Abstract
This document forms a certificate profile for Qualified Certificates,
based on RFC 2459, for use in the Internet. The term Qualified
Certificate is used to describe a certificate with a certain
qualified status within applicable governing law. Further, Qualified
Certificates are issued exclusively to physical persons represented
by a registered unmistakable identity.
The goal of this document is to define a general syntax independent
of local legal requirements. The profile is however designed to allow
further profiling in order to meet specific local needs.
It is important to note that the profile does not define any legal
requirements for Qualified Certificates.
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 RFC 2119.
Please send comments on this document to the ietf-pkix@imc.org
mailing list.

1 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 RFC
2459, which defines underlying certificate formats and semantics
needed for a full implementation of this standard.
The standard profiles the format for a specific type of certificates
named Qualified Certificates. The term Qualified Certificates and the
assumptions that affects the scope of this document are discussed in
Section 2.
Section 3 defines requirements on information content in Qualified
Certificates. This profile addresses two fields in the basic
certificate as well as five certificate extensions. The certificate
fields are the subject and issuer fields. The certificate extensions
are subject directory attributes, certificate policies, key usage, a
private extension for storage of biometric data and a private
extension for storage of statements related to Qualified
Certificates.
In Section 4, some security considerations are discussed in order to
clarify the security context in which Qualified Certificates are
assumed to be utilized. Section 5 contains the references.
Appendix A contains all relevant ASN.1 [X.680] structures that are
not already defined in RFC 2459. Appendix B contains an example
certificate. Appendix C contains Authors Addresses and Appendix D
contains the IETF Copyright Statement.
It should be noted that this specification does not define the
specific semantics of Qualified Certificates, and does not define the
policies that should be used with them. That is, this document
defines what information should go into Qualified Certificates, but
not what that information means. A system that uses Qualified
Certificates must define its own semantics for the information in
Qualified Certificates. It is expected that laws and corporate
policies will make these definitions.
2 Requirements and Assumptions
The term "Qualified Certificate" has been used by the European
Commission to describe a certain type of certificates with specific
relevance for European 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 more
generally, describing the format for a certificate whose primary
purpose is identifying a person with high level of assurance in
public non-repudiation services. The actual mechanisms that will
decide whether a certificate should or should not be considered to be
a "Qualified Certificate" in regard to any legislation are outside
the scope of this standard.
Harmonization in the field of Qualified Certificates is essential
within several aspects that fall outside the scope of RFC 2459. 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.
2.1 Properties
A Qualified Certificate as defined in this standard is assumed to
have the following properties:
- The certificate is issued by a CA that makes a public statement
that the certificate serves the purpose of a Qualified
Certificate, as discussed in Section 2.2
- The certificate indicates a certificate policy consistent with
liabilities, practices and procedures undertaken by the CA, as
discussed in 2.3
- The certificate is issued to a natural person (living human being).
- The certificate contains an unmistakable identity based on a
pseudonym or a real name of the subject.
2.2 Statement of Purpose
For a certificate to serve the purpose of being a Qualified
Certificate, this profile assumes that the CA will have to include in
the certificate a public statement that explicitly defines this
intent.
The function of this statement is thus to assist any concerned entity
in evaluating the risk associated with creating or accepting
signatures that are based on a Qualified Certificate.
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 assumed that the issuing CA will undertake to follow a
publicly available certificate policy that is consistent with its
liabilities, practices and procedures.
2.4 Uniqueness of names
Requirements on name uniqueness are described in this standard
through the terms "distinguished name" and "unmistakable identity",
having the following meaning:
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 the set of all objects. An
object can be assigned a distinguished name without being represented
by an entry in the Directory, but this name is then the name its
object entry could have had if it were represented in the Directory.
In the context of qualified certificates, a distinguished name
denotes a set of attribute values [X.501] which forms a name that is
unambiguous within a certain domain that forms either a real or a
virtual DIT (Directory Information Tree)[X.501]. In the case of
subject names the domain is assumed to be at least the issuing domain
of the CA.
An unmistakable identity denotes a set of attributes and/or data
elements, which forms an identity that by unmistakable means relates
to a specific entity. The unmistakable connection between the
identity and the entity may be dependent on the context within which
the identity is formed. This context should however be evident for
any relying party given the information in the certificate. Some
contexts, such as when identities are based on pseudonyms, may
require assistance from the CA or a registration authority, to obtain
a corresponding officially registered identity under some predefined
circumstances, such as investigation of criminal offence.
3 Certificate and Certificate Extensions Profile
This section defines a profile for Qualified Certificates. The
profile is based on the Internet certificate profile RFC 2459 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 2459.
ASN.1 definitions relevant for this section that are not supplied by
RFC 2459 are supplied in Appendix A.
3.1 Basic Certificate Fields
This specification 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 contain an unmistakable identity of the
organization responsible for the certificate, and SHALL include a
registered name of the organization.
The unmistakable identity of the issuer SHALL be specified using an
appropriate subset of the following attributes:
domainComponent;
countryName;
stateOrProvinceName;
organizationName;
localityName; and
serialNumber.
Additional attributes MAY be present but they SHOULD NOT be necessary
to identify the issuing organization.
Many client implementations presuppose presence of a commonName
attribute value in the issuer field, containing relevant information
about the Issuer and the scope of the certificate. Certificates aimed
for public use SHOULD therefore always use the commonName attribute
to store information, which gives users reasonable guidance on the
nature of the certificate.
The legal jurisdiction for the issuing CA SHOULD be consistent with
the issuer name.
It should be noted, however, that 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 and legal jurisdiction.
3.1.2 Subject
Certificates compliant with this profile SHALL at the same time
specify a distinguished name and an unmistakable identity of the
subject (see 2.4 for definition of distinguished name and
unmistakable identity).
Attributes stored in the subject field SHALL at least form a
distinguished name of the subject, but they MAY also specify a
complete unmistakable identity. Relying parties MAY however have to
examine information stored in the subject alternative name extension
and the subject directory attributes extension in order to determine
a complete unmistakable identity of the subject.
The subject field SHALL contain an appropriate subset of the
following attributes:
countryName;
commonName;
surname;
givenName;
pseudonym;
serialNumber;
organizationName;
organizationalUnitName;
stateOrProvinceName
localityName and
postalAddress.
Other attributes may be present but MUST NOT be necessary to
distinguish the subject name from other subject names within the
issuer domain.
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.
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 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. Certificates aimed for public use
SHOULD therefore always include the commonName attribute even if
givenName, surname or pseudonym attributes are present.
The surname and givenName attribute types SHALL, if present, contain
the registered name of the subject, depending on the laws under which
the CA prepares the certificate. These attributes SHALL be used in
the subject field if the commonName attribute is not present. In
cases where the subject only has a single name registered, the
givenName attribute SHALL be used and the surname attribute SHALL be
omitted.
The pseudonym attribute type SHALL, if present, contain a pseudonym
of the subject, which SHALL be part of the subject's unmistakable
identity (as defined in Section 2.4). 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 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 associated.
The type of association between the organization and the subject is
beyond the scope of this document.
The postalAddress, the stateOrProvinceName and the localityName
attribute types SHALL, when present, be used to store address and
geographical information with which the subject is associated. If an
organizationName value also is present then the postalAddress,
stateOrProvinceName and localityName attribute values SHALL be
associated with the specified organization. The type of association
between the postalAddress, 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 specification provides additional details regarding the contents
of five certificate extensions. These extensions are the subject
directory attributes, certificate policies, key usage, private
extension for biometric information and private extension for
Qualified Certificate statements.
3.2.1 Subject Directory Attributes
The subjectDirectoryAttributes extension MAY contain additional
attributes, associated with the subject, as 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, which MAY
still be useful for the purpose of authorization and/or for
determining a global unmistakable identity of the subject.
This extension SHALL NOT be marked critical.
Compliant implementations SHALL be able to interpret the following
attributes:
title;
dateOfBirth;
placeOfBirth;
gender;
countryOfCitizenship; and
countryOfResidence.
Other attributes MAY be included according to local definitions.
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 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 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" and for males the
value "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 country of
citizenship at the time that the certificate was issued. If the
subject is a citizen of more than one country, more than one country
MAY be present. 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
the subject is a resident of more than one country, more than one
country MAY be present. Determination of residence is a matter of
law and is outside the scope of this document.
3.2.2 Certificate Policies
The certificate policies extension 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.
A statement by the issuer stating the purpose of the certificate as
discussed in Section 2.2 SHOULD be evident through indicated
policies.
In order to enhance path validation based on policy object
identifiers any statement related to Qualified Certificates, as
defined in 3.2.5, SHOULD also be defined by included certificate
policies.
Certificate policies MAY be combined with any qualifier defined in
RFC 2459.
3.2.3 Key Usage
The key usage extension SHALL be present. If the key usage
nonRepudiation bit is asserted then it SHOULD NOT be combined with
any other key usage , i.e. if set, the key usage non-repudiation
SHOULD be set exclusively.
The key usage extension MAY be marked critical.
3.2.4 Biometric Information
This section defines an 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 means for authentication
of biometric information. The biometric information that corresponds
to the stored hash is not stored in this extension, but the extension
MAY include an URI pointing to a location where this information can
be obtained. If included, this URI does not imply that this is the
only way to access this information.
It is RECOMMENDED that biometric information in this extension are
limited to information types suitable for human verification, i.e.
where decision whether the information is an accurate representation
of the subject, is naturally performed by a physical 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.
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 only be
calculated over the image data excluding any labels defining the
image type.
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 only be calculated over the image data
excluding any labels defining the image type.
3.2.5 Qualified Certificate Statements
This section defines an extension for inclusion of defined statements
related to Qualified Certificates.
A typical 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.
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.
qcStatements EXTENSION ::= {
SYNTAX QcStatementsSyntax
IDENTIFIED BY id-pe-qcStatements }
id-pe-qcStatements OBJECT IDENTIFIER ::= { id-pe 3 }
QcStatementsSyntax ::= SEQUENCE OF QcStatement
QcStatement ::= SEQUENCE {
statementId QC-STATEMENT.&Id({SupportedStatements}),
statementInfo QC-STATEMENT.&Type
({SupportedStatements}{@statementId}) OPTIONAL }
SupportedStatements QC-STATEMENT ::= { qcStatement-1,...}
3.2.5.1 Predefined Statements
This profile includes one predefined object identifier (id-qcs-
pkixQCSyntax-v1), identifying conformance with syntax and semantics
defined in this profile. This Qualified Certificate profile is
referred to as version 1.
qcStatement-1 QC-STATEMENT ::= { SemanticsInformation IDENTIFIED
BY id-qcs-pkixQCSyntax-v1 }
-- This statement identifies conformance with syntax and
-- semantics defined in this Qualified Certificate profile
-- (Version 1). The SemanticsInformation may optionally contain
-- additional semantics information as specified.
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.
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
then at least one of the fields semanticsIdentifier and
nameRegistrationAuthorities must be present, as indicated.
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 issues
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 private key is shared among entities, or the means
to use the private key is not protected against unintended usage.
This implies that the CA must perform proof-of-possession of the
private key. In addition, it implies that the CA have some knowledge
about the subject's cryptographic module.
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 and
this specification therefore recommends against such practices.
Comparing two qualified certificates to determine if they represent
the same physical entity may provide misleading results and should be
performed with care.
This specification is a profile of RFC 2459. The security
considerations section of that document applies to this specification
as well.

APPENDICES
A. ASN.1 definitions
As in RFC 2459, ASN.1 modules are supplied in two different variants
of the ASN.1 syntax.
Appendix A.1 is in the 1988 syntax, and does not use macros. However,
since the module imports type definitions from modules in RFC 2459
which are not completely in the 1988 syntax, the same comments as in
RFC 2459 regarding its use applies here as well; i.e. Appendix A.1
may be parsed by an 1988 ASN.1-parser by removing the definitions for
the UNIVERSAL types and all references to them in RFC 2459's 1988
modules.
Appendix A.2 is in the 1993 syntax. However, since the module imports
type definitions from modules in RFC 2459 which are not completely in
the 1993 syntax, the same comments as in RFC 2459 regarding its use
applies here as well; i.e. Appendix A.2 may be parsed by an 1993
ASN.1-parser by removing the UTF8String choice from the definition of
DirectoryString in the module PKIX1Explicit93 in RFC 2459. Appendix
A.2 may be parsed "as is" by an 1997 ASN.1 parser, however.

B. A Note on Attributes
This document defines several new attributes, both for use in the
subject field of issued certificates and in the
subjectDirectoryAttributes extension. In the interest of conformity,
they have been defined here using the ASN.1 ATTRIBUTE definition from
RFC 2459, which is sufficient for the purposes of this document, but
greatly simplified in comparison with ISO/ITU's definition. A
complete definition of these new attributes (including matching
rules), along with object classes to support them in LDAP-accessible
directories, can be found in [PKCS 9].
C. Example Certificate
Editor's note: This example will be updated (to reflect the decision
to use the subjectDirectoryAttributes extension rather than the
subjectAlternativeName extension) before publication of this memo as
an RFC.
This section contains the ASN.1 structure and a hex dump of a 817
byte version 3 qualified certificate. The certificate contains the
following information:
1. The serial number is 1
2. The certificate is signed with RSA and the SHA-1 hash algo-
rithm
3. The issuer's distinguished name is O=GMD - Forschungszentrum
Informationstechnik GmbH, C=DE
4. The subject's distinguished name is CN=Petra M. Gloeckner,
O=GMD - Forschungszentrum Informationstechnik GmbH, C=DE
5. The certificate was issued on July 6, 1999 and will expire on
July 6, 2000
6. The certificate contains a 1024 bit RSA key
7. The certificate includes a critical key usage extension
exclusively indicating non-repudiation
8. The certificate includes a certificate policy identifier
indicating the practices and procedures undertaken by the
issuing CA (object identifier 1.3.36.8.1.1). The certificate
policy object identifier is defined by TeleTrust, Germany. It
is required to be set in a certificate conformant to the
german digital signature law.
9. The certificate includes one subject alternative name - a
PersonalData structure (object identifier 1.3.6.1.5.5.7.8.1)
in the OtherName sub-field containing the following
attributes:
Registered by: municpality@seeheim.de
surname: Gloeckner
given name: Petra
date of birth: October, 14th 1971 (object identifier
1.3.6.1.5.5.7.9.1)
place of birth: Darmstadt (object identifier
1.3.6.1.5.5.7.9.2)
country of citizenship:DE (object identifier
1.3.6.1.5.5.7.9.5)
gender: female (object identifier
1.3.6.1.5.5.7.9.4)
10. The certificate includes a qualified statement (object
identifier 1.3.6.1.5.5.7.1.3) indicating a maximum reliance
limit of DM 5000,-. Therefore the monetary value has been used
which has been defined by ISO (object identifier
1.2.840.10052.1.1):
currency: 280 (=DEM)
amount: 5
exponent: 3
