Internet Engineering Task Force (IETF) L. Johansson Request for Comments: 6711 NORDUNet Category: Informational August 2012 ISSN: 2070-1721 An IANA Registry for Level of Assurance (LoA) Profiles Abstract This document establishes an IANA registry for Level of Assurance (LoA) Profiles. The registry is intended to be used as an aid to discovering such LoA definitions in protocols that use an LoA concept, including Security Assertion Markup Language (SAML) 2.0 and OpenID Connect.

Informative References .....................................7 1. Introduction This document establishes an IANA registry for Level of Assurance (LoA) Profiles. [SAML] provides the following definition of the concept of "level of assurance": Many existing (and potential) SAML federation deployments have adopted a "levels of assurance" (or LOA) model for categorizing the wide variety of authentication methods into a small number of levels, typically based on some notion of the strength of the authentication. Federation members (service providers or "relying parties") then decide which level of assurance is required to access specific protected resources, based on some assessment of "value" or "risk". Another definition of an "assurance level" is given in RFC 4949 [RFC4949], which also identifies the roots of such profiles in the NIST special publication series, in particular SP 800-63 [SP63]. Level of Assurance Profiles are used in various protocols, including the Security Assertion Markup Language (SAML) version 2.0 and OpenID Connect. Several so-called trust frameworks and identity federations now exist, some of which define one or more LoAs. The purpose of this specification is to create an IANA registry where such LoA definitions can be discovered. While the quote above references SAML, the notion of a level of assurance has gained widespread acceptance and should be treated as a protocol-independent concept. The newly created IANA registry attempts to reflect this.
