  • Patent number: 9380024
    Abstract: Systems, methods, and apparatus are provided for generating verification data that may be used for validation of a wireless transmit-receive unit (WTRU). The verification data may be generated using a tree structure having protected registers, represented as root nodes, and component measurements, represented as leaf nodes. The verification data may be used to validate the WTRU. The validation may be performed using split-validation, which is a form of validation described that distributes validation tasks between two or more network entities. Subtree certification is also described, wherein a subtree of the tree structure may be certified by a third party.

  • Patent number: 9363676
    Abstract: One or more wireless communications device may include one or more domains that may be owned or controlled by one or more different owners. One of the domains may include a security domain having ultimate control over the enforcement of security policies on the one or more wireless communications devices. Another one of the domains may include a system-wide domain manager that is subsidiary to the security domain and may enforce the policies of one or more subsidiary domains. The system-wide domain manager may enforce its policies based on a privilege level received from the security domain. The privilege level may be based on the level of trust between an external stakeholder, such as an owner of a domain that is subsidiary to the system-wide domain manager, and the security domain.

  • Publication number: 20160087957
    Abstract: As users gain access to different services, the grade of the services may vary, for example, from low value services to high value services. A low value may indicate that a low strength of authentication is required, while a high value may indicate that a high strength of authentication is required to access the service. There is disclosed a method for authenticating a device comprising the determination (204) of an authentication requirement to access a first service that is provided by a service provider, SP, the discovery (208) of one or more authentication factors, associated with the device or the user, that are available for the authentication, the determination (210) whether at least one of the discovered authentication factors are sufficient to achieve the authentication requirement and, if so, the performance (212-228) of corresponding authentication procedures.

  • Publication number: 20160073262
    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.

  • Patent number: 9237142
    Abstract: A user of a mobile communications device may access services in a target domain using a source domain identity that is used to access services in a source domain. To enable such a use of the source domain identity in the target domain, the source domain identity may first be enrolled in the target domain. The enrollment may be facilitated by an enrollment entity at the target domain, such as a gateway or an OpenID server for example. The enrollment entity may establish a secure channel with the user's device for enabling enrollment of the source domain identity. Once enrolled, the source domain identity may be used for authentication of the user in the target domain. Enrollment of the source domain identity and/or authentication of the user based on the enrolled source domain identity may be implemented using a local OpenID provider (OP) residing on the user's device.

  • Publication number: 20150326561
    Abstract: Persistent communication layer credentials generated on a persistent communication layer at one network may be leveraged to perform authentication on another. For example, the persistent communication layer credentials may include application-layer credentials derived on an application layer. The application-layer credentials may be used to establish authentication credentials for authenticating a mobile device for access to services at a network server. The authentication credentials may be derived from the application-layer credentials of another network to enable a seamless handoff from one network to another. The authentication credentials may be derived from the application-layer credentials using reverse bootstrapping or other key derivation functions. The mobile device and/or network entity to which the mobile device is being authenticated may enable communication of authentication information between the communication layers to enable authentication of a device using multiple communication layers.

  • Publication number: 20150172269
    Abstract: Wireless telecommunications networks may implement various forms of authentication. There are a variety of different user and device authentication protocols that follow a similar network architecture, involving various network entities such as a user equipment (UE), a service provider (SP), and an authentication endpoint (AEP). To select an acceptable authentication protocol or credential for authenticating a user or UE, authentication protocol negotiations may take place between various network entities. For example, negotiations may take place in networks implementing a single-sign on (SSO) architecture and/or networks implementing a Generic Bootstrapping Architecture (GBA).

  • Patent number: 9032473
    Abstract: Systems, methods, and instrumentalities are disclosed that allow a user to initiate migration of a credential from one domain to another domain. A request to initiate a migration of credentials from a first domain to a second domain may be initiated by a user (1a.). A remote owner may receive a message indicating that the migration has been requested. The message received by the remote owner may be an indication that the source and destination devices have performed internal checks and determined that a migration could proceed. The remote owner may evaluate source information received from the source device and destination information received from the destination device (6), (6a.), (6b.). Based on the evaluation of the source information and the destination information, the remote owner may determine that the migration is acceptable. The remote owner may send an indication to proceed with the migration (7), (7a).

  • Publication number: 20150099510
    Abstract: A wireless communications device may be configured to perform integrity checking and interrogation with a network entity to isolate a portion of a failed component on the wireless network device for remediation. Once an integrity failure is determined on a component of the device, the device may identify a functionality associated with the component and indicate the failed functionality to the network entity. Both the wireless network device and the network entity may identify the failed functionality and/or failed component using a component-to-functionality map. After receiving an indication of an integrity failure at the device, the network entity may determine that one or more additional iterations of integrity checking may be performed at the device to narrow the scope of the integrity failure on the failed component. Once the integrity failure is isolated, the network entity may remediate a portion of the failed component on the wireless communications device.

  • Publication number: 20150067813
    Abstract: Systems, methods, and instrumentalities are disclosed that may provide for integration of trusted OpenID (TOpenID) with OpenID. The authentication may be accomplished, in part, via communications between a trusted ticket server on a UE and a network application function. The UE may retrieve platform validation data (e.g., from a trusted platform module on the UE). The UE may receive a platform verification in response to the platform validation data. The platform verification may indicate that the network application function has verified the platform validation data and the user. The platform verification may indicate that the platform validation data matches a previously generated reference value.
