1. Introduction
-
The primary purpose of this document is to provide a mechanism that allows an application to obtain information that expresses the identity of a subject in an X.509 certificate according to [RFC5280]. The identity is stored either in a subject field attribute, as a subject alternative name, or in a subject directory attribute.
The motivation for this work is to enable mapping of identity data between an identity system and a certificate where the identity system and the certificate are using different attributes and data formats to express the identity of the same entity. In such a scenario, the certificate subject already has an authenticated identity composed of a set of attributes, or so-called claims, that differ from the set of attributes that are commonly used to express the identity of a certificate subject and that may be governed by a specific certificate profile limiting that set.
A typical scenario motivating the definition of this extension arises when the source of user authentication and user identity is derived from a SAML [SAML] federation attribute profile. In a SAML federation, the subject presents a SAML assertion in exchange for a certificate that can be uniquely linked to information provided in the original SAML assertion, e.g., attributes and/or level of assurance indicators.
Such certificates are sometimes issued in order to provide the user with a means to create an electronic signature that ties the user to the SAML subject, its attributes, and level of assurance indicators.
If such a certificate needs to conform to a certificate profile such as [RFC3739], then this certificate may have to use a separate set of attributes to express the subject identity. The certificate also may have to employ a format for attribute values that is different from the set of attributes obtained from the SAML assertion.
The extension defined in the document makes it possible to represent information about the authentication context employed when authenticating the subject for the purpose of issuing a certificate. This may include information such as:
-
o the Identity Provider that authenticated the subject
o the level of assurance with which the subject was authenticated o the trust framework where this level of assurance was defined o a unique reference to the authentication instant
o a mapping between the subject attributes (obtained from the-
SAML assertion used to authenticate the subject) and the subject identity information placed in the issued certificate.
-
One scenario where this information may be useful arises when a user logs in to a service using SAML credentials, and the same user (at some point) is required to sign some information. The service may need to verify that the signature was created by the same user that logged on to the service. Today this is only possible using out-of- band knowledge about the Certification Authority (CA) that issued the certificate and its practices. However, this approach does not scale to a large number of service providers, identity providers, and CAs.
The extension defined here provides better scalability since it requires only the service provider to maintain a list of trusted CAs. All other information about the relationship between the certificate subject and the SAML authenticated subject is available in the certificate.
-
1.1. Terminology
-
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 [RFC2119].
2. Authentication Context Extension Syntax
-
The Authentication Context extension has the following syntax:
AuthenticationContexts ::= SEQUENCE SIZE (1..MAX) OF AuthenticationContext AuthenticationContext ::= SEQUENCE { contextType UTF8String, contextInfo UTF8String OPTIONAL }This extension holds a sequence of AuthenticationContext information. When present, this extension MUST include at least one AuthenticationContext.
The type of authentication context defined in AuthenticationContext is identified by the contextType. The contextType MUST contain a URI that identifies the context type as well as the data format and encoding of context information provided in contextInfo.
This extension MAY be marked critical.
Applications that find an authentication context information type they do not understand MUST ignore it if the extension is non- critical and MUST reject the certificate if the extension is marked critical. If an application requires that an authentication context exist, and either the extension is absent or none of the provided authentication contexts can be used, the end-user certificate fails validation.
This document defines one authentication context information type (Section 3) that is used to provide information about SAML-based authentication of the subject that was utilized in the certificate issuance process. Other documents can define other authentication context information types.
3. SAML Authentication Context Information
-
The SAML Authentication context information provides a contextType field that can be used to carry information about SAML-based authentication of the certified subject as utilized in the certificate issuance process.
The data carried in this authentication context information field is identified by the following XML schema ([Schema1] [Schema2]) name space:
http://id.elegnamnden.se/auth-cont/1.0/saci
When this URI is specified as contextType, the associated XML data provided in contextInfo MUST be provided in the form of an XML document [XML], represented by a string of UTF-8-encoded characters.
The XML document SHOULD exclude any unnecessary line breaks and white space, such as line indentation, to reduce its size as much as possible.
3.1. contextInfo Data Structure
-
The data provided in contextInfo SHALL contain XML that is UTF-8 encoded in accordance with the XML schema provided in Appendix B. The XML document string in contextInfo MUST NOT include an XML header. That is, the XML document string contains only the root element <SAMLAuthContext> with its child elements <AuthContextInfo> and <IdAttributes>.
The <AuthContextInfo> and <IdAttributes> elements are outlined in the following subsections.
3.1.1. AuthContextInfo Element
-
The <AuthContextInfo> element MAY be present. This element contains the following attributes:
-
IdentityProvider (required): The SAML EntityID of the Identity
-
Provider that authenticated the subject.
AuthenticationInstant (required): Date and time when the subject
-
was authenticated, expressed according to Appendix B.1.
-
-
AuthnContextClassRef (required): A URI identifying the
-
AuthnContextClassRef that is provided in the AuthnStatement of the Assertion that was used to authenticate the subject. This URI identifies the context and the level of assurance associated with this instance of authentication.
AssertionRef (optional): A unique reference to the SAML assertion.
ServiceID (optional): An identifier of the service that verified
-
the SAML assertion.
The <AuthContextInfo> element may hold any number of child elements of type any (processContents="lax"), providing additional information according to local conventions. Any such elements SHOULD be ignored if not understood.
-
3.1.2. IdAttributes Element
-
The <IdAttributes> element MAY be present. This element holds a sequence of one or more <AttributeMapping> elements, where each <AttributeMapping> element contains mapping information about one certificate subject attribute or name form present in the certificate.
Each <AttributeMapping> element MUST specify the following attributes:
-
Type:
-
A string containing one of the enumerated values "rdn", "san", or "sda", specifying the type of certificate attribute or name form for which mapping information is provided:
"rdn": Mapping information is provided for an attribute in a Relative Distinguished Name located in the subject field. "san": Mapping information is provided for a name in the Subject Alternative Name extension of the certificate. "sda": Mapping information is provided for an attribute in the Subject Directory Attributes extension. Ref: A reference to the specific attribute or name field. This reference is dependent on the value of Type in the following way: "rdn": Ref holds a string representation of the object identifier (OID) of the relative distinguished name attribute. "san": Ref holds a string representation of the explicit tag number of the Subject Alternative Name type (e.g., "1" = email address (rfc822Name) and "2" = dNSName). If the SubjectAlternative name is an otherName, then Ref holds a string representation of the OID defining the otherName form. "sda": Ref holds a string representation of the OID of the subject directory attribute attribute.-
-
String representations of object identifiers (OID) in the Ref attribute MUST be represented by a sequence of integers separated by a period, e.g., "2.5.4.32". This string contains only numerals (ASCII 0x30 to 0x39) and periods (ASCII 0x2E), and it MUST NOT contain any other characters.
-
Each <AttributeMapping> element MUST contain a <saml:Attribute> element as defined in [SAML]. This SAML attribute element MUST have a Name attribute (specifying its type), MAY have other attributes, and MAY have zero or more <saml:AttributeValue> child elements. A present SAML attribute with absent attribute value limits mapping to the type of SAML attribute that was used to obtain the value stored in the referenced certificate subject attribute or name form, without duplicating the actual attribute value.
If an attribute value is present in the SAML attribute, then the value stored in the certificate in the referenced attribute or name form MAY differ in format and encoding from the present SAML attribute value. For example, a SAML attribute value can specify a country expressed as "Sweden", while this country value is stored in the certificate in a countryName attribute using the two letter country code "SE".
Several <AttributeMapping> elements MAY be present for the same certificate subject attribute or name form if the certificate contains multiple instances of this attribute or name form where their values were obtained from different SAML attributes. However, in such cases, it is not defined which present subject attribute or name form maps to which SAML attribute. A certificate-using application MAY attempt to determine this by comparing attribute values stored in this extension with attribute or name values present in the certificate, but this specification does not define any explicit matching rules that would guarantee an unambiguous result.
The <AttributeMapping> element may hold any number of child elements of type any (processContents="lax"), providing additional information according to local conventions. Any such elements MAY be ignored if not understood.
Note:
-
-
The <AttributeMapping> element is designed to provide mapping between SAML attributes and certificate subject attributes and name forms where there is a distinct and clear relationship between relevant SAML attributes and corresponding certificate attributes and name forms. This does not cover all aspects of complex mapping situations. If more than one SAML attribute maps to the same certificate attribute or if structured multivalued attributes are split into a range of other attributes and name forms, these situations are not covered.
Such complex mapping situations MAY be covered by extending this XML schema or by defining a more versatile context information schema.
-
-
4. Security Considerations
-
This extension allows a CA to outsource the process used to identify and authenticate a subject to another trust infrastructure in a dynamic manner that may differ from certificate to certificate. Since the authentication context is explicitly declared in the certificate, one certificate may be issued with a lower level of assurance than another, even though both have the same Issuer.
This means that a relying party needs to be aware of the certificate policy under which this CA operates in order to understand when the certificate provides a level of assurance with regard to subject authentication that is higher than the lowest provided level. A relying party that is not capable of understanding the information in the authentication context extension MUST assume that the certificate is issued using the lowest allowed level of assurance declared by the policy.

Appendix B. SAML Authentication Context Info XML Schema
-
This appendix contains an XML schema ([Schema1] [Schema2]) for the SAML Authentication context information defined in Section 3.
IMPORTANT NOTE:
-
-
-
-
The XML Schema in Appendix B.1 specifies a URL on rows 9 and 10 to the SAML schemaLocation (http://docs.oasis-open.org/security/saml/v2.0/ saml-schema-assertion-2.0.xsd), which is too long to fit into one row and therefore contains a line break. This line break has to be removed before this schema can be successfully compiled.
