Abstract: A handheld wireless communication device (HWCD) establishes an ad hoc network comprising interconnected networks for a user. The HWCD gains access to content on a first device and controls communication of the content from the first device via the HWCD to a second device. The HWCD enables the second device to consume the content. The content may be streamed from the first device via the HWCD to the second device. The first device is a service provider network device or other network device. The access may be authenticated and/or secure. Secure access to the content is extended from the first device to the second device. The ad hoc network is configured and/or reconfigured until communication is complete. The HWCD comprises multiple wireless interfaces. The ad hoc network comprises a PAN, WLAN, WAN and/or cellular network. The HWCD may hand-off among base stations during communication of the content.

Abstract: Methods and systems are provided that use smartcards, such as subscriber identity module (SIM) cards to provide secure functions for a mobile client. One embodiment of the invention provides a mobile communication network system that includes a mobile network, a mobile terminal, a server coupled to the mobile terminal via the mobile network, and a subscriber identity module (SIM) card coupled to the mobile terminal. The SIM card includes a first key and a second key. The first key is used to authenticate an intended user of the mobile terminal to the mobile network. Upon successful authentication of the intended user to the mobile network, the mobile terminal downloads a function offered from the server through the mobile network. The second key is then used by the mobile terminal to authenticate the intended user to the downloaded function so that the intended user can utilize the function.

Abstract: Wireless mobile communication (WMC) devices located in operating proximity of each other may be enabled to form a mesh (ad hoc wireless) network. WMC devices in a mesh network may form a queuing system wherein each WMC device may store data forwarded to and/or from other WMC devices in the mesh network. Each WMC device in the mesh network may have different queuing capability based on a plurality of factors that may comprise internal factors such as processing, storage, power, and/or connectivity. The mesh network may comprise an internal addressing scheme that may enable utilization of the queuing system whether or not WMC devices in the mesh network are communicatively coupled to external networks.

Abstract: A device may include countermeasure circuitry that provides a countermeasure check that protects device logic. The device may also include enforcement circuitry that non-deterministically enforces the countermeasure check on the device logic so that the device logic is not always protected by a countermeasure action within the countermeasure check. The device may non-deterministically enforce the countermeasure check according to an enforcement rate, and the device may adjust the enforcement rate depending on a priority of the device logic or device logic portion protected by a particular countermeasure check.
