  • V. Smyslov
Informational

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 [] 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 [], 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 [] [] 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 [] and [], respectively). Cryptographic standard [GOST3410-2012] defines the elliptic curve digital signature algorithm (also defined in []), while [GOST3411-2012] defines two cryptographic hash functions with different output lengths (also defined in []). 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 [].

4. IKE SA Protection

IKE Security Association (SA) protection using GOST algorithms is defined in []. 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 [].

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 of []. The PRF uses the GOST R 34.11-2012 ("Streebog") hash function with a 512-bit output defined in [] and [GOST3411-2012] with HMAC [] 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 of []. 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 []).

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 ( of []), 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 [], and "NULL Authentication" (13), defined in [], 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 [], MUST be specified in the AUTH payload.

The GOST digital signature algorithm GOST R 34.10-2012 is defined in [] 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 [] 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 [] 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 of [] 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 [] and [USING-GOST-IN-CERTS] and are provided here for convenience.

8. Security Considerations

The security considerations of [] and [] 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 2259 blocks. This attack is not relevant to how "Streebog" hash functions are used in IKEv2.

Appendix A. Test Vectors

This appendix contains test vectors for two scenarios. The test vectors were borrowed from [GOST-IKEv2-TESTVECTORS]. In both 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 []. The keys SK_ei and SK_er are transform keys (see of []), 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 []). MGM nonces (also known as Initial Counter Nonces) are defined in of []. The Initialization Vector (IV) format is defined in of [], and the Additional Authenticated Data (AAD) format is defined in of [].

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

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.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/>.

The initiator's certificate private key (little endian):
