Abstract

   This document defines a set of cryptographic transforms for use in
   the Internet Key Exchange version 2 (IKEv2) protocol.  The transforms
   are based on Russian cryptographic standard algorithms (GOST).

1.  Introduction

   This document defines a number of transforms for the Internet Key
   Exchange version 2 (IKEv2) [RFC7296].  These transforms are based on
   Russian cryptographic standard algorithms (often called "GOST"
   algorithms) for hash function, digital signature and key exchange
   method.  Along with transforms defined in [I-D.smyslov-esp-gost], the
   transforms defined in this specification allow using GOST
   cryptographic algorithms in IPsec protocols.

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 (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 block ciphers
   "Kuznyechik" (also defined in [RFC7801]) and "Magma" (also defined in
   [I-D.dolmatov-magma]).  Cryptographic standard [GOST3410-2012]
   defines elliptic curve digital signature algorithm (also defined in
