Using ShangMi in the Internet Key Exchange Protocol Version 2 (IKEv2)
draft-guo-ipsecme-ikev2-using-shangmi-00
Abstract
This document defines a set of cryptographic transforms for using in
the Internet Key Exchange Protocol version 2 (IKEv2). The transforms
are based on Chinese cryptographic standard algorithms (called
"ShangMi" or “SM” algorithms).
The use of these algorithms with IKEv2 is not endorsed by the IETF.
The SM algorithms are mandatory in China, so this document provides a
description of how to use the SM algorithms with IKEv2 and specifies
a set of cryptographic transforms so that implementers can produce
interworking implementations.

1. Introduction
This document describes a number of new transforms and a new
authentication method using SM2 signature and SM3 hash function for
IKEv2 ([RFC7296]), based on ISO and Chinese cryptographic standard
algorithms ("SM" algorithms) for encryption, hash function, digital
signature, and key exchange method. With the definition in this
document, the SM algorithms can be used to implement IPSec protocols.
For a more detailed introduction to SM cryptographic algorithms,
please see Section 1.1. These transforms follow the IKEv2
requirements. Specifically, all the encryption transforms use SM4 in
different encryption mode (e.g. CBC mode, Galois/Counter (GCM) mode
or Counter with CBC-MAC (CCM) mode) . The key exchange mechanism
utilizes Elliptic Curve Diffie-Hellman Ephemeral (ECDHE) over the SM2
elliptic curve, and the signature algorithm combines the SM3 hash
function and the SM2 elliptic curve signature scheme.
1.1. The SM Algorithms
Several different SM cryptographic algorithms are used to integrate
with IKEv2, including SM2 for key exchange and authentication, SM4
for encryption, and SM3 as the hash function.
SM2 is a set of cryptographic algorithms based on elliptic curve
cryptography, including a digital signature, public key encryption
and key exchange scheme. In this document, only the SM2 digital
signature algorithm and basic key exchange scheme are involved, which
have already been added to ISO/IEC 14888-3:2018 [ISO-SM2] (as well as
to [GBT.32918.2-2016]). The parameter definition of SM2 is described
in [GBT.32918.5-2017]. SM4 is a block cipher defined in
[GBT.32907-2016] and now is being standardized by ISO to ISO/IEC
18033-3:2010 [ISO-SM4]. SM3 is a hash function that produces an
output of 256 bits. SM3 has already been accepted by ISO in ISO/IEC
10118-3:2018 [ISO-SM3] and has also been described by
[GBT.32905-2016].

3. Transforms Description
3.1. Encryption Transforms
The new encryption transforms introduced in this document add three
encryption algorithms: ENCR_SM4_CBC, ENCR_SM4_GCM and ENCR_SM4_CCM.
ENCR_SM4_CBC is encryption transform based on SM4 for SM4[ISO-SM4]
and [GBT.32907-2016]encryption algorithm using CBC mode.
ENCR_SM4_GCM (Transform ID XX) and ENCR_SM4_CCM (Transform ID XX) are
AEAD transforms based on SM4 cipher in Galois/Counter mode and SM4
cipher in Counter with CBC-MAC mode, respectively. The hash function
for both cipher suites is SM3 ([ISO-SM3]).
3.1.1. ENCR_SM4_CBC
The specification of ENCR_SM4_CBC is as follows: The CBC (Cipher
Block Chaining) mode is defined in [NIST.SP.800-38A] and utilized
with the SM4 algorithm in the following sections. The input
plaintext of SM4-CBC MUST be a multiple of the block size, which is
128-bits in SM4. SM4-CBC requires an additional input, the IV, that
is unpredictable for a particular execution of the encryption
process. The IV does not have to be secret. The IV itself, or
criteria enough to determine it, MAY be transmitted with ciphertext.
A simple test vector of ENCR _SM4_CBC is given in Appendix A of this
document.
3.1.2. ENCR_SM4_GCM
The ENCR_SM4_GCM authenticated encryption algorithm is defined in
[GCM], using SM4 as the block cipher, by providing the key, nonce,
plaintext, and additional associated data to that mode of operation.
An authentication tag conforming to the requirements of IKEv2 as
specified in [RFC5282] MUST be constructed using the partial contents
of the IKEv2 message, starting from the first octet of the Fixed IKE
Header through the last octet of the Payload Header of the Encrypted
Payload (i.e., the fourth octet of the Encrypted Payload). This
includes any payloads that are between the Fixed IKE Header and the
Encrypted Payload. The additional data input that forms the
authentication tag MUST be the partial contents of the IKEv2 message,
starting from the first octet of the Fixed IKE Header through the
last octet of the Payload Header of the Encrypted Payload (i.e., the
fourth octet of the Encrypted Payload). This includes any payloads
that are between the Fixed IKE Header and the Encrypted Payload. The
ENCR_SM4_GCM has four inputs: an SM4 key, an initialization vector
(IV), a plaintext content, and optional additional authenticated data

Internet-Draft Using ShangMi in IKEv2 January 2024
(AAD). ENCR_SM4_GCM generates two outputs: a ciphertext and message
authentication code.
The input and output lengths are as follows:
The SM4 key length is 16 octets.
The max plaintext length is $2^{36} - 31$ octets.
The max AAD length is $2^{61} - 1$ octets.
The nonce length is 12 octets.
The authentication tag length is 16 octets.
The max ciphertext length is $2^{36} - 15$ octets.
The nonce is generated by the party performing the authenticated
encryption operation. Within the scope of any authenticated
encryption key, the nonce value MUST be unique. That is, the set of
nonce values used with any given key MUST NOT contain any duplicates.
Using the same nonce for two different messages encrypted with the
same key destroys the security properties of GCM mode.
3.1.3. ENCR_SM4_CCM
The ENCR_SM4_CCM authenticated encryption algorithm is defined in
[CCM] using SM4 as the block cipher. The generation of the
authentication tag MUST conform to IKEv2 (See [RFC5282]) as described
in the above paragraph. ENCR_SM4_CCM has four inputs: an SM4 key, a
nonce, a plaintext, and optional additional authenticated data (AAD).
ENCR_SM4_CCM generates two outputs: a ciphertext and a message
authentication code.
The input and output lengths are as follows:
The SM4 key length is 16 octets.
The max plaintext length is $2^{24} - 1$ octets.
The max AAD length is $2^{64} - 1$ octets.
The max ciphertext length is $2^{24} + 15$ octets
To have a common set of terms for ENCR _SM4_GCM and ENCR _SM4_CCM,
the ENCR _SM4_GCM IV is referred to as a nonce in the remainder of
this document.

A simple test vector of ENCR _SM4_GCM and ENCR _SM4_CCM is given in
Appendix A of this document.
3.2. Pseudorandom Function Transform
This specification defines a new transform of Type 2 (Pseudorandom
Function Transform IDs):
PRF_HMAC_SM3 (Transform ID XX). The PRF uses the SM3 hash function
with a 256-bit output defined in [ISO-SM3] and [GBT.32905-2016] and
with HMAC construction. The PRF has a 256-bit block size and a
256-bit output length.
PRF_ HMAC_SM3 is hash-based message authentication code (or HMAC),
which is defined in [RFC2104], using SM3 as the hash function. The
PRF_ HMAC_SM3 has two inputs: HMAC key and the plaintext. The output
of PRF_ HMAC_SM3 is 256 bits.
3.3. Integrity Algorithm Transform
This specification defines a new transform of Type 3 (Integrity
Algorithm Transform IDs):
AUTH_HMAC_SM3 (Transform ID XX). The MAC uses the SM3 hash function
with a 256-bit output defined in [ISO-SM3] and [GBT.32905-2016] and
with HMAC construction. AUTH_HMAC_SM3 is specified as described in
2.2.
While no fixed key length is specified in [RFC2104], this
specification requires that when used as an integrity/authentication
algorithm, a fixed key length equal to the output length of the hash
functions MUST be supported, and key lengths other than the output
length of the associated hash function MUST NOT be supported. These
key length restrictions are the same with HMAC-SHA-256 (see [RFC4868]
Sec2.1.1).
3.4. Key Exchange Method Transform
This specification defines one new transforms of Type 4 (Key Exchange
Method Transform IDs): curveSM2. This transform uses a fixed
elliptic curve parameter set defined in [GBT.32918.5-2017]. The
specification of curveSM2 is defined in clause 3.2 of RFC 8998
[RFC8998] as ”curveSM2”, which is used to define new cipher suites
for TLS 1.3 protocol.
Guo, et al. Expires 1 August 2024 [Page 6]
Internet-Draft Using ShangMi in IKEv2 January 2024
Implementations of the key exchange mechanism defined in this
document MUST conform to what [GBT.32918.5-2017] requires; that is to
say, the only valid elliptic curve parameter set for the ”curveSM2”
key exchange is defined as follows:
curveSM2: A prime field of 256 bits.
$y^2 = x^3+ ax + b$
p = FFFFFFFE FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF 00000000 FFFFFFFF

4. Authentication Method
The Chinese government requires the use of the SM2 signature
algorithm. This section specifies the use of the SM2 signature
algorithm as the authentication method for IKEv2 protocol.
The SM2 signature algorithm is defined in [ISO-SM2]. The SM2
signature algorithm is based on elliptic curves. The SM2 signature
algorithm uses a fixed elliptic curve parameter set defined in
[GBT.32918.5-2017]. This curve is named "curveSM2" as defined in
section 2.4.
Implementations of the signature scheme mechanism defined in this
document MUST conform to what [GBT.32918.5-2017] requires.
5. Hash Algorithms
The SM2 digital signature algorithm uses the SM3 hash functions
defined in [ISO-SM3] and [GBT.32905-2016]. This specification
defines one new value for the "IKEv2 Hash Algorithms" registry: SM3
(value XX) for the SM3 hash function with a 256-bit output length.
Guo, et al. Expires 1 August 2024 [Page 7]
Internet-Draft Using ShangMi in IKEv2 January 2024
The specification of SM3 is defined as follows:
The SM3 algorithm is intended to address multiple use cases for
commercial cryptography, including, but not limited to: - the use of
digital signatures and their verification; - the generation and
verification of message authenticity codes; as well as - the
generation of random numbers.
SM3 has a Merkle-Damgard construction and is similar to SHA-2
[NIST.FIPS.180-4]of the MD4 [RFC6150] family, with the addition of
several strengthening features including a more complex step function
and stronger message dependency than SHA-256 [RFC6234]. SM3 produces
an output hash value of 256 bits long, based on 512-bit input message
blocks, on input lengths up to 2^(m) [GBT.32905-2016]. This details
the SM3 algorithm and its internal steps can be find in
[GBT.32905-2016].
6. IANA Considerations
IANA maintains a registry called "Internet Key Exchange Version 2
(IKEv2) Parameters" with subregistries like "Transform Type Values",
“IKEv2 Authentication Method” and “IKEv2 Hash Algorithms”.
This document describes 3 new encryption transforms, 1 pseudorandom
function transform, 1 integrity algorithm transform, 1 key exchange
method transform and a new authentication method using SM2 signature
and SM3 hash function for IKEv2 ([RFC7296]).
IANA is requested to assign 3 new Transform IDs to the "Transform
Type 1 - Encryption Algorithm Transform IDs" subregistry,

7. Security Considerations
At the time of writing, there are no known weak keys for SM
cryptographic algorithms SM2, SM3 and SM4, and no security issues
have been found for these algorithms.
A related work [CQCY21] analyzed the security of SM2 algorithm , and
the cryptanalysis results shows that SM2 is existentially unforgeable
against adaptively chosen-message attacks in the generic group model
if the underlying hash function is uniform and collision-resistant
and the underlying conversion function is almost-invertible.
Besides, SM2 is secure against the generalized key substitution
attacks if the underlying hash functions H and h are modeled as non-
programmable random oracles (NPROs) [ZYZC15].
As a result of the increasing prevalence and exploitation of side-
channel attacks ([JYW20], [WDW18], [LZHZ18]), the SM4 algorithm is
now confronted with significant threats when utilized in smart cards
and other cryptographic devices. However, these attacks can be
mitigated through the implementation of side-channel protection. On
the other hand, the classic cryptanalysis techniques are not
applicable to the entire cipher and are impractical, do not
compromise the overall security of SM4.
