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 Swedish eID 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 Swedish eID 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 Technical 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 [TillitRamv] and [EidDeploy].

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)

3.1.1.1. Sign Message Authentication Context URIs (deprecated)

DEPRECATED

The use of Sign Message Authentication Context URIs is deprecated. See section 7 of [EidDeploy] for details.

Authentication Context URIs extending the above URIs with specific meaning for use with authentication requests that includes a sign message that must be displayed to the user (see section 7 of [EidDeploy]).

URL	Object
http://id.elegnamnden.se/loa/1.0/loa2-sigmessage	Authentication according to assurance level 2 with extended requirements for displaying signature messages.
http://id.elegnamnden.se/loa/1.0/loa3-sigmessage	Authentication according to assurance level 3 with extended requirements for displaying signature messages.
http://id.swedenconnect.se/loa/1.0/ uncertified-loa3-sigmessage	Authentication according to uncertified-loa3, as defined above, with extended requirements for displaying signature messages.

http://id.elegnamnden.se/loa/1.0/eidas-nf-high-sigm	Authentication accordance to eIDAS assurance level high with an eID scheme that MUST be notified, with extended requirements for displaying signature messages.

3.1.2. Attribute Sets

Identifiers for attribute sets defined in the Attribute Profile Specification for the Swedish eID Framework.

3.1.3. Entity Category Identifiers

Identifiers for categories of service entities, specified as an “Entity Attribute” in the 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 Swedish eID 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.

3.1.4. 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 SAML based Central Signing service. 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 Swedish eID 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 an 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 Identity Provider that delivers authentication services to eIDAS, via the Swedish eIDAS Proxy Service, will receive the entityID of the Service Provider from another country that has requested user authentication in a <saml2p:RequesterID> element of the authentication request. Along with this information, the Swedish Proxy Service will also include another RequesterID element that holds the "eIDAS Connector alias" URI, telling from which country the requesting Service Provider resides.

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.

3.2. OID Identifiers
