Introduction + + This specification is one part of a family of standards for the X.509 + Public Key Infrastructure (PKI) for the Internet. It is based on + [X.509] and [RFC 3280], which defines underlying certificate formats + and semantics needed for a full implementation of this standard. + + This profile includes specific mechanisms intended for use with + Qualified Certificates. The term Qualified Certificates and the + assumptions that affect the scope of this document are discussed in + Section 2. + + + +Santesson, et al. Standards Track [Page 2] + +RFC 3739 Qualified Certificates Profile March 2004 + + + Section 3 defines requirements on certificate information content. + This specification provides profiles for two certificate fields: + issuer and subject. It also provides profiles for four certificate + extensions defined in RFC 3280: subject alternate name, subject + directory attributes, certificate policies, and key usage, and it + defines two additional extensions: biometric information and + qualified certificate statements. The certificate extensions are + presented in the 1997 Abstract Syntax Notation One (ASN.1) [X.680], + but in conformance with RFC 3280 the 1988 ASN.1 module in Appendix A + contains all normative definitions (the 1997 module in Appendix A is + informative). + + In Section 4, some security considerations are discussed in order to + clarify the security context in which the standard may be utilized. + + Appendix A contains all relevant ASN.1 structures that are not + already defined in RFC 3280. Appendix B contains a note on + attributes. Appendix C contains an example certificate. + + The appendices sections are followed by the References, Authors + Addresses, and the Full Copyright Statement. + +1.1. Changes since RFC 3039 + + This specification obsoletes RFC 3039. This specification differs + from RFC 3039 in the following basic areas: + + * Some editorial clarifications have been made to introductory + sections to clarify that this profile is generally applicable + to a broad type of certificates, even if its prime purpose is + to facilitate issuance of Qualified Certificates. + + * To align with RFC 3280, support for domainComponent and title + attributes in subject names are included, and postalAddress is + no longer supported. + + * To align with actual usage, support for the title attribute in + the subject directory attributes extension is no longer + supported. + + * To better facilitate broad applicability of this profile, some + constraints on key usage settings in the key usage extension + have been removed. + + * A new qc-Statement reflecting this second version of the + profile has been defined in Section 3.2.6.1. This profile + obsoletes RFC 3039, but the qc-statement reflecting compliance + with RFC 3039 is also defined for backwards compatibility. + + + +Santesson, et al. Standards Track [Page 3] + +RFC 3739 Qualified Certificates Profile March 2004 + + +1.2. Definitions + + 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 BCP 14, [RFC 2119]. + +2. Requirements and Assumptions + + The term "Qualified Certificate" is used by the European Directive on + Electronic Signature [EU-ESDIR] to refer to a specific type of + certificates, with appliance in European electronic signature + legislation. This specification is intended to support this class of + certificates, but its scope is not limited to this application. + + Within this standard, the term "Qualified Certificate" is used + generally, describing a certificate whose primary purpose is to + identify a person with a high level of assurance, where the + certificate meets some qualification requirements defined by an + applicable legal framework, such as the European Directive on + Electronic Signature [EU-ESDIR]. The actual mechanisms that decide + whether a certificate should or should not be considered a "Qualified + Certificate" in regard to any legislation are outside the scope of + this standard. + + Harmonization in the field of identity certificates issued to natural + persons, in particular Qualified Certificates, is essential within + several aspects that fall outside the scope of RFC 3280. The most + important aspects that affect the scope of this specification are: + + - Definition of names and identity information in order to identify + the associated subject in a uniform way. + + - Definition of information which identifies the CA and the + jurisdiction under which the CA operates when issuing a particular + certificate. + + - Definition of key usage extension usage for Qualified + Certificates. + + - Definition of information structure for storage of biometric + information. + + - Definition of a standardized way to store predefined statements + with relevance for Qualified Certificates. + + - Requirements for critical extensions. + + + + + +Santesson, et al. Standards Track [Page 4] + +RFC 3739 Qualified Certificates Profile March 2004 + + +2.1. Properties + + This profile accommodates profiling needs for Qualified Certificates + based on the assumptions that: + + - Qualified Certificates are issued by a CA that makes a statement + that the certificate serves the purpose of a Qualified + Certificate, as discussed in Section 2.2. + + - The Qualified Certificate indicates a certificate policy + consistent with liabilities, practices, and procedures undertaken + by the CA, as discussed in Section 2.3. + + - The Qualified Certificate is issued to a natural person (living + human being). + + - The Qualified Certificate contains a name which may be either + based on the real name of the subject or a pseudonym. + +2.2. Statement of Purpose + + This profile defines conventions to declare within a certificate that + it serves the purpose of being a Qualified Certificate. This enables + the CA to explicitly define this intent. + + The function of this declaration is thus to assist any concerned + entity in evaluating the risk associated with creating or accepting + signatures that are based on a Qualified Certificate. + + This profile defines two ways to include this information: + + - As information defined by a certificate policy included in the + certificate policies extension, and + + - As a statement included in the Qualified Certificates Statements + extension. + +2.3. Policy Issues + + Certain policy aspects define the context in which this profile is to + be understood and used. It is however outside the scope of this + profile to specify any policies or legal aspects that will govern + services that issue or utilize certificates according to this + profile. + + It is however an underlying assumption in this profile that a + responsible issuing CA will undertake to follow a certificate policy + that is consistent with its liabilities, practices, and procedures. + + + +Santesson, et al. Standards Track [Page 5] + +RFC 3739 Qualified Certificates Profile March 2004 + + +2.4. Uniqueness of names + + Distinguished name is originally defined in X.501 [X.501] as a + representation of a directory name, defined as a construct that + identifies a particular object from among a set of all objects. The + distinguished name MUST be unique for each subject entity certified + by the one CA as defined by the issuer name field, for the whole life + time of the CA. + +3. Certificate and Certificate Extensions Profile + + This section defines certificate profiling conventions. The profile + is based on the Internet certificate profile RFC 3280, which in turn + is based on the X.509 version 3 format. For full implementation of + this section, implementers are REQUIRED to consult the underlying + formats and semantics defined in RFC 3280. + + ASN.1 definitions, relevant for this section that are not supplied by + RFC 3280, are supplied in Appendix A. + +3.1. Basic Certificate Fields + + This section provides additional details regarding the contents of + two fields in the basic certificate. These fields are the issuer and + subject fields. + +3.1.1. Issuer + + The issuer field SHALL identify the organization responsible for + issuing the certificate. The name SHOULD be an officially registered + name of the organization. + + The distinguished name of the issuer SHALL be specified using an + appropriate subset of the following attributes: + + domainComponent; + countryName; + stateOrProvinceName; + organizationName; + localityName; and + serialNumber. + + The domainComponent attribute is defined in [RFC 2247], all other + attributes are defined in [RFC 3280] and [X.520]. + + Additional attributes MAY be present, but they SHOULD NOT be + necessary to identify the issuing organization. + + + + +Santesson, et al. Standards Track [Page 6] + +RFC 3739 Qualified Certificates Profile March 2004 + + + A relying party MAY have to consult associated certificate policies + and/or the issuer's CPS, in order to determine the semantics of name + fields. + +3.1.2. Subject + + The subject field of a certificate compliant with this profile SHALL + contain a distinguished name of the subject (see 2.4 for definition + of distinguished name). + + The subject field SHALL contain an appropriate subset of the + following attributes: + + domainComponent; + countryName; + commonName; + surname; + givenName; + pseudonym; + serialNumber; + title; + organizationName; + organizationalUnitName; + stateOrProvinceName; and + localityName. + + The domainComponent attribute is defined in [RFC 2247], all other + attributes are defined in [RFC 3280] and [X.520]. + + Other attributes MAY also be present; however, the use of other + attributes MUST NOT be necessary to distinguish one subject name from + another subject name. That is, the attributes listed above are + sufficient to ensure unique subject names. + + Of these attributes, the subject field SHALL include at least one of + the following: + + Choice I: commonName + Choice II: givenName + Choice III: pseudonym + + The countryName attribute value specifies a general context in + which other attributes are to be understood. The country + attribute does not necessarily indicate the subject's country of + citizenship or country of residence, nor does it have to indicate + the country of issuance. + + + + + +Santesson, et al. Standards Track [Page 7] + +RFC 3739 Qualified Certificates Profile March 2004 + + + Note: Many X.500 implementations require the presence of countryName + in the DIT. In cases where the subject name, as specified in the + subject field, specifies a public X.500 directory entry, the + countryName attribute SHOULD always be present. + + The commonName attribute value SHALL, when present, contain a name + of the subject. This MAY be in the subject's preferred + presentation format, or a format preferred by the CA, or some + other format. Pseudonyms, nicknames, and names with spelling + other than defined by the registered name MAY be used. To + understand the nature of the name presented in commonName, + complying applications MAY have to examine present values of the + givenName and surname attributes, or the pseudonym attribute. + + Note: Many client implementations presuppose the presence of the + commonName attribute value in the subject field and use this value to + display the subject's name regardless of present givenName, surname, + or pseudonym attribute values. + + The surname and givenName attribute types SHALL be used in the + subject field if neither the commonName attribute nor the + pseudonym attribute is present. In cases where the subject only + has a givenName, the surname attribute SHALL be omitted. + + The pseudonym attribute type SHALL, if present, contain a + pseudonym of the subject. Use of the pseudonym attribute MUST NOT + be combined with use of any of the attributes surname and/or + givenName. + + The serialNumber attribute type SHALL, when present, be used to + differentiate between names where the subject field would + otherwise be identical. This attribute has no defined semantics + beyond ensuring uniqueness of subject names. It MAY contain a + number or code assigned by the CA or an identifier assigned by a + government or civil authority. It is the CA's responsibility to + ensure that the serialNumber is sufficient to resolve any subject + name collisions. + + The title attribute type SHALL, when present, be used to store a + designated position or function of the subject within the + organization specified by present organizational attributes in the + subject field. The association between the title, the subject, + and the organization is beyond the scope of this document. + + The organizationName and the organizationalUnitName attribute + types SHALL, when present, be used to store the name and relevant + information of an organization with which the subject is + + + + +Santesson, et al. Standards Track [Page 8] + +RFC 3739 Qualified Certificates Profile March 2004 + + + associated. The type of association between the organization and + the subject is beyond the scope of this document. + + The stateOrProvinceName and the localityName attribute types + SHALL, when present, be used to store geographical information + with which the subject is associated. If an organizationName + value is also present, then the stateOrProvinceName and + localityName attribute values SHALL be associated with the + specified organization. The type of association between the + stateOrProvinceName and the localityName and either the subject or + the organizationName is beyond the scope of this document. + + Compliant implementations SHALL be able to interpret the attributes + named in this section. + +3.2. Certificate Extensions + + This section provides additional details regarding the contents of + four certificate extensions defined in RFC 3280: Subject Alternative + Name, Subject directory attributes, Certificate policies, and Key + usage. This section also defines two additional extensions: + biometric information and qualified certificate statements. + +3.2.1. Subject Alternative Name + + If the subjectAltName extension is present, and it contains a + directoryName name, then the directoryName MUST follow the + conventions specified in section 3.1.2 of this profile. + +3.2.2. Subject Directory Attributes + + The subjectDirectoryAttributes extension MAY be present and MAY + contain additional attributes associated with the subject, as a + complement to present information in the subject field and the + subject alternative name extension. + + Attributes suitable for storage in this extension are attributes + which are not part of the subject's distinguished name, but which MAY + still be useful for other purposes (e.g., authorization). + + This extension MUST NOT be marked critical. + + Compliant implementations SHALL be able to interpret the following + attributes: + + dateOfBirth; + placeOfBirth; + gender; + + + +Santesson, et al. Standards Track [Page 9] + +RFC 3739 Qualified Certificates Profile March 2004 + + + countryOfCitizenship; and + countryOfResidence. + + Other attributes MAY be included according to local definitions. + + The dateOfBirth attribute SHALL, when present, contain the value + of the date of birth of the subject. The manner in which the date + of birth is associated with the subject is outside the scope of + this document. The date of birth is defined in the + GeneralizedTime format and SHOULD specify GMT 12.00.00 (noon) down + to the granularity of seconds, in order to prevent accidental + change of date due to time zone adjustments. For example, a birth + date of September 27, 1959 is encoded as "19590927120000Z". + Compliant certificate parsing applications SHOULD ignore any time + data and just present the contained date without any time zone + adjustments. + + The placeOfBirth attribute SHALL, when present, contain the value + of the place of birth of the subject. The manner in which the + place of birth is associated with the subject is outside the scope + of this document. + + The gender attribute SHALL, when present, contain the value of the + gender of the subject. For females the value "F" (or "f"), and + for males the value "M" (or "m"), have to be used. The manner in + which the gender is associated with the subject is outside the + scope of this document. + + The countryOfCitizenship attribute SHALL, when present, contain + the identifier of at least one of the subject's claimed countries + of citizenship at the time the certificate was issued. If more + than one country of citizenship is specified, each country of + citizenship SHOULD be specified through a separate, single-valued + countryOfCitizenship attribute. Determination of citizenship is a + matter of law and is outside the scope of this document. + + The countryOfResidence attribute SHALL, when present, contain the + value of at least one country in which the subject is resident. + If more than one country of residence is specified, each country + of residence SHOULD be specified through a separate, single-valued + countryOfResidence attribute. Determination of residence is a + matter of law and is outside the scope of this document. + + + + + + + + + +Santesson, et al. Standards Track [Page 10] + +RFC 3739 Qualified Certificates Profile March 2004 + + +3.2.3. Certificate Policies + + The certificate policies extension SHALL be present and SHALL contain + the identifier of at least one certificate policy which reflects the + practices and procedures undertaken by the CA. The certificate + policy extension MAY be marked critical. + + Information provided by the issuer stating the purpose of the + certificate, as discussed in Section 2.2, SHOULD be evident through + indicated policies. + + The certificate policies extension MUST include all policy + information needed for certification path validation. If policy + related statements are included in the QCStatements extension (see + 3.2.6), then these statements SHOULD also be contained in the + identified policies. + + Certificate policies MAY be combined with any qualifier defined in + RFC 3280. + +3.2.4. Key Usage + + The key usage extension SHALL be present. Key usage settings SHALL + be set in accordance with RFC 3280 definitions. Further requirements + on key usage settings MAY be defined by local policy and/or local + legal requirements. + + The key usage extension SHOULD be marked critical. + +3.2.5. Biometric Information + + This section defines an OPTIONAL extension for storage of biometric + information. Biometric information is stored in the form of a hash + of a biometric template. + + The purpose of this extension is to provide a means for the + authentication of biometric information. The biometric information + that corresponds to the stored hash is not stored in this extension, + but the extension MAY include a URI (sourceDataUri) that references a + file containing this information. + + If included, the URI MUST use the HTTP scheme (http://) [HTTP/1.1] or + the HTTPS scheme (https://) [RFC 2818]. Since the fact that + identifying data is being checked may itself be sensitive + information, those deploying this mechanism may also wish to consider + using URIs which cannot be easily tied by outsiders to the identities + of those whose information is being retrieved. + + + + +Santesson, et al. Standards Track [Page 11] + +RFC 3739 Qualified Certificates Profile March 2004 + + + Use of the URI option presumes that the data encoding format of the + file content is determined through means outside the scope of this + specification, such as file naming conventions and metadata inside + the file. Use of this URI option does not imply that it is the only + way to access this information. + + It is RECOMMENDED that biometric information in this extension be + limited to information types suitable for human verification, i.e., + where the decision of whether the information is an accurate + representation of the subject is naturally performed by a person. + This implies a usage where the biometric information is represented + by, for example, a graphical image displayed to the relying party, + which MAY be used by the relying party to enhance identification of + the subject. + + This extension MUST NOT be marked critical. + + biometricInfo EXTENSION ::= { + SYNTAX BiometricSyntax + IDENTIFIED BY id-pe-biometricInfo } + + id-pe-biometricInfo OBJECT IDENTIFIER ::= {id-pe 2} + + BiometricSyntax ::= SEQUENCE OF BiometricData + + BiometricData ::= SEQUENCE { + typeOfBiometricData TypeOfBiometricData, + hashAlgorithm AlgorithmIdentifier, + biometricDataHash OCTET STRING, + sourceDataUri IA5String OPTIONAL } + + TypeOfBiometricData ::= CHOICE { + predefinedBiometricType PredefinedBiometricType, + biometricDataID OBJECT IDENTIFIER } + + PredefinedBiometricType ::= INTEGER { picture(0), + handwritten-signature(1)} (picture|handwritten-signature,...) + + The predefined biometric type picture, when present, SHALL identify + that the source picture is in the form of a displayable graphical + image of the subject. The hash of the graphical image SHALL be + calculated over the whole referenced image file. + + The predefined biometric type handwritten-signature, when present, + SHALL identify that the source data is in the form of a displayable + graphical image of the subject's handwritten signature. The hash of + the graphical image SHALL be calculated over the whole referenced + image file. + + + +Santesson, et al. Standards Track [Page 12] + +RFC 3739 Qualified Certificates Profile March 2004 + + +3.2.6. Qualified Certificate Statements + + This section defines an OPTIONAL extension for the inclusion of + statements defining explicit properties of the certificate. + + Each statement SHALL include an object identifier for the statement + and MAY also include optional qualifying data contained in the + statementInfo parameter. + + If the statementInfo parameter is included, then the object + identifier of the statement SHALL define the syntax and SHOULD define + the semantics of this parameter. If the object identifier does not + define the semantics, a relying party may have to consult a relevant + certificate policy or CPS to determine the exact semantics. + + This extension may be critical or non-critical. If the extension is + critical, this means that all statements included in the extension + are regarded as critical. + + qcStatements EXTENSION ::= { + SYNTAX QCStatements + IDENTIFIED BY id-pe-qcStatements } + + -- NOTE: This extension does not allow to mix critical and + -- non-critical Qualified Certificate Statements. Either all + -- statements must be critical or all statements must be + -- non-critical. + + id-pe-qcStatements OBJECT IDENTIFIER ::= { id-pe 3 } + + QCStatements ::= SEQUENCE OF QCStatement + QCStatement ::= SEQUENCE { + statementId QC-STATEMENT.&Id({SupportedStatements}), + statementInfo QC-STATEMENT.&Type + ({SupportedStatements}{@statementId}) OPTIONAL } + + SupportedStatements QC-STATEMENT ::= { qcStatement-1,...} + + A statement suitable for inclusion in this extension MAY be a + statement by the issuer that the certificate is issued as a Qualified + Certificate in accordance with a particular legal system (as + discussed in Section 2.2). + + Other statements suitable for inclusion in this extension MAY be + statements related to the applicable legal jurisdiction within which + the certificate is issued. As an example, this MAY include a maximum + reliance limit for the certificate indicating restrictions on CA's + liability. + + + +Santesson, et al. Standards Track [Page 13] + +RFC 3739 Qualified Certificates Profile March 2004 + + +3.2.6.1. Predefined Statements + + The certificate statement (id-qcs-pkixQCSyntax-v1), identifies + conformance with requirements defined in the obsoleted RFC 3039 + (Version 1). This statement is thus provided for identification of + old certificates issued in conformance with RFC 3039. This statement + MUST NOT be included in certificates issued in accordance with this + profile. + + This profile includes a new qualified certificate statement + (identified by the OID id-qcs-pkixQCSyntax-v2), identifying + conformance with requirements defined in this profile. This + Qualified Certificate profile is referred to as version 2, while RFC + 3039 is referred to as version 1. + + qcStatement-1 QC-STATEMENT ::= { SYNTAX SemanticsInformation + IDENTIFIED BY id-qcs-pkixQCSyntax-v1 } + -- This statement identifies conformance with requirements + -- defined in RFC 3039 (Version 1). This statement may + -- optionally contain additional semantics information as + -- specified below. + + qcStatement-2 QC-STATEMENT ::= { SYNTAX SemanticsInformation + IDENTIFIED BY id-qcs-pkixQCSyntax-v2 } + -- This statement identifies conformance with requirements + -- defined in this Qualified Certificate profile + -- (Version 2). This statement may optionally contain + -- additional semantics information as specified below. + + SemanticsInformation ::= SEQUENCE { + semanticsIdentifier OBJECT IDENTIFIER OPTIONAL, + nameRegistrationAuthorities NameRegistrationAuthorities + OPTIONAL } + (WITH COMPONENTS {..., semanticsIdentifier PRESENT}| + WITH COMPONENTS {..., nameRegistrationAuthorities PRESENT}) + + NameRegistrationAuthorities ::= SEQUENCE SIZE (1..MAX) OF + GeneralName + + The SementicsInformation component identified by id-qcs- + pkixQCSyntax-v1 MAY contain a semantics identifier and MAY identify + one or more name registration authorities. + + The semanticsIdentifier component, if present, SHALL contain an OID, + defining semantics for attributes and names in basic certificate + fields and certificate extensions. The OID may define semantics for + all, or for a subgroup of all present attributes and/or names. + + + + +Santesson, et al. Standards Track [Page 14] + +RFC 3739 Qualified Certificates Profile March 2004 + + + The NameRegistrationAuthorities component, if present, SHALL contain + a name of one or more name registration authorities, responsible for + registration of attributes or names associated with the subject. The + association between an identified name registration authority and + present attributes MAY be defined by a semantics identifier OID, by a + certificate policy (or CPS), or some other implicit factors. + + If a value of type SemanticsInformation is present in a QCStatement + where the statementID component is set to id-qcs-pkix-QCSyntax-v1 or + id-qcs-pkix-QCSyntax-v2, then at least one of the semanticsIdentifier + or nameRegistrationAuthorities fields must be present, as indicated. + Note that the statementInfo component need not be present in a + QCStatement value even if the statementID component is set to id- + qcs-pkix-QCSyntax-v1 or id-qcs-pkix-QCSyntax-v2. + +4. Security Considerations + + The legal value of a digital signature that is validated with a + Qualified Certificate will be highly dependent upon the policy + governing the use of the associated private key. Both the private + key holder, as well as the relying party, should make sure that the + private key is used only with the consent of the legitimate key + holder. + + Since the public keys are for public use with legal implications for + involved parties, certain conditions should exist before CAs issue + certificates as Qualified Certificates. The associated private keys + must be unique for the subject, and must be maintained under the + subject's sole control. That is, a CA should not issue a qualified + certificate if the means to use the private key is not protected + against unintended usage. This implies that the CA has some + knowledge about the subject's cryptographic module. + + The CA must further verify that the public key contained in the + certificate is legitimately representing the subject. + + CAs should not issue CA certificates with policy mapping extensions + indicating acceptance of another CA's policy unless these conditions + are met. + + Combining the nonRepudiation bit in the keyUsage certificate + extension with other keyUsage bits may have security implications + depending on the context in which the certificate is to be used. + Applications validating electronic signatures based on such + certificates should determine whether the present key usage + combination is appropriate for their use. + + + + + +Santesson, et al. Standards Track [Page 15] + +RFC 3739 Qualified Certificates Profile March 2004 + + + The ability to compare two qualified certificates to determine if + they represent the same physical entity is dependent on the semantics + of the subjects' names. The semantics of a particular attribute may + be different for different issuers. Comparing names without + knowledge of the semantics of names in these particular certificates + may provide misleading results. + + This specification is a profile of RFC 3280.
