    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.

    Abstract: A method and apparatus to establish a trustworthy local time based on trusted computing methods are described. The concepts are scaling because they may be graded by the frequency and accuracy with which a reliable external time source is available for correction and/or reset, and how trustworthy this external source is in a commercial scenario. The techniques also take into account that the number of different paths and number of hops between the device and the trusted external time source may vary. A local clock related value which is protected by a TPM securely bound to an external clock. A system of Accuracy Statements (AS) is added to introduce time references to the audit data provided by other maybe cheaper sources than the time source providing the initial time.

    Abstract translation: 描述了基于可信计算方法建立可靠的本地时间的方法和装置。 概念是缩放，因为它们可以通过可靠的外部时间源可用于校正和/或重置的频率和准确度进行分级，并且在商业场景中该外部源是如何可信赖的。 这些技术还考虑到设备与受信任的外部时间源之间的不同路径和跳数的数量可能会有所不同。 由TPM保护的本地时钟相关值安全地绑定到外部时钟。 添加准确性声明（AS）的系统来引入时间参考，以提供其他可能比提供初始时间的时间源更便宜的源提供的审计数据。

    Abstract: A wireless device may perform a local authentication to reduce the traffic on a network. The local authentication may be performed using a local web server and/or a local OpenID provider (OP) associated with the wireless device. The local web server and/or local OP may be implemented on a security module, such as a smartcard or a trusted execution environment for example. The local OP and/or local web server may be used to implement a provisioning phase to derive a session key, associated with a service provider, from an authentication between the wireless device and the network. The session key may be reusable for subsequent local authentications to locally authenticate a user of the wireless device to the service provider.
