RFC 4490 Using GOST with CMS May 2006
1. Introduction
The Cryptographic Message Syntax [CMS] is used for digital signature,
digest, authentication, and encryption of arbitrary message contents.
This companion specification describes the use of cryptographic
algorithms GOST 28147-89 [GOST28147], GOST R 34.10-94 [GOST3431095,
GOSTR341094], GOST R 34.10-2001 [GOST3431004, GOSTR341001], and GOST
R 34.11-94 [GOST3431195, GOSTR341194] in CMS, as proposed by the
CRYPTO-PRO Company for the "Russian Cryptographic Software
Compatibility Agreement" community. This document does not describe
these cryptographic algorithms; they are defined in corresponding
national standards.
The CMS values are generated using ASN.1 [X.208-88], using BER
encoding [X.209-88]. This document specifies the algorithm
identifiers for each algorithm, including ASN.1 for object
identifiers and any associated parameters.
The fields in the CMS employed by each algorithm are identified.
1.1. Terminology
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in [RFC2119].
2. Message Digest Algorithms
This section specifies the conventions for using the digest algorithm
GOST R 34.11-94 employed by CMS.
Digest values are located in the DigestedData digest field and the
Message Digest authenticated attribute. In addition, digest values
are input to signature algorithms.
2.1. Message Digest Algorithm GOST R 34.11-94
The hash function GOST R 34.11-94 has been developed by "GUBS of
Federal Agency Government Communication and Information" and "All-
Russian Scientific and Research Institute of Standardization". The
algorithm GOST R 34.11-94 produces a 256-bit hash value of the
arbitrary finite bit-length input. This document does not contain
the full GOST R 34.11-94 specification, which can be found in
[GOSTR341194] in Russian. [Schneier95], ch. 18.11, p. 454, contains
a brief technical description in English.
Leontiev & Chudov Standards Track [Page 3]
RFC 4490 Using GOST with CMS May 2006
The hash algorithm GOST R 34.11-94 has the following identifier:
id-GostR3411-94 OBJECT IDENTIFIER ::=
{ iso(1) member-body(2) ru(643) rans(2) cryptopro(2)
gostr3411(9) }
The AlgorithmIdentifier parameters field MUST be present, and the
parameters field MUST contain NULL. Implementations MAY accept the
GOST R 34.11-94 AlgorithmIdentifiers with absent parameters as well
as NULL parameters.
This function is always used with default parameters id-GostR3411-
94-CryptoProParamSet (see Section 8.2 of [CPALGS]).
When the Message Digest authenticated attribute is present, the
DigestedData digest contains a 32-byte digest in little-endian
representation:
GostR3411-94-Digest ::= OCTET STRING (SIZE (32))
3. Signature Algorithms
This section specifies the CMS procedures for the GOST R 34.10-94 and
GOST R 34.10-2001 signature algorithms.
Signature algorithm identifiers are located in the SignerInfo
signatureAlgorithm field of SignedData. Also, signature algorithm
identifiers are located in the SignerInfo signatureAlgorithm field of
countersignature attributes.
Signature values are located in the SignerInfo signature field of
SignedData. Also, signature values are located in the SignerInfo
signature field of countersignature attributes.
3.1. Signature Algorithm GOST R 34.10-94
GOST R 34.10-94 has been developed by "GUBS of Federal Agency
Government Communication and Information" and "All-Russian Scientific
and Research Institute of Standardization". This signature algorithm
MUST be used conjointly with the GOST R 34.11-94 message digest
algorithm. This document does not contain the full GOST R 34.10-94
specification, which is fully described in [GOSTR341094] in Russian;
and a brief description in English can be found in [Schneier95], ch.
20.3, p. 495.
The GOST R 34.10-94 signature algorithm has the following public key
algorithm identifier:
Leontiev & Chudov Standards Track [Page 4]
RFC 4490 Using GOST with CMS May 2006
id-GostR3410-94-signature OBJECT IDENTIFIER ::= id-GostR3410-94
id-GostR3410-94 is defined in Section 2.3.1 of [CPPK].
The signature algorithm GOST R 34.10-94 generates a digital signature
in the form of two 256-bit numbers, r' and s. Its octet string
representation consists of 64 octets, where the first 32 octets
contain the big-endian representation of s and the second 32 octets
contain the big-endian representation of r'.
GostR3410-94-Signature ::= OCTET STRING (SIZE (64))
3.2. Signature Algorithm GOST R 34.10-2001
GOST R 34.10-2001 has been developed by "GUBS of Federal Agency
Government Communication and Information" and "All-Russian Scientific
and Research Institute of Standardization". This signature algorithm
MUST be used conjointly with GOST R 34.11-94. This document does not
contain the full GOST R 34.10-2001 specification, which is fully
described in [GOSTR341001].
The signature algorithm GOST R 34.10-2001 has the following public
key algorithm identifier:
id-GostR3410-2001-signature OBJECT IDENTIFIER ::= id-GostR3410-2001
id-GostR3410-2001 is defined in Section 2.3.2 of [CPPK].
The signature algorithm GOST R 34.10-2001 generates a digital
signature in the form of two 256-bit numbers, r and s. Its octet
string representation consists of 64 octets, where the first 32
octets contain the big-endian representation of s and the second 32
octets contain the big-endian representation of r.
GostR3410-2001-Signature ::= OCTET STRING (SIZE (64))
4. Key Management Algorithms
This chapter describes the key agreement and key transport
algorithms, based on the VKO GOST R 34.10-94 and VKO GOST R 34.10-
2001 key derivation algorithms, and the CryptoPro and GOST 28147-89
key wrap algorithms, described in [CPALGS]. They MUST be used only
with the content encryption algorithm GOST 28147-89, defined in
Section 5 of this document.
Leontiev & Chudov Standards Track [Page 5]
RFC 4490 Using GOST with CMS May 2006
4.1. Key Agreement Algorithms
This section specifies the conventions employed by CMS
implementations that support key agreement using both the VKO GOST R
34.10-94 and VKO GOST R 34.10-2001 algorithms, described in [CPALGS].
Key agreement algorithm identifiers are located in the EnvelopedData
RecipientInfos KeyAgreeRecipientInfo keyEncryptionAlgorithm and
AuthenticatedData RecipientInfos KeyAgreeRecipientInfo
keyEncryptionAlgorithm fields.
Wrapped content-encryption keys are located in the EnvelopedData
RecipientInfos KeyAgreeRecipientInfo RecipientEncryptedKeys
encryptedKey field. Wrapped message-authentication keys are located
in the AuthenticatedData RecipientInfos KeyAgreeRecipientInfo
RecipientEncryptedKeys encryptedKey field.
4.1.1. Key Agreement Algorithms Based on GOST R 34.10-94/2001 Public
Keys
The EnvelopedData RecipientInfos KeyAgreeRecipientInfo field is used
as follows:
The version MUST be 3.
The originator MUST be the originatorKey alternative. The
originatorKey algorithm field MUST contain the object identifier
id-GostR3410-94 or id-GostR3410-2001 and corresponding parameters
(defined in Sections 2.3.1, 2.3.2 of [CPPK]).
The originatorKey publicKey field MUST contain the sender's public
key.
keyEncryptionAlgorithm MUST be the id-GostR3410-94-CryptoPro-ESDH
or the id-GostR3410-2001-CryptoPro-ESDH algorithm identifier,
depending on the recipient public key algorithm. The algorithm
identifier parameter field for these algorithms is
KeyWrapAlgorithm, and this parameter MUST be present. The
KeyWrapAlgorithm denotes the algorithm and parameters used to
encrypt the content-encryption key with the pairwise key-
encryption key generated using the VKO GOST R 34.10-94 or the VKO
GOST R 34.10-2001 key agreement algorithms.
The algorithm identifiers and parameter syntax is:
id-GostR3410-94-CryptoPro-ESDH OBJECT IDENTIFIER ::=
{ iso(1) member-body(2) ru(643) rans(2) cryptopro(2)
gostR3410-94-CryptoPro-ESDH(97) }
Leontiev & Chudov Standards Track [Page 6]
RFC 4490 Using GOST with CMS May 2006
id-GostR3410-2001-CryptoPro-ESDH OBJECT IDENTIFIER ::=
{ iso(1) member-body(2) ru(643) rans(2) cryptopro(2)
gostR3410-2001-CryptoPro-ESDH(96) }

The CryptoPro Key Wrap algorithm is described in Sections 6.3 and
6.4 of [CPALGS].
When keyEncryptionAlgorithm is id-GostR3410-2001-CryptoPro-ESDH,
KeyWrapAlgorithm algorithm MUST be either the id-Gost28147-89-
CryptoPro-KeyWrap or id-Gost28147-89-None-KeyWrap algorithm
identifier.
id-Gost28147-89-None-KeyWrap OBJECT IDENTIFIER ::=
{ iso(1) member-body(2) ru(643) rans(2) cryptopro(2)
keyWrap(13) none(0) }
The GOST 28147-89 Key Wrap algorithm is described in Sections 6.1
and 6.2 of [CPALGS].
KeyWrapAlgorithm algorithm parameters MUST be present. The syntax
for KeyWrapAlgorithm algorithm parameters is
Gost28147-89-KeyWrapParameters ::=
SEQUENCE {
encryptionParamSet Gost28147-89-ParamSet,
ukm OCTET STRING (SIZE (8)) OPTIONAL
}
Gost28147-89-ParamSet ::= OBJECT IDENTIFIER
Gost28147-89-KeyWrapParameters ukm MUST be absent.
KeyAgreeRecipientInfo ukm MUST be present and contain eight
octets.
encryptedKey MUST encapsulate Gost28147-89-EncryptedKey, where
maskKey MUST be absent.
Leontiev & Chudov Standards Track [Page 7]
RFC 4490 Using GOST with CMS May 2006
Gost28147-89-EncryptedKey ::= SEQUENCE {
encryptedKey Gost28147-89-Key,
maskKey [0] IMPLICIT Gost28147-89-Key
OPTIONAL,
macKey Gost28147-89-MAC
}
Using the secret key corresponding to the originatorKey publicKey and
the recipient's public key, the algorithm VKO GOST R 34.10-94 or VKO
GOST R 34.10-2001 (described in [CPALGS]) is applied to produce the
KEK.
Then the key wrap algorithm, specified by KeyWrapAlgorithm, is
applied to produce CEK_ENC, CEK_MAC, and UKM. Gost28147-89-
KeyWrapParameters encryptionParamSet is used for all encryption
operations.
The resulting encrypted key (CEK_ENC) is placed in the Gost28147-89-
EncryptedKey encryptedKey field, its mac (CEK_MAC) is placed in the
Gost28147-89-EncryptedKey macKey field, and UKM is placed in the
KeyAgreeRecipientInfo ukm field.
4.2. Key Transport Algorithms
This section specifies the conventions employed by CMS
implementations that support key transport using both the VKO GOST R
34.10-94 and VKO GOST R 34.10-2001 algorithms, described in [CPALGS].
Key transport algorithm identifiers are located in the EnvelopedData
RecipientInfos KeyTransRecipientInfo keyEncryptionAlgorithm field.
Key transport encrypted content-encryption keys are located in the
EnvelopedData RecipientInfos KeyTransRecipientInfo encryptedKey
field.
4.2.1. Key Transport Algorithm Based on GOST R 34.10-94/2001 Public
Keys
The EnvelopedData RecipientInfos KeyTransRecipientInfo field is used
as follows:
The version MUST be 0 or 3.
keyEncryptionAlgorithm and parameters MUST be identical to the
recipient public key algorithm and parameters.
Leontiev & Chudov Standards Track [Page 8]
RFC 4490 Using GOST with CMS May 2006
encryptedKey encapsulates GostR3410-KeyTransport, which consists
of encrypted content-encryption key, its MAC, GOST 28147-89
algorithm parameters used for key encryption, the sender's
ephemeral public key, and UKM (UserKeyingMaterial; see [CMS],
Section 10.2.6).
transportParameters MUST be present.
ephemeralPublicKey MUST be present and its parameters, if present,
MUST be equal to the recipient public key parameters;
GostR3410-KeyTransport ::= SEQUENCE {
sessionEncryptedKey Gost28147-89-EncryptedKey,
transportParameters
[0] IMPLICIT GostR3410-TransportParameters OPTIONAL
}
GostR3410-TransportParameters ::= SEQUENCE {
encryptionParamSet OBJECT IDENTIFIER,
ephemeralPublicKey [0] IMPLICIT SubjectPublicKeyInfo OPTIONAL,
ukm OCTET STRING
}
Using the secret key corresponding to the GostR3410-
TransportParameters ephemeralPublicKey and the recipient's public
key, the algorithm VKO GOST R 34.10-94 or VKO GOST R 34.10-2001
(described in [CPALGS]) is applied to produce the KEK.
Then the CryptoPro key wrap algorithm is applied to produce CEK_ENC,
CEK_MAC, and UKM. GostR3410-TransportParameters encryptionParamSet
is used for all encryption operations.
The resulting encrypted key (CEK_ENC) is placed in the Gost28147-89-
EncryptedKey encryptedKey field, its mac (CEK_MAC) is placed in the
Gost28147-89-EncryptedKey macKey field, and UKM is placed in the
GostR3410-TransportParameters ukm field.
5. Content Encryption Algorithms
This section specifies the conventions employed by CMS
implementations that support content encryption using GOST 28147-89.
Content encryption algorithm identifiers are located in the
EnvelopedData EncryptedContentInfo contentEncryptionAlgorithm and the
EncryptedData EncryptedContentInfo contentEncryptionAlgorithm fields.
Leontiev & Chudov Standards Track [Page 9]
RFC 4490 Using GOST with CMS May 2006
Content encryption algorithms are used to encipher the content
located in the EnvelopedData EncryptedContentInfo encryptedContent
field and the EncryptedData EncryptedContentInfo encryptedContent
field.
5.1. Content Encryption Algorithm GOST 28147-89
This section specifies the use of GOST 28147-89 algorithm for data
encipherment.
GOST 28147-89 is fully described in [GOST28147] (in Russian).
This document specifies the following object identifier (OID) for
this algorithm:
id-Gost28147-89 OBJECT IDENTIFIER ::=
{ iso(1) member-body(2) ru(643) rans(2) cryptopro(2)
gost28147-89(21) }
Algorithm parameters MUST be present and have the following
structure:
Gost28147-89-Parameters ::=
SEQUENCE {
iv Gost28147-89-IV,
encryptionParamSet OBJECT IDENTIFIER
}
Gost28147-89-IV ::= OCTET STRING (SIZE (8))
encryptionParamSet specifies the set of corresponding Gost28147-89-
ParamSetParameters (see Section 8.1 of [CPALGS])
6. MAC Algorithms
This section specifies the conventions employed by CMS
implementations that support the message authentication code (MAC)
based on GOST R 34.11-94.
MAC algorithm identifiers are located in the AuthenticatedData
macAlgorithm field.
MAC values are located in the AuthenticatedData mac field.
6.1. HMAC with GOST R 34.11-94
HMAC_GOSTR3411 (K,text) function is based on hash function GOST R
34.11-94, as defined in Section 3 of [CPALGS].
Leontiev & Chudov Standards Track [Page 10]
RFC 4490 Using GOST with CMS May 2006
This document specifies the following OID for this algorithm:
id-HMACGostR3411-94 OBJECT IDENTIFIER ::=
{ iso(1) member-body(2) ru(643) rans(2) cryptopro(2)
hmacgostr3411(10) }
This algorithm has the same parameters as the GOST R 34.11-94 digest
algorithm and uses the same OIDs for their identification (see
[CPPK]).
7. Use with S/MIME
This section defines the use of the algorithms defined in this
document with S/MIME [RFC3851].
7.1. Parameter micalg
When using the algorithms defined in this document, micalg parameter
SHOULD be set to "gostr3411-94"; otherwise, it MUST be set to
"unknown".
7.2. Attribute SMIMECapabilities
The SMIMECapability value that indicates support for the GOST R
34.11-94 digest algorithm is the SEQUENCE with the capabilityID field
containing the object identifier id-GostR3411-94 and no parameters.
The DER encoding is:
30 08 06 06 2A 85 03 02 02 09
The SMIMECapability value that indicates support for the GOST
28147-89 encryption algorithm is the SEQUENCE with the capabilityID
field containing the object identifier id-Gost28147-89 and no
parameters. The DER encoding is:
30 08 06 06 2A 85 03 02 02 15
If the sender wishes to indicate support for a specific parameter
set, SMIMECapability parameters MUST contain the Gost28147-89-
Parameters structure. Recipients MUST ignore the Gost28147-89-
Parameters iv field and assume that the sender supports the
parameters specified in the Gost28147-89-Parameters
encryptionParamSet field.
The DER encoding for the SMIMECapability, indicating support for GOST
28147-89 with id-Gost28147-89-CryptoPro-A-ParamSet (see [CPALGS]),
is:
Leontiev & Chudov Standards Track [Page 11]
RFC 4490 Using GOST with CMS May 2006
30 1D 06 06 2A 85 03 02 02 15 30 13 04 08 00 00
00 00 00 00 00 00 06 07 2A 85 03 02 02 1F 01
8. Security Considerations
Conforming applications MUST use unique values for ukm and iv.
Recipients MAY verify that ukm and iv, specified by the sender, are
unique.
It is RECOMMENDED that software applications verify that signature
values, subject public keys, and algorithm parameters conform to
[GOSTR341001] and [GOSTR341094] standards prior to their use.
Cryptographic algorithm parameters affect algorithm strength. The
use of parameters not listed in [CPALGS] is NOT RECOMMENDED (see the
Security Considerations section of [CPALGS]).
Use of the same key for signature and key derivation is NOT
RECOMMENDED. When signed CMS documents are used as an analogue to a
manual signing, in the context of Russian Federal Electronic Digital
Signature Law [RFEDSL], signer certificate MUST contain the keyUsage
extension, it MUST be critical, and keyUsage MUST NOT include
keyEncipherment or keyAgreement (see [PROFILE], Section 4.2.1.3).
Application SHOULD be submitted for examination by an authorized
agency in appropriate levels of target_of_evaluation (TOE), according
to [RFEDSL], [RFLLIC], and [CRYPTOLIC].
9. Examples
Examples here are stored in the same format as the examples in
[RFC4134] and can be extracted using the same program.
If you want to extract without the program, copy all the lines
between the "|>" and "|<" markers, remove any page breaks, and remove
the "|" in the first column of each line. The result is a valid
Base64 blob that can be processed by any Base64 decoder.
9.1. Signed Message
This message is signed using the sample certificate from Section 4.2
of [CPPK]. The public key (x,y) from the same section can be used to
verify the message signature.
