This specification extends [RFC3279], "Algorithms and Identifiers for the Internet X.509 Public Key Infrastructure Certificate and Certificate Revocation List (CRL) Profile" and, correspondingly, [RFC3280], "Internet X.509 Public Key Infrastructure: Certificate and Certificate Revocation List (CRL) Profile". All implementations of this specification MUST also satisfy the requirements of [RFC3280]. This specification defines the content of the signatureAlgorithm, signatureValue, signature, and subjectPublicKeyInfo fields within Internet X.509 certificates and CRLs. Leontiev & Shefanovski Informational [Page 2] Internet-Draft Using GOST with PKIX February 2005 This document defines the use of one-way hash-function GOST R 34.11-94 [GOST3411] with digital signatures.

This document also defines the contents of the subjectPublicKeyInfo field for Internet X.509 certificates. For each algorithm, the appropriate alternatives for the keyUsage extension are provided. This specification describes encoding formats for public keys used with the following cryptographic algorithms: * GOST R 34.10-94 [GOST341094]; * GOST R 34.10-2001 [GOST34102001]; * Key derivation algorithm VKO GOST R 34.10-94 [CPALGS]; * Key derivation algorithm VKO GOST R 34.10-2001 [CPALGS]; ASN.1 modules, including all the definitions used in this document can be found in [CPALGS]. 2 Algorithm Support This section is an overview of cryptographic algorithms, that may be used within the Internet X.509 certificates and CRL profile [RFC3280]. It describes one-way hash functions and digital signature algorithms, that may be used to sign certificates and CRLs, and identifies OIDs and ASN.1 encoding for public keys contained in a certificate. The conforming CAs and/or applications MUST fully support digital signatures and public keys for at least one of the specified algorithms. 2.1 One-way Hash Function This section identifies the use of one-way, collision free hash function GOST R 34.11-94 - the only one that can be used in digital signature algorithms GOST R 34.10-94/2001. The data that is hashed for certificates and CRL signing is fully described in [RFC3280]. 2.1.1 One-way Hash Function GOST R 34.11-94 GOST R 34.11-94 has been developed by "GUBS of Federal Agency Government Communication and Information" and "All-Russian Scientific Leontiev & Shefanovski Informational [Page 3] Internet-Draft Using GOST with PKIX February 2005 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 GOST R 34.11-94 full specification, which can be found in [GOSTR3411] in Russian. It's brief technical description in english can be found in [Schneier95], ch. 18.11, p. 454. This function is always used with default parameter set gostR3411CryptoProParamSetAI (see section 8.2 of [CPALGS]). 2.2 Signature Algorithms Conforming CAs may use GOST R 34.10-94 or GOST R 34.10-2001 signature algorithms to sign certificates and CRLs. The signatureAlgorithm field of Certificate or CertificateList indicates the signature algorithm ID, and associated parameters. This section also defines algorithm identifiers and parameters that MUST be used in the signatureAlgorithm field in a Certificate or CertificateList. Signature algorithms are always used conjointly with a one-way hash function GOST R 34.11-94 as indicated in [GOSTR341094] and [GOSTR34102001]. This section identifies OIDs for GOST R 34.10-94 and GOST R 34.10-2001 algorithms. The contents of the parameters component for each algorithm may vary and details are provided below for each algorithm separately. 2.2.1 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 one-way, collision free hash function GOST R 34.11-94. This document does not contain GOST R 34.10-94 standard description, which is fully described in [GOSTR341094] in Russian, and brief description in English could be found in [Schneier95] ch. 20.3, p. 495. The ASN.1 OID used to identify GOST R 34.10-94 signature algorithm in fields signatureAlgorithm in Certificate and CertificateList is: id-CryptoPro-algorithms OBJECT IDENTIFIER ::= { iso(1) member-body(2) ru(643) rans(2) cryptopro(2) } id-GostR3411-94-with-GostR3410-94 OBJECT IDENTIFIER ::= { id-CryptoPro-algorithms gostR3411-94-with-gostR3410-94(4)} Leontiev & Shefanovski Informational [Page 4] Internet-Draft Using GOST with PKIX February 2005 GostR3410-94-CertificateSignatureAlgorithms ALGORITHM-IDENTIFIER ::= { { NULL IDENTIFIED BY id-GostR3411-94-with-GostR3410-94 } | { GostR3410-94-PublicKeyParameters IDENTIFIED BY id-GostR3411-94-with-GostR3410-94 } } GostR3410-94-PublicKeyParameters are defined in section 2.3.1. When the id-GostR3411-94-with-GostR3410-94 algorithm identifier appears in an AlgorithmIdentifier and parameters are omitted, the parameters from the public key of the signer's certificate MUST be used. If the parameters from the public key of the signer's certificate are also omited, and it's issuer's certificate has the same public key algorithm, parameters from the public key of the issuer's certificate MUST be used, and so on. Signature algorithm GOST R 34.10-94 generates digital signature in the form of a binary 512-bit vector (256||256). That is, the least-significant (1-st) bit of signatureValue BIT STRING contains the least-significant (1-st) bit of , and the most-significant (512th) bit of signatureValue contains the most-significant (256th) bit of . 2.2.2 Signature Algorithm GOST R 34.10-2001 GOST R 34.10-2001 was 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 one-way, collision free hash function GOST R 34.11-94. This document does not contain GOST R 34.10-2001 standard description, which is fully described in [GOSTR34102001]. The ASN.1 OID used to identify GOST R 34.10-2001 signature algorithm in fields signatureAlgorithm of Certificate and CertificateList is: id-GostR3411-94-with-GostR3410-2001 OBJECT IDENTIFIER ::= { id-CryptoPro-algorithms gostR3411-94-with-gostR3410-2001(3) } GostR3410-2001-CertificateSignatureAlgorithms ALGORITHM-IDENTIFIER ::= { { NULL IDENTIFIED BY id-GostR3411-94-with-GostR3410-2001 } | { GostR3410-2001-PublicKeyParameters IDENTIFIED BY id-GostR3411-94-with-GostR3410-2001 } } GostR3410-2001-PublicKeyParameters are defined in section 2.3.2. Leontiev & Shefanovski Informational [Page 5] Internet-Draft Using GOST with PKIX February 2005 When the id-GostR3411-94-with-GostR3410-2001 algorithm identifier appears in an AlgorithmIdentifier and parameters are omitted, the parameters from the public key of the signer's certificate MUST be used. If the parameters from the public key of the signer's certificate are also omited, and it's issuer's certificate has the same public key algorithm, parameters from the public key of the issuer's certificate MUST be used, and so on. Signature algorithm GOST R 34.10-2001 generates digital signature in the form of a binary 512-bit vector (256||256). That is, the least-significant (1-st) bit of signatureValue BIT STRING contains the least-significant (1-st) bit of , and the most-significant (512th) bit of signatureValue contains the most-significant (256th) bit of . 2.3 Subject Public Key Algorithms In according to [RFC3280] the certificates may contain a public key for any algorithm. Within the framework of this specification the only GOST R 34.10-94 and GOST R 34.10-2001 public key algorithms defined. The algorithm and associated parameters are definable as OID in certificate through ASN.1 structure AlgorithmIdentifier. This section identifies defines OID and public key parameters for the GOST R 34.10-94 and GOST R 34.10-2001 algorithms. The appropriate CA MUST use the predefined OID issuing certificates containing public keys for these algorithms. The appropriate applications supporting any of these algorithms MUST fully recognize the OID identified in this section 2.3.1 GOST R 34.10-94 Keys This section defines OID and parameter encoding for inclusion of GOST R 34.10-94 public key in certificate. Such public key can be used for digital signature validation algorithm GOST R 34.10-94 [GOSTR341094], and for key derivation algorithm VKO GOST R 34.10-94 [CPALGS]. An assumed cryptographic key usage MAY be specified by keyUsage extension [RFC3280]. The usage of the same key for signature and key derivation is NOT RECOMMENDED, but possible. Public key OID for GOST R 34.10-94 declared in this document is: id-GostR3410-94 OBJECT IDENTIFIER ::= { id-CryptoPro-algorithms gostR3410-94(20) } SubjectPublicKeyInfo.algorithm.algorithm field (see [RFC3280]) for Leontiev & Shefanovski Informational [Page 6] Internet-Draft Using GOST with PKIX February 2005 GOST R 34.10-94 keys MUST be id-GostR3410-94; SubjectPublicKeyInfo.algorithm.parameters in this case MUST have the following structure: GostR3410-94-PublicKeyParameters ::= SEQUENCE { publicKeyParamSet OBJECT IDENTIFIER, digestParamSet OBJECT IDENTIFIER, encryptionParamSet OBJECT IDENTIFIER OPTIONAL } where: * publicKeyParamSet - public key parameters identifier for GOST R 34.10-94 (see section 8.3 of [CPALGS]) * digestParamSet - parameters identifier for GOST R 34.11-94 (see section 8.2 of [CPALGS]) * encryptionParamSet - optional parameters identifier for GOST 28147-89 (see section 8.1 of [CPALGS]) MAY be present in any certificate and MUST be present if keyUsage includes keyAgreement or keyEnchiperment. If GOST R 34.10-94 algorithm parameters are omitted in subjectPublicKeyInfo, and CA signs subject certificate using GOST R 34.10-94, then GOST R 34.10-94 parameters taken from subjectPublicKeyInfo field of issuer certificate are applicable to public key of GOST R 34.10-94 subject. That is, cryptographic parameters inheritance takes place. If subjectPublicKeyInfo AlgorithmIdentifier field contain no parameters, but CA sign certificate using signature algorithm different from GOST R 34.10-94, such certificate MUST be rejected by conforming applications. Public key GOST R 34.10-94 MUST be ASN.1 encoded in following way. In GOST R 34.10-94 public key is a number y = a^x (mod p), where a and p - parameters, and y is a bit-vector (1024), at that encoding should present 1024 (BIT STRING) as a vector holding data in a little-endian. At first, a key is presented as an OCTET STRING, and then, being DER-encoded, presented as a BIT STRING. GostR3410-94-PublicKey ::= BIT STRING GostR3410-94-PublicKeyOctetString ::= OCTET STRING If the keyUsage extension is present in an end-entity certificate, Leontiev & Shefanovski Informational [Page 7] Internet-Draft Using GOST with PKIX February 2005 which contains a GOST R 34.10-94 public key, the following values MAY be present: digitalSignature; nonRepudiation. keyEncipherment; keyAgreement. If the keyAgreement or keyEnchiperment extension is present in a certificate GOST R 34.10-94 public key, the following values MAY be present as well: encipherOnly; decipherOnly. The keyUsage extension MUST NOT assert both encipherOnly and decipherOnly. If the keyUsage extension is present in an CA or CRL signer certificate which contain a GOST R 34.10-94 public key, the following values MAY be present: digitalSignature; nonRepudiation; keyCertSign; cRLSign. 2.3.2 GOST R 34.10-2001 Keys This section defines OID and parameter encoding for inclusion of GOST R 34.10-2001 public key in certificate. Such public key can be used for digital signature validation algorithm GOST R 34.10-2001 [GOSTR34102001], and for key derivation algorithm VKO GOST R 34.10-2001 [CPALGS]. An assumed cryptographic key usage MAY be specified by keyUsage extension [RFC3280]. The usage of the same key for signature and key derivation is NOT RECOMMENDED, but possible. Public key OID for GOST R 34.10-2001 declared in this document is: id-GostR3410-2001 OBJECT IDENTIFIER ::= { id-CryptoPro-algorithms gostR3410-2001(19) } SubjectPublicKeyInfo.algorithm.algorithm field (see [RFC3280]) for GOST R 34.10-2001 keys MUST be id-GostR3410-2001; SubjectPublicKeyInfo.algorithm.parameters in this case MUST have the Leontiev & Shefanovski Informational [Page 8] Internet-Draft Using GOST with PKIX February 2005 following structure: GostR3410-2001-PublicKeyParameters ::= SEQUENCE { publicKeyParamSet OBJECT IDENTIFIER, digestParamSet OBJECT IDENTIFIER, encryptionParamSet OBJECT IDENTIFIER OPTIONAL } where: * publicKeyParamSet - public key parameters identifier for GOST R 34.10-2001 (see section 8.4 of [CPALGS]) * digestParamSet - parameters identifier for GOST R 34.11-94 (see section 8.2 of [CPALGS]) * encryptionParamSet - optional parameters identifier for GOST 28147-89 (see section 8.1 of [CPALGS]) MAY be present in any certificate and MUST be present if keyUsage includes keyAgreement or keyEnchiperment. If GOST R 34.10-2001 algorithm parameters are omitted in subjectPublicKeyInfo, and CA signs subject certificate using GOST R 34.10-2001, then GOST R 34.10-2001 parameters taken from subjectPublicKeyInfo field of issuer certificate are applicable to public key of GOST R 34.10-2001 subject. That is, cryptographic parameters inheritance takes place. If subjectPublicKeyInfo AlgorithmIdentifier field contain no parameters, but CA sign certificate using signature algorithm different from GOST R 34.10-2001, such certificate MUST be rejected by conforming applications. GOST R 34.10-2001 public key MUST be ASN.1 encoded in a following way. GOST R 34.10-2001 specifies that public key is a point on the elliptic curve Q = dP, where d is a private key, P is a base point, and Q presents in a way of 512-bit vector (256||256). This vector is DER-encoded as two data blocks. At first, 256 block, then 256 block. subjectPublicKey field BIT STRING type is presented as a taken up object GostR3410-2001-PublicKeyOctetString. At that, least-significant of the first octet (GostR3410-2001-PublicKeyOctetString[0]) corresponds to least- significant (1-st) of vector 256||256 (Yq1 = (GostR3410-2001-PublicKeyOctetString[0] & 1)). Whereas most-significant of 64-th octet (GostR3410-2001-PublicKeyOctetString[63]) corresponds to most- Leontiev & Shefanovski Informational [Page 9] Internet-Draft Using GOST with PKIX February 2005 significant (512-d) of vector 256||256 (Xq256 = ((GostR3410-2001-PublicKeyOctetString[63] & 0x80)>>7)). In other words, 256||256 vector is stored in little-endian, that correspond binary vector form and their concatenation in GOST R 34.10-2001 ch. 5.3. At first, key is placed in OCTET STRING, than is DER-encoded and placed in BIT STRING. GostR3410-2001-PublicKey ::= BIT STRING GostR3410-2001-PublicKeyOctetString ::= OCTET STRING If the keyUsage extension is present in an end-entity certificate, which conveys a GOST R 34.10-2001 public key, the following values MAY be present: digitalSignature, nonRepudiation, keyEncipherment, keyAgreement. If the keyAgreement or keyEnchiperment extension is present in a certificate, the following values MAY be present: encipherOnly, decipherOnly. The keyUsage extension MUST NOT assert both encipherOnly and decipherOnly. If the keyUsage extension is present in an CA or CRL signer certificate which contain a GOST R 34.10-2001 public key, the following values MAY be present: digitalSignature, nonRepudiation, keyCertSign, cRLSign. 3 Security Considerations It is RECCOMENDED, that applications verify signature values and subject public keys to conform to [GOSTR34102001], [GOSTR341094] standards prior to their use. When certificate is used as analogue to a manual signing, in the context of Russian Federal Digital Signature Law [RFDSL], certificate MUST contain keyUsage extension, it MUST be critical, and keyUsage Leontiev & Shefanovski Informational [Page 10] Internet-Draft Using GOST with PKIX February 2005 MUST NOT include keyEncipherment and keyAgreement. When certificate validity period (typicaly 5 years for end entities and 7 years for CAs in Russia) is not equal to the private key validity period (typicaly 15 months in Russia) it is RECOMENDED to use private key usage period extension.
