1. Background

The implementation of a Swedish infrastructure for electronic identification and electronic signature requires various types of identifiers to represent objects in protocols and data structures.

This document defines the structure for identifiers assigned by the Sweden Connect Framework and provides a registry for assigned identifiers.

The following types of identifiers are assigned in this document:

• URI (Uniform Resource Identifier)

• OID (Object Identifier)

This registry is limited to registering assigned identifiers. Identifiers in this registry are typically defined within the context of a separate specification, which defines the semantic meaning of the identifier within the context of a particular protocol and/or data structure. Where applicable, this registry provides references to the documents where the exact meaning of each identifier is defined.

2. Structure

The basic structure of identifiers assigned by the Sweden Connect Framework is based on the following components:

2.1. URI Identifiers

All URI identifiers in this registry are of URL type (Uniform Resource Locator), assigned under the prefixes http://id.elegnamnden.se and http://id.swedenconnect.se.

These URL identifiers are defined using the following structure:

• http://id.elegnamnden.se/{category}[/{version}]/{identifier}, or,
• http://id.swedenconnect.se/{category}[/{version}]/{identifier}.

2.2. OID Identifiers

An object identifier consists of a node in a hierarchically-assigned namespace, formally defined using the ITU-T's ASN.1 standard, X.690. Successive numbers of the nodes, starting at the root of the tree, identify each node in the tree. Designers set up new nodes by registering them under the node's registration authority. The root of the tree contains the following three arcs:

• 0: ITU-T
• 1: ISO
• 2: joint-iso-itu-t

Object identifiers are in this document represented as a string containing a sequence of integers separated by a dot (“.”), e.g. 2.3.4.25, where each integer represents a node in the hierarchy.

The node assigned to the Swedish E-identification Board/Sweden Connect is: 1.2.752.201.

This represents a hierarchical structure of nodes in the following sequence:

• 1 = ISO
• 2 = ISO member body
• 752 = The Swedish Standardization Institute (SIS-ITS)
• 201 = Swedish E-identification Board (see note below)

This node is used as the Prefix (root node) for all OID identifiers in this registry, using the following structure:

1.2.752.201.{category}.{identifier}

OID identifiers according to this structure assign a node for each category and an identifier node under this category node. No node in this structure is assigned as version node. Version is handled, when necessary, within the identifier portion of the OID, typically by assigning a new identifier.

Note: The OID 1.2.752.201 was assigned to the Swedish E-identification Board, but this organisation has been overtaken by the Swedish Agency for Digital Government (Digg) who now uses this OID arc for the Sweden Connect Framework.

3. Assigned Identifiers

3.1. URL Identifiers

The following category codes are defined:

3.1.1. Authentication Context URIs

Authentication Context URIs representing assurance levels (Tillitsnivåer) relevant to [SE.Trust], [SC.SAML.Profile] and [SC.OIDC.Profile].

NOTE: eIDAS assurance levels low, substantial and high have the following AuthnContextClassRef URI:s defined by the EU commission:

• http://eidas.europa.eu/LoA/low

• http://eidas.europa.eu/NotNotified/LoA/low (for non-notified eID schemes)

• http://eidas.europa.eu/LoA/substantial

• http://eidas.europa.eu/NotNotified/LoA/substantial (for non-notified eID schemes)

• http://eidas.europa.eu/LoA/high

• http://eidas.europa.eu/NotNotified/LoA/high (for non-notified eID schemes)

[*]: The authentication context URI:s are intended to be used to represent authentication over the eIDAS authentication framework using an official eIDAS-connector. Authorization to issue assertions using these authentication context URI:s is determined by declaration of the "assurance certification" for the connector.

3.1.1.1. Authentication Context URIs for Swedish Non-residents

The Swedish assurance framework, [SE.Trust], states that a Swedish eID according to any of the defined assurance levels must only be issued to an individual holding a Swedish personal identity number (personnummer) or a Swedish coordination number (samordningsnummer).

In some cases, a certified eID-issuer may also issue eIDs to persons that do not hold a Swedish identity number (non-residents). If this is the case, and the original identification of the person has a strength that corresponds to the requirements put in [SE.Trust], a certified Identity Provider or OpenID Provider MAY use the URIs defined below:

Note: An Identity Provider, or OpenID Provider, that includes any of the above URIs in an issued assertion/ID Token, MUST NOT provide the Swedish personal identity number as an identity attribute/claim. This is per definition since these URIs are intended to be used for non-residents (i.e., they do not hold a Swedish identity number).

3.1.1.2. Authentication Context URIs for Uncertified Providers

The assurance levels defined in section 3.1.1 may only be used by Identity Providers, or OpenID Providers, that have been reviewed and approved by the Swedish Agency for Digital Government (Digg) according to [SE.Trust]. For providers that have not undergone a review process but make a self declaration to be compliant with [SE.Trust] this specification defines the following authentication context URIs:

Proxy providers that have eIDAS authentication as an option MUST NOT use the eIDAS authentication context URIs defined in section 3.1.1, instead they should use:

3.1.2. Attribute Sets

Identifiers for attribute sets defined in the Sweden Connect SAML Attribute Specification.

3.1.3. Entity Category Identifiers

Identifiers for categories of service entities, specified as an “Entity Attribute” in the SAML federation metadata.

3.1.3.1. Service Entity Categories

Identifiers for entity categories representing alternative sets of requirements.

3.1.3.2. Entity Categories for Service Properties

Identifiers for defined service properties.

3.1.3.3. Entity Categories for Service Type

Identifiers for defined service types.

3.1.3.4. Entity Categories for Service Contract

Service Contract Entity Category identifiers are indented for performing service matching based on contracts, or business agreements, between providing and consuming services.

All Service Contract identifiers are prefixed with http://id.swedenconnect.se/contract/<org>, where org is the identifier for the defining organization.

The Sweden Connect Framework specifications do not define any Service Contract identifiers, instead the federation operator, or other parties, may define identifiers suitable for representing how consuming and providing services should be matched based on their respective agreements.

3.1.3.5. General Entity Categories

An entity category of the General Entity Category type is a category that does not fit into any of the other category types regarding definitions and matching rules.

General category identifiers are prefixed with http://id.swedenconnect.se/general-ec.

3.1.4. SAML Protocol Status Codes

Status code identifiers for use in SAML Response messages. The list below extends the list of second-level status codes defined in section 3.2.2.2 of [SAML2Core].

3.1.5. Central Signing

Identifiers used in the protocol for requesting services form a central signing service.

3.1.6. Authentication Context

Identifiers associated with the Authentication Context X.509 extension

3.1.7. Sign Response Status Codes

Status code identifiers for the DSS Extension for Central Signing services. The following identifiers provide defined status codes for inclusion in a <ResultMinor> element of the <Result> element of a sign response message according to the OASIS standard “Digital Signature Service Core Protocols, Elements, and Bindings Version 1.0” [OASIS-DSS].

3.1.8. Name Registration Authorities

Some protocols require a URI identifier to uniquely identify the entity responsible for a particular namespace.

[*]: This also covers the Swedish Agency for Digital Government (Digg) which has overtaken the Swedish E-identification Board's assignments.

3.1.9. eIDAS Identifiers

This section defines identifiers used within the Sweden Connect Framework to integrate with the eIDAS Framework.

3.1.9.1. eIDAS Proxy Service Aliases

Each country within the eIDAS federation provides an eIDAS Proxy Service that is a Proxy Identity Provider for the authentication services within that specific country. The entityID identifier for an eIDAS Proxy Service in another country is not known to a Swedish Service Provider, but there are cases in which the Swedish Service Provider needs to refer to a specific eIDAS Proxy Service. Therefore, this specification defines a URI identifier format for eIDAS Proxy Service aliases. The format is as follows:

http://id.swedenconnect.se/eidas/1.0/proxy-service/{country-code}

where {country-code} is the country identifier in ISO 3166-1 alpha-2 format [ISO 3166].

A consumer of an eIDAS Proxy Service alias URI MUST accept the country code part of the URI in both lower and upper case letters.

3.1.9.2. eIDAS Connector Aliases

A Swedish SAML Identity Provider, or OpenID Provider, that delivers authentication services to eIDAS, via the Swedish eIDAS Proxy Service, will receive the identifier of the Service Provider from another country that has requested user authentication, along with an "eIDAS Connector alias" URI telling in which country the requesting Service Provider resides.

For SAML, the entityID of the Service Provider is delivered in a <saml2p:RequesterID> element of the authentication request, and the eIDAS Connector alias is delivered in another RequesterID element.

For OpenID Connect, both identifiers are delivered in the https://id.oidc.se/param/originalClientId authentication request parameter, see Section 2.3.1 of [OIDC.Sweden.ReqPar]. The parameter value holds the identifier of the Service Provider followed by the eIDAS Connector alias, separated by a semicolon (;).

The format of this alias is as follows:

http://id.swedenconnect.se/eidas/1.0/connector/{country-code}

where {country-code} is the country identifier in ISO 3166-1 alpha-2 format [ISO 3166].

A consumer of an eIDAS Connector alias URI MUST accept the country code part of the URI in both lower and upper case letters.

3.1.9.3. Identity Binding Processes

Section 3.3.2 of [SC.SAML.Attrs] describes how the personalIdentityNumberBinding attribute is assigned with one or more "Identity Binding Process URI:s" after an identity binding. The possible values are:

The Binding eIDAS Identities to Records in the Swedish Population Register ([ID-Binding]) document defines the above processes in detail.

3.1.10. OpenID Federation Identifiers

This section contains identifiers defined by Sweden Connect for use in OpenID Federation.

3.1.10.1. Trust Mark Type Identifiers

Section 5.2 of [SC.OIDF.Rules] defines a set of Trust Mark Types used in the Sweden Connect OpenID Federation deployment.

3.1.10.2. Registration Policy Identifiers

Section 6 of [SC.OIDF.Rules] defines a set of Registration Policy identifiers for use in the Sweden Connect OpenID Federation deployment.

3.2. OID Identifiers

Defined categories:

The following OIDs are defined in the ASN.1 declarations in 3.2.1:
