1. Introduction

This document specifies an attribute profile for the Swedish eID Framework. The attribute profile defines attributes for use within the Swedish eID Framework, and a number of defined attribute sets that may be referenced by other documents as means to specify specific attribute release requirements.

1.1. Terminology

Term Defined meaning
Attribute A property, quality or characteristic of a person, thing or object. This term is used in general in this specification to denote an attribute of a person/entity that is represented by a set of attributes in a SAML attribute statement (see SAML Attribute). This term is also used in this specification when describing XML syntax to denote an attribute (property) of an XML element.
SAML attribute An attribute of an entity represented by a set of attributes in a SAML attribute statement (<saml:AttributeStatement> element).
IDP Identity Provider
SP Service Provider
Natural person Natural person is legal term for a real human being, as opposed to a legal person, which may be a private (i.e., business entity) or public (i.e., government) organization.
Civic registration number A unique identifier assigned to each natural person in a national population register. Within the context of this specification this is a Swedish ”personnummer” or ”samordningsnummer” according to [SKV704] and [SKV707].

1.2. Requirement key words

The key words “MUST”, “MUST NOT”, “REQUIRED”, “SHALL”, “SHALL NOT”, “SHOULD”, “SHOULD NOT”, “RECOMMENDED”, “MAY”, and “OPTIONAL” are to be interpreted as described in [RFC2119].

These keywords are capitalized when used to unambiguously specify requirements over protocol features and behavior that affect the interoperability and security of implementations. When these words are not capitalized, they are meant in their natural-language sense.

1.3. Name space references

Conventional XML namespace prefixes are used throughout the listings in this specification to stand for their respective namespaces as follows, whether or not a namespace declaration is present in the example:

Prefix XML Namespace Comments
saml urn:oasis:names:tc:SAML:2.0:assertion The SAML V2.0 assertion namespace, defined in the schema [SAML-XSD].
xs http://www.w3.org/2001/XMLSchema The XML Schema namespace, representing definitions of data types in [XML-Schema].

1.4. Structure

This specification uses the following typographical conventions in text: <ns:Element>, Attribute, Datatype, OtherCode.

2. Attribute Sets

This section defines attribute sets based on attribute definitions in section 3. Common to all attribute sets is that each attribute MUST NOT be present more than once. An attribute that has more than one value MUST be provided as one attribute with multiple <AttributeValue> sub-elements in accordance with section 3.1.

An identifier, named “Attribute Set Identifier”, and an URI, are defined for each attribute set as means for other documents to reference specific attribute sets.

Each attribute set defines a number of mandatory attributes that MUST be released by an Attribute Provider* that provides attributes according to the given attribute set, and optionally recommended attributes that SHOULD be released as part of the attribute set if they are available to the provider.

Note: An Attribute Provider may also release other attributes, not specified by the defined attribute sets it supports. See further section 6.2.1, “Attribute Release Rules”, of “Deployment Profile for the Swedish eID Framework” ([EidDeployProf]).

In order to comply with a defined attribute set, the following attribute requirements apply:

Attribute requirement Definition
REQUIRED Attributes that MUST be present.
RECOMMENDED Attributes that SHOULD be present, if available.

A defined attribute set does not define any rules for attributes other than those listed as required or recommended.

[*]: An Attribute Provider is an entity that releases attributes to a requesting entity. In all practical cases within the Swedish eID Framework this entity is an Identity Provider or an Attribute Authority. Within the eIDAS Framework, the Swedish eIDAS node acts as the Attribute Provider for the Service Providers.

2.1. Pseudonym Identity

Attribute set identifier: ELN-AP-Pseudonym-01

URI: http://id.elegnamnden.se/ap/1.0/pseudonym-01

This attribute set specifies the condition where there are no mandatory or recommended attributes.

Typical use: In a pseudonym attribute release policy that just provides a persistent NameID identifier in the assertion but no attributes.

2.2. Natural Personal Identity without Civic Registration Number

Attribute set identifier: ELN-AP-NaturalPerson-01

URI: http://id.elegnamnden.se/ap/1.0/natural-person-01

The “Personal Identity without Civic Registration Number” attribute set provides basic natural person information without revealing the civic registration number of the subject.

Attribute requirement Attributes
REQUIRED sn (Surname)
givenName (Given name)
displayName (Display name)

Typical use: In an attribute release policy that provides basic user name information together with a persistent NameID identifier in the assertion.

2.3. Natural Personal Identity with Civic Registration Number (Personnummer)

Attribute set identifier: ELN-AP-Pnr-01

URI: http://id.elegnamnden.se/ap/1.0/pnr-01

The “Personal Identity with Civic Registration Number” attribute set provides basic personal identity information including a Swedish civic registration number of the subject.

Attribute requirement Attributes
REQUIRED sn (Surname)
givenName (Given name)
displayName (Display name)
personalIdentityNumber (National civic registration number)
RECOMMENDED dateOfBirth (Date of birth)

Typical use: In an attribute release policy that provides basic user name information together with the person’s Swedish civic registration number.

2.4. Organizational Identity for Natural Persons

Attribute set identifier: ELN-AP-OrgPerson-01

URI: http://id.elegnamnden.se/ap/1.0/org-person-01

The “Organizational Identity for Natural Persons” attribute set provides basic organizational identity information about a person. The organizational identity does not necessarily imply that the subject has any particular relationship with or standing within the organization, but rather that this identity has been issued/provided by that organization for any particular reason (employee, customer, consultant, etc.)

Attribute requirement Attributes
REQUIRED sn (Surname)
givenName (Given name)
displayName (Display name)
orgAffiliation (Personal identifier and organizational identifier code)
o (Organization name)
RECOMMENDED organizationIdentifier (Organizational identifier code)
ou (Organizational unit name)

Typical use: In an attribute release policy that provides basic organizational identity information about a natural person.

2.5. eIDAS Natural Person Attribute Set

Attribute set identifier: ELN-AP-eIDAS-NatPer-01

URI: http://id.elegnamnden.se/ap/1.0/eidas-natural-person-01

The “eIDAS Natural Person Attribute Set” provides personal identity information for a subject that has been authenticated via the eIDAS Framework.

Attribute requirement Attributes
REQUIRED* prid (Provisional ID)
pridPersistence (Provisional ID persistence indicator)
eidasPersonIdentifier (Mapping of the eIDAS PersonIdentifier attribute)
dateOfBirth (Date of birth)
sn (Surname)
givenName (Given name)
c (Country code for the eIDAS country that authenticated the subject)
transactionIdentifier (ID of assertion issued by the member state node)**
REQUIRED
(if available)***
birthName (Birth name)
placeOfBirth (Place of birth)
eidasNaturalPersonAddress (Address for natural person)
gender (Gender)
RECOMMENDED personalIdentityNumber (National civic registration number)
personalIdentityNumberBinding (National civic registration number Binding URI)

Typical use: In an attribute release policy implemented by an eIDAS connector that provides a complete set of attributes to a requesting Service Provider.

Note: The personalIdentityNumber and personalIdentityNumberBinding attributes will be part of the attribute release if the attribute provider has access to enough information to provide a reliable binding between eIDAS attributes and an Swedish identity number (see section 3.3.2).

The eIDAS attribute set comprises of “added” and “converted” attributes.

Added attributes: Attributes that are not provided by the member state node, but added by the Swedish eIDAS node in order to provide additional information about the authenticated subject obtained from relevant domestic attribute sources. The prid, pridPersistence and personalIdentityNumber attributes are “added attributes”.

Converted attributes: Attributes that are the result of a conversion process where an eIDAS attribute is converted into a single-value string type attribute defined within the Swedish eID Framework (see section 3.3.3, “Conversion of eIDAS Attributes”). The reason for the conversion is to facilitate processing for attribute consumers. The eIDAS attributes are not simple string types, and this affects interoperability in a negative way since standard SAML software need to be modified to support these attributes. Therefore, the Swedish eID node will convert eIDAS attributes to their corresponding string value-typed attributes. The eidasPersonIdentifier, sn, givenName and dateOfBirth attributes are examples of “converted attributes”.

[*]: Attributes “added” by the Swedish eID node and converted attributes for the mandatory attributes of the eIDAS minimum data set for natural persons.

[**]: The transaction identifier attribute will contain the unique ID of the assertion that was issued by the member state node. This information together with the entityID of the member state node (found in the <saml2:AuthenticatingAuthority> element of an assertion) give a reference to the original assertion and authentication process.

[***]: Converted attributes for the optional attributes of the eIDAS minimum data set for natural persons.

2.6. Natural Person Identity with HSA-ID

Attribute set identifier: DIGG-AP-HSAid-01

URI: http://id.swedenconnect.se/ap/1.0/hsaid-01

The “Natural Person Identity with HSA-ID” attribute set provides basic personal identity information including a HSA-ID of the subject (see [SambiAttr]).

Attribute requirement Attributes
REQUIRED sn (Surname)
givenName (Given name)
displayName (Display name)
employeeHsaId (HSA-ID)
RECOMMENDED dateOfBirth (Date of birth)

Typical use: In an attribute release policy that provides basic user name information together with the person’s HSA-ID.

All attributes, unless stated otherwise in this table, holds string values using the UTF-8 character set using the xs:string data type. Certain attributes such as mail, personalIdentityNumber, organizationIdentifier, telephoneNumber and mobile use a restricted character set according to its defined usage within this specification.

All attributes use the “caseIgnoreMatch” matching rule as defined by X.520 [X.520]. That is, case-insensitive comparison where insignificant spaces are ignored.

Attributes with a “NO” value in the multivalued column MUST NOT have more than one <AttributeValue> sub-element. Attributes with a “YES” value in the multivalued column MAY have one or more <AttributeValue> sub-elements.

3.2. SAML Attribute Format

The <saml:Attribute> element representing an attribute in 3.1 SHALL comply with the following requirements:

The following is an example of the surname attribute. Its name is “urn:oid:2.5.4.4”, its friendly name is “sn” and the value is represented using a string type.

<saml2:Attribute xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                           FriendlyName="sn"
                           Name="urn:oid:2.5.4.4"
                           NameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:uri">
  <saml2:AttributeValue xsi:type="xs:string">Eriksson</saml2:AttributeValue>
</saml2:Attribute>

3.2.1. The authContextParams Attribute

The attribute authContextParams holds key-value pairs. Its purpose is to store key-value pairs representing data from an authentication process. The data stored in this attribute is generally not defined by the Swedish eID Framework, but instead by the issuing party (i.e., the Identity Provider).

The authContextParams attribute is a non-empty single-value attribute where the attribute value contains the key-value pairs separated by semicolons. The key and value of each pair is separated by a ‘=’ character and both the key and value MUST be URL-encoded.

Below follows an example of how the authContextParams attribute is populated with two key-value pairs, "foo" that stores the value "ÅÄÖ", and "bar" that stores the value "123".

...
<saml2:Attribute xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    
                           FriendlyName="authContextParams"
                           Name="urn:oid:1.2.752.201.3.3"
                           NameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:uri">
  <saml2:AttributeValue xsi:type="xs:string">foo=%C3%85%C3%84%C3%96;bar=123</saml2:AttributeValue>
</saml2:Attribute>
...

3.2.2. The userCertificate, userSignature and authServerSignature Attributes

Identity Providers that implement a PKI-based authentication method may make use of the userCertificate and userSignature attributes.

The userCertificate attribute holds, as its value, a base64-encoding of the X.509 certificate presented by the subject during authentication.

The userSignature attribute contains a base64-encoding of a signature object that was created by the subject during the authentication* process.

The authServerSignature may be included in assertions in cases where there are requirements to include a digitally signed proof from the authentication server at which the end user authenticated. This is mainly useful in cases where the SAML Identity Provider delegates end user authentication to a subordinate authentication server.

[*]: Note that an authentication process, may be “authentication for signature” as specified in section 7 of [EidDeployProf].

3.2.3. The sad Attribute

The sad attribute holds Signature Activation Data that is required by a signature service in order to service a signature request in accordance with CEN EN 419 241-2. The sad attribute holds a single string attribute value. The format of the string value is defined in the "Signature Activation Protocol for Federated Signing" specification [SigSAP].

3.2.4. The signMessageDigest Attribute

The signMessageDigest attribute is included in an assertion as a proof that an Identity Provider displayed a sign message for the user and that the user actively confirmed acceptance of this sign message. This sign message is the SignMessage extension that may be included in an authentication request by Signature Service Service Providers. See section 7 of [EidDeployProf] for details.

The attribute value format for the signMessageDigest attribute is digest-algorithm-identifier;sign-message-digest, where digest-algorithm-identifier is the XML Security algorithm URI identifier of the selected digest algorithm and sign-message-digest is base64(digest(msg)). The msg is the UTF-8 encoded bytes of the sign message that was displayed. It equals the csig:Message element value of the csig:SignMessage ([DSSExt]). Thus, if the csig:Message element is encrypted into a csig:EncryptedMessage, the element value after decryption should be used.

Entities compliant with this specification MUST use http://www.w3.org/2001/04/xmlenc#sha256 as the digest algorithm, unless the recipient of the signMessageDigest attribute has declared another digest algorithm as preferred in its metadata entry (see section 2.1.1.3 of [EidDeployProf]). In those cases this algorithm MAY be used.

Example:

Suppose that the unencrypted message is "I hereby confirm that I want to join example.com as a customer". This is represented as:

<csig:Message>
  SSBoZXJlYnkgY29uZmlybSB0aGF0IEkgd2FudCB0byBqb2luIGV4YW1wbGUuY29tIGFzIGEgY3VzdG9tZXI=
</csig:Message>

The input to the digesting operation is the value bytes of the csig:Message element which is UTF-8 encoded bytes of the actual sign message*.

The signMessageDigest attribute for the above example will then be:

<saml2:Attribute FriendlyName="signMessageDigest" Name="urn:oid:1.2.752.201.3.14"
  NameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:uri">
  <saml2:AttributeValue xsi:type="xsd:string">
    http://www.w3.org/2001/04/xmlenc#sha256;0yKaSVsYeh+PX2Q6diqO2w89+a3Dm303tp3AVjgxwj0=
  </saml2:AttributeValue>
</saml2:Attribute>

3.3. Attributes for the eIDAS Framework

3.3.1. The prid and pridPersistence Attributes

Assertions (with attribute statements) issued from a member state eIDAS node contain a set of attributes identifying the authenticated subject. Attributes obtained from other conformant eIDAS nodes will provide an eIDAS unique identifier but it can not be ruled out that the Swedish eIDAS node may be adopted to accept authentication from non eIDAS compliant nodes, such as when accepting authentication from countries outside of EU such as the USA.

Therefore, the Swedish eIDAS connector enriches attribute statements with the provisional ID (prid) and provisional ID persistence (pridPersistence) attributes.

The prid attribute is designed to provide one common unique attribute of the user in a common format regardless of the composition of the original attributes received from the authenticating source. The prid attribute value is not stored in any registry, but derived from the received attributes at each authentication instant according to defined algorithms specified in [ConstructedAttr]. The algorithm ensures that each prid is unique for each authenticated entity, but does not ensure persistence. If the attributes received for an entity changes over time, the prid attribute may also change dependent on the defined prid generation algorithm for that attribute source.

The pridPersistence attribute provides an indication of the expected persistence over time for a present prid attribute value. The value of this attribute is determined from the selected prid generation algorithm in combination with the attribute source. For example, a prid derived from a Norwegian eIDAS unique identifier has longer persistence expectancy than a prid derived from the same attribute from the UK or Germany. This attribute helps Service Providers to apply different UI and service functions for users with different persistence expectancy. This may assist users with low persistence expectancy to regain control of their user account, should their prid change in the future.

The specification “eIDAS Constructed Attributes Specification for the Swedish eID Framework”, [ConstructedAttr], declares the details for how the prid and pridPersistence attributes are generated and how they should be processed.

3.3.2. The personalIdentityNumberBinding Attribute

When an authentication for a natural person is performed against the eIDAS Framework the personalIdentityNumber attribute (Swedish “personnummer” or “samordningsnummer”) MAY be included in the assertion being delivered to the requesting Service Provider. The member state eIDAS node does not provide this attribute, but instead the assertion may be extended by the Swedish eIDAS connector, that in some cases knows how to map from the eIDAS attributes to a personalIdentityNumber attribute.

This binding can be performed using a number of different processes, where some are considered to be strong and where others only may be a “good guess”. Therefore, an eIDAS connector that extends an assertion with a personalIdentityNumber attribute MUST also include the personalIdentityNumberBinding attribute. This attribute contains a value that is an URI that identifies the process that was used to link a set of eIDAS attributes to a personalIdentityNumber attribute.

This specification does not specify any defined URI identifiers that may be included in this attribute. Such URI identifiers will be specified in documents specifying appropriate binding mechanisms.

3.3.3. Conversion of eIDAS Attributes

The attributes specified within eIDAS ([eIDAS_Attr]) does not use simple string type values. Instead each attribute is represented using its own dedicated XML data type. This affects interoperability in a negative way since most standard SAML software need to be modified to support these attributes. Therefore, the Swedish eID Framework defines mappings for all eIDAS attributes to attributes having definitions that are more suitable for processing using standard SAML software.

Below follows a listing of how the attributes for the eIDAS minimum data set for Natural Persons are converted into attributes supported by the Swedish eID Framework.

Note: When converting an eIDAS attribute that makes use of “transliteration” (as described in section 2.4 of [eIDAS_Attr]) attribute values having the LatinScript attribute set to false will not be part of the resulting attribute.

3.3.3.1. Conversion of eIDAS CurrentAddress

The eIDAS attribute CurrentAddress is defined in section 2.2.9 of [eIDAS_Attr]. Its value is a Base64-encoding of an XML-structure of the type CurrentAddressStructuredType.

<xsd:complexType name="CurrentAddressStructuredType">
  <xsd:annotation>
    <xsd:documentation>
      Current address of the natural person.
    </xsd:documentation>
  </xsd:annotation>
  <xsd:sequence>
    <xsd:element name="PoBox" type="xsd:string" minOccurs="0" maxOccurs="1"/>
    <xsd:element name="LocatorDesignator" type="xsd:string" minOccurs="0" maxOccurs="1"/>
    <xsd:element name="LocatorName" type="xsd:string" minOccurs="0" maxOccurs="1"/>
    <xsd:element name="CvaddressArea" type="xsd:string" minOccurs="0" maxOccurs="1"/>
    <xsd:element name="Thoroughfare" type="xsd:string" minOccurs="0" maxOccurs="1"/>
    <xsd:element name="PostName" type="xsd:string" minOccurs="0" maxOccurs="1"/>
    <xsd:element name="AdminunitFirstline" type="xsd:string" minOccurs="0" maxOccurs="1"/>
    <xsd:element name="AdminunitSecondline" type="xsd:string" minOccurs="0" maxOccurs="1"/>
    <xsd:element name="PostCode" type="xsd:string" minOccurs="0" maxOccurs="1"/>
  </xsd:sequence>
</xsd:complexType>

An example of an instance of a CurrentAddress attribute would look as follows:

<saml2:Attribute xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                           FriendlyName="CurrentAddress"

The value is the Base64-encoding of the following XML-snippet:

<eidas:LocatorDesignator>22</eidas:LocatorDesignator>
<eidas:Thoroughfare>Arcacia Avenue</eidas:Thoroughfare>
<eidas:PostName>London</eidas:PostName>
<eidas:PostCode>SW1A 1AA</eidas:Postcode>

This is not easily processed by standard SAML-software, and requires several steps including XML-decoding of an incomplete XML-snippet. Therefore, the Swedish eID Framework defines the eidasNaturalPersonAddress attribute to be used when the Swedish eIDAS node converts the eIDAS CurrentAddress attribute.

The eidasNaturalPersonAddress attribute is defined to be a non-empty single-value attribute containing key-value pairs separated by semicolons. The keys are element names from the CurrentAddressStructuredType type and the value-parts are their corresponding values. The key and value of each pair is separated by a ‘=’ character and both the key and value MUST be URL-encoded.

The eIDAS-attribute CurrentAddress above will thus be converted to the following attribute:

<saml2:Attribute xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                           FriendlyName="eidasNaturalPersonAddress"
                           Name="urn:oid:1.2.752.201.3.9"
                           NameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:uri">
  <saml2:AttributeValue xsi:type="xs:string">
    LocatorDesignator=22;Thoroughfare=Arcacia%20Avenue;PostName=London;PostCode=SW1A%201AA
  </saml2:AttributeValue>
</saml2:Attribute>
