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. Example PVM operations bring devices into a secure target state before allowing connectivity and access to a core network.

Platform validation and management of wireless devices

An electronic device having enhanced search capability, the electronic device having executable instructions in device memory and a human-readable display. The device comprises in the memory an electronic source file of an electronic document, the electronic document comprising first and second searchable terms, the first searchable term at a first portion of the electronic document being selectable by a human reader without the human reader manually entering in the first searchable term, and the second searchable term being selectable by a human reader. Upon selection by the human reader of the first and second searchable terms, the executable instructions cause to be displayed on the display screen a second portion of the electronic document wherein the first and second search terms occur. The enhanced device can be an enhanced e-book comprising a source file of a base work and electronically accessible context-specific information. The enhanced device can be an enhanced e-book comprising a display screen, memory, and executable instructions in the memory for displaying on the display screen text from a source file of a base work in an electronic source file readable by the enhanced e-book reader. The base work can have at least one selectable term, which upon selection by a human reader of the selectable term there can appear displayed on the display screen the context-specific information relating to the selectable term.

A method for installing embedded firmware is provided. The method includes generating one or more firmware file instances and generating one or more digital certificate instances that are separate instances from the firmware file instances. The method includes associating the one or more digital certificate instances with the one or more firmware file instances to facilitate updating signature-unaware modules with signature-aware firmware or to facilitate updating signature-aware modules with signature-unaware firmware.

Methods for firmware signature

Media content is delivered to a variety of mobile devices in a protected manner based on client-server architecture with a symmetric (private-key) encryption scheme. A media preparation server (MPS) encrypts media content and publishes and stores it on a content delivery server (CDS), such as a server in a content distribution network (CDN). Client devices can freely obtain the media content from the CDS and can also freely distribute the media content further. They cannot, however, play the content without first obtaining a decryption key and license. Access to decryption keys is via a centralized rights manager, providing a desired level of DRM control.

Methods and apparatus for verifying a boot process of a computing system are disclosed. An example computer-implemented method includes reading, by a computing system during a boot process, a header section of a read-write portion of firmware of the computing system. The example method further includes generating, using a first cryptographic hash algorithm, a message digest corresponding with the header. The example method also includes decrypting, using a first public-key, an encrypted signature corresponding with the header. The example method still further includes comparing the message digest corresponding with the header and the decrypted signature corresponding with the header. In the event the message digest corresponding with the header and the decrypted signature corresponding with the header match, the example method includes continuing the boot process. In the event the message digest corresponding with the header and the decrypted signature corresponding with the header do not match, the example method includes halting the boot process.

Firmware verified boot

An electronic gaming machine (EGM) comprises a memory storing boot program code comprising first code; a central processing unit (CPU) arranged to access the memory and initiate a boot process by reading the first code from the memory; and a monitoring device having or with access to validation code and arranged to take at least one protective action if the first code does not match the validation code.

Content control programme 14 for electronic book system 10 includes an automatic shutdown feature 31 which issues a shutdown request 40 in response to the state of the display 65. Prior to shutdown, the system 10 enters a post read sequence 36 which is configurable by a user. The programme 14 also provides other enhanced functions including the control of access to supplemental information 34 by linking of that information to the book content 15, and the generation of lists 61 by selection of material on the display.

A method of protecting game program code of an electronic gaming machine (EGM) comprising: determining prior to execution of the game program code whether there is a dongle in data communication with the EGM that contains a valid game token corresponding to the game program code; and taking at least one protective action if a valid game token is not located.

A method of protecting game program code (235) of an electronic gaming machine (EGM) (200) comprising: determining prior to execution of the game program code (235) whether there is a dongle (275) in data communication with the EGM that contains a valid game token corresponding to the game program code; and taking at least one protective action if a valid game token is not located.

Shared memory machines have two major overheads: keeping caches coherent and managing the multiple threads of computation which enable tolerance of very long memory latencies. Thetis is a hybrid architecture providing both shared memory and efficient message passing; it will be built from 'commodity' components and consists of sites with a small number of computation processors and a separate, programmable, auxiliary processor. The auxiliary processor performs overhead tasks, e.g. maintenance of cache directories, management of memory and thread queues; placed on its own bus, it does not block or delay memory accesses from computation processors which are not waiting for it. We describe how the use of a threaded variant of C (which has a functional style) enables the run-time system to dynamically determine coherence needs-dramatically reducing the overhead of maintaining coherent caches in a shared memory machine.
