Introduction 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]. This document supplements RFC 3279 [PKALGS]. It describes the conventions for using the GOST R 34.10-94 and GOST R 34.10-2001 signature algorithms, VKO GOST R 34.10-94 and VKO GOST R 34.10-2001 key derivation algorithms, and GOST R 34.11-94 one-way hash function in the Internet X.509 Public Key Infrastructure (PKI) [PROFILE]. This document provides supplemental information and specifications needed by the "Russian Cryptographic Software Compatibility Agreement" community. The algorithm identifiers and associated parameters for subject public keys that employ the GOST R 34.10-94 [GOSTR341094] / VKO GOST R 34.10-94 [CPALGS] or the GOST R 34.10-2001 [GOSTR341001] / VKO GOST R 34.10-2001 [CPALGS] algorithms, and the encoding format for the signatures produced by these algorithms are specified. Also, the algorithm identifiers for using the GOST R 34.11-94 one-way hash function with the GOST R 34.10-94 and GOST R 34.10-2001 signature algorithms are specified. Leontiev & Shefanovski Standards Track [Page 2] Internet-Draft Using GOST with PKIX January 2006 This specification defines the contents of the signatureAlgorithm, signatureValue, signature, and subjectPublicKeyInfo fields within X.509 Certificates and CRLs. For each algorithm, the appropriate alternatives for the keyUsage certificate extension are provided. 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 [PROFILE]. 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. CAs and/or applications conforming to this standard MUST support at least one of the specified public key and signature algorithms. 2.1. One-way Hash Function This section describes the use of a 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 RFC 3280 [PROFILE]. 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 and Research Institute of Standardization". The algorithm GOST R 34.11-94 produces a 256-bit hash value of an arbitrary finite bit length input. This document does not contain the full GOST R 34.11-94 specification, which can be found in [GOSTR3411] (in Russian). [Schneier95] ch. 18.11, p. 454. contains a brief technical description in English. This function MUST always be used with parameter set identified by id-GostR3411-94-CryptoProParamSet (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. These signature algorithms MUST always be used with a one-way hash Leontiev & Shefanovski Standards Track [Page 3] Internet-Draft Using GOST with PKIX January 2006 function GOST R 34.11-94 as indicated in [GOSTR341094] and [GOSTR341001]. This section defines algorithm identifiers and parameters to be used in the signatureAlgorithm field in a Certificate or CertificateList. 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 document does not contain the full GOST R 34.10-94 specification, which can be found in [GOSTR341094] (in Russian). [Schneier95] ch. 20.3, p. 495 contains a brief technical description in English. The ASN.1 object identifier used to identify this signature algorithm is: id-GostR3411-94-with-GostR3410-94 OBJECT IDENTIFIER ::= { iso(1) member-body(2) ru(643) rans(2) cryptopro(2) gostR3411-94-with-gostR3410-94(4) } When the id-GostR3411-94-with-GostR3410-94 algorithm identifier appears as the algorithm field in an AlgorithmIdentifier, the encoding SHALL omit the parameters field. That is, the AlgorithmIdentifier SHALL be a SEQUENCE of one component: the OBJECT IDENTIFIER id-GostR3411-94-with-GostR3410-94. 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 first 32 octets contain the big endian representation of s and second 32 octets contain the big endian representation of r'. This definition of a signature value is directly usable in CMS [CMS], where such values are represented as octet strings. However, signature values in certificates and CRLs [PROFILE] are represented as bit strings, and thus the octet string representation must be converted. To convert an octet string signature value to a bit string, the most significant bit of the first octet of the signature value SHALL become the first bit of the bit string, and so on through the least significant bit of the last octet of the signature value, which SHALL become the last bit of the bit string. 2.2.2. Signature Algorithm GOST R 34.10-2001 Leontiev & Shefanovski Standards Track [Page 4] Internet-Draft Using GOST with PKIX January 2006 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 document does not contain the full GOST R 34.10-2001 specification, which can be found in [GOSTR341001] (in Russian). The ASN.1 object identifier used to identify this signature algorithm is: id-GostR3411-94-with-GostR3410-2001 OBJECT IDENTIFIER ::= { iso(1) member-body(2) ru(643) rans(2) cryptopro(2) gostR3411-94-with-gostR3410-2001(3) } When the id-GostR3411-94-with-GostR3410-2001 algorithm identifier appears as the algorithm field in an AlgorithmIdentifier, the encoding SHALL omit the parameters field. That is, the AlgorithmIdentifier SHALL be a SEQUENCE of one component: the OBJECT IDENTIFIER id-GostR3411-94-with-GostR3410-2001. 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 first 32 octets contain the big endian representation of s and second 32 octets contain the big endian representation of r'. The process decribed above (Section 2.2.10) MUST be used to convert this octet string representation to a bit string for use in certificates and CRLs. 2.3. Subject Public Key Algorithms This section defines OIDs and public key parameters for public keys that employ the GOST R 34.10-94 [GOSTR341094] / VKO GOST R 34.10-94 [CPALGS] or the GOST R 34.10-2001 [GOSTR341001] / VKO GOST R 34.10-2001 [CPALGS] algorithms. Use of the same key for both signature and key derivation is NOT RECOMMENDED. The intended application for the key MAY be indicated in the keyUsage certificate extension (see [PROFILE], Section 4.2.1.3). 2.3.1. GOST R 34.10-94 Keys GOST R 34.10-94 public keys can be used for signature algorithm GOST R 34.10-94 [GOSTR341094] and for key derivation algorithm VKO GOST R 34.10-94 [CPALGS]. GOST R 34.10-94 public keys are identified by the following OID: Leontiev & Shefanovski Standards Track [Page 5] Internet-Draft Using GOST with PKIX January 2006 id-GostR3410-94 OBJECT IDENTIFIER ::= { iso(1) member-body(2) ru(643) rans(2) cryptopro(2) gostR3410-94(20) } The SubjectPublicKeyInfo.algorithm.algorithm field (see RFC 3280 [PROFILE]) for GOST R 34.10-94 keys MUST be set to id-GostR3410-94. When the id-GostR3410-94 algorithm identifier appears as the algorithm field in an AlgorithmIdentifier, the encoding MAY omit the parameters field or set it to NULL. Otherwise this field MUST have the following structure: GostR3410-94-PublicKeyParameters ::= SEQUENCE { publicKeyParamSet OBJECT IDENTIFIER, digestParamSet OBJECT IDENTIFIER, encryptionParamSet OBJECT IDENTIFIER DEFAULT id-Gost28147-89-CryptoPro-A-ParamSet } 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 - parameters identifier for GOST 28147-89 (see section 8.1 of [CPALGS]) Absence of parameters SHALL be processed as described in RFC 3280 [PROFILE], section 6.1, that is, parameters are inherited from the issuer certificate. When the working_public_key_parameters variable is set to null, any signature SHALL be rejected. The GOST R 34.10-94 public key MUST be ASN.1 DER encoded as an OCTET STRING; this encoding shall be used as the contents (i.e., the value) of the subjectPublicKey component (a BIT STRING) of the SubjectPublicKeyInfo data element. GostR3410-94-PublicKey ::= OCTET STRING -- public key, Y GostR3410-94-PublicKey MUST contain 128 octets of the little-endian representation of the public key Y = a^x (mod p), where a and p are public key parameters, and x is a private key. If the keyUsage extension is present in an end-entity certificate Leontiev & Shefanovski Standards Track [Page 6] Internet-Draft Using GOST with PKIX January 2006 that contains a GOST R 34.10-94 public key, the following values MAY be present: digitalSignature; nonRepudiation; keyEncipherment; and 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; and 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 contains a GOST R 34.10-94 public key, the following values MAY be present: digitalSignature; nonRepudiation; keyCertSign; and cRLSign. 2.3.2. GOST R 34.10-2001 Keys GOST R 34.10-2001 public keys can be used for signature algorithm GOST R 34.10-2001 [GOSTR341001] and for key derivation algorithm VKO GOST R 34.10-2001 [CPALGS]. GOST R 34.10-2001 public keys are identified by the following OID: id-GostR3410-2001 OBJECT IDENTIFIER ::= { iso(1) member-body(2) ru(643) rans(2) cryptopro(2) gostR3410-2001(19) } The SubjectPublicKeyInfo.algorithm.algorithm field (see RFC 3280 [PROFILE]) for GOST R 34.10-2001 keys MUST be set to id- GostR3410-2001. When the id-GostR3410-2001 algorithm identifier appears as the algorithm field in an AlgorithmIdentifier, the encoding MAY omit the parameters field or set it to NULL. Otherwise this field MUST have the following structure: Leontiev & Shefanovski Standards Track [Page 7] Internet-Draft Using GOST with PKIX January 2006 GostR3410-2001-PublicKeyParameters ::= SEQUENCE { publicKeyParamSet OBJECT IDENTIFIER, digestParamSet OBJECT IDENTIFIER, encryptionParamSet OBJECT IDENTIFIER DEFAULT id-Gost28147-89-CryptoPro-A-ParamSet } 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 - parameters identifier for GOST 28147-89 (see section 8.1 of [CPALGS]) Absence of parameters SHALL be processed as described in RFC 3280 [PROFILE], section 6.1, that is, parameters are inherited from the issuer certificate. When the working_public_key_parameters variable is set to null, any signature SHALL be rejected. The GOST R 34.10-2001 public key MUST be ASN.1 DER encoded as an OCTET STRING; this encoding shall be used as the contents (i.e., the value) of the subjectPublicKey component (a BIT STRING) of the SubjectPublicKeyInfo data element. GostR3410-2001-PublicKey ::= OCTET STRING -- public key vector, Q According to [GOSTR341001], a public key is a point on the elliptic curve Q = (x,y). GostR3410-2001-PublicKey MUST contain 64 octets, where first 32 octets contain little endian representation of x and second 32 octets contain little endian representation of y. This corresponds to the binary representation of (256||256) from [GOSTR341001], ch. 5.3. The same keyUsage constraints apply for use of GOST R 34.10-2001 keys as described in Section 2.3.1 for GOST R 34.10-94 keys. 3. Security Considerations It is RECOMMENDED, that applications verify signature values and subject public keys to conform to [GOSTR341001] [GOSTR341094] standards prior to their use. Leontiev & Shefanovski Standards Track [Page 8] Internet-Draft Using GOST with PKIX January 2006 When a certificate is used to support digital signatures as an analogue to manual ("wet") signatures, in the context of Russian Federal Digital Signature Law [RFDSL], the certificate MUST contain keyUsage extension, it MUST be critical, and keyUsage MUST NOT include keyEncipherment and keyAgreement. It is RECOMMENDED, that CAs and applications make sure that the private key is not used for more than it's allowed validity period (typically 15 months for both GOST R 34.10-94 and GOST R 34.10-2001 algorithms).
