  • 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.

  • Patent number: 9178580
    Abstract: A method and apparatus for selecting an antenna mapping in multiple-in/multiple-out (MIMO) enabled wireless communication networks. A candidate set of currently available antenna mappings is determined based upon measured long term channel conditions. An antenna mapping is selected from the candidate set, and the mapping is calibrated with a selected antenna mapping of a receiving wireless transmit/receive unit (WTRU). When the selected mappings are calibrated, packet data transmission begins. In an alternative embodiment, a calibration training frame (CTF) is used to calibrate multiple antenna mappings simultaneously or sequentially. Also disclosed are physical layer and medium access control layer frame formats for implementing antenna mapping selection according to the invention.

  • 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: 9036821
    Abstract: A secret stream of bits begins by receiving a public random stream contained in a wireless communication signal at a transmit/receive unit. The public random stream is sampled and specific bits are extracted according to a shared common secret. These extracted bits are used to create a longer secret stream. The shared common secret may be generated using JRNSO techniques, or provided to the transmit/receive units prior to the communication session. Alternatively, one of the transmit/receive unit is assumed to be more powerful than any potential eavesdropper. In this situation, the powerful transmit/receive unit may broadcast and store a public random stream. The weaker transmit/receive unit selects select random bits of the broadcast for creating a key. The weaker transmit/receive unit sends the powerful transmit/receive unit the selected bit numbers, and powerful transmit/receive unit uses the random numbers to produce the key created by the weaker transmit/receive unit.
