Abstract
Authentication of a user or a wireless transmit/receive unit may be based on an obtained measure of authentication strength, which may referred to as an assurance level. For example, a user, via a WTRU, may request access to a service controlled by an access control entity (ACE). The user may be authenticated with a user authenticator and assertion function (UAAF), producing a result. A user assertion may be provided that includes the user authentication result, a user assurance level, and/or a user freshness level. The WTRU may be authenticated with a device authenticator and assertion function (DAAF), producing an associated result. A device assertion may be provided that may include the device authentication result, a device assurance level, and/or a device freshness level. The assertions may be bound together to receive access to a service or resource.
