 11 06 03 55 04 0a 13 0a 45
      00000040: 4c 56 49 53 2d 50 4c 55 53 31 0b 30 09 06 03 55
      00000050: 04 06 13 02 52 55
  • No NAT is present between the peers, but using UDP encapsulation is forced by the initiator by setting the NAT_DETECTION_SOURCE_IP notification data to all zeroes.
  • IKE fragmentation is used in the IKE_AUTH exchange.
  • IKE SA is created with the following transforms:
  • ENCR_MAGMA_MGM_KTREE
  • PRF_HMAC_STREEBOG_512
  • GOST3410_2012_256
  • ESP SAs are created with the following transforms:
  • ENCR_MAGMA_MGM_KTREE
  • ESN off

The certificates for this scenario were obtained from the public
testing CA service <https://testgost2012.cryptopro.ru/certsrv/>.
