International Classification:

G06F 9/00

US Classification:

713168, 713182, 713185, 726 2

Abstract:

Under the direction of a first party, an integrated circuit (IC) device is configured to temporarily enable access to a debug interface of the IC device via authentication of the first party by a challenge/response process using a key of the IC device and a challenge value generated at the IC device. The first party then may conduct a software evaluation of the IC device via the debug interface. In response to failing to identify an issue with the IC device from the software evaluation, the first party can permanently enable open access to the debug interface while authenticated and provide the IC device to a second party. Under the direction of the second party, a hardware evaluation of the IC device is conducted via the debug interface that was permanently opened by the first party.

International Classification:

H04L 9/32

US Classification:

713168

Abstract:

Methods, components and apparatus for implementing platform validation and management (PVM) are disclosed. PVM provides the functionality and operations of a platform validation entity with remote management of devices by device management components and systems such as a home node-B management system or component.

International Classification:

G06F 21/20

US Classification:

726 6

Abstract:

Integrity validation of a network device may be performed. A network device comprising a secure hardware module, may receive a root key. The secure hardware module may also receive a first code measurement. The secure hardware module may provide a first key based on the root key and the first code measurement. The secure hardware module may receive a second code measurement and provide a second key based on the first key and the second code measurement. The release of keys based on code measurements may provide authentication in stages.

G06F 15/16

US Classification:

726 1

Abstract:

Systems, methods, and instrumentalities are disclosed that provide for a gateway outside of a network domain to provide services to a plurality of devices. For example, the gateway may act as a management entity or as a proxy for the network domain. As a management entity, the gateway may perform a security function relating to each of the plurality of devices. The gateway may perform the security function without the network domain participating or having knowledge of the particular devices. As a proxy for the network, the gateway may receive a command from the network domain to perform a security function relating to each of a plurality of devices. The network may know the identity of each of the plurality of devices. The gateway may perform the security function for each of the plurality of devices and aggregate related information before sending the information to the network domain.

US Classification:

726 1

Abstract:

Systems, methods, and apparatus are disclosed for coordinating enforcement of policies on a network and/or a wireless transmit/receive unit. The policies may include stakeholder-specific policies of one or more stakeholders that provide services on a user equipment. Enforcement of the stakeholder-specific policies may be securely coordinated using a policy coordination function.

US Classification:

714 411, 714 2, 714 41, 714 37, 714E11023, 714E11073, 714E11178

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.
