摘要:
A method and apparatus for securely booting software components in an electronic device to establish an operating environment are described herein. According to an aspect of the invention, software components are to be executed in sequence in order to establish an operating environment of a device. For each software component, a security code is executed to authenticate and verify an executable code image associated with each software component using one or more keys embedded within a secure ROM (read-only memory) of the device and one or more hardware configuration settings of the device. The security code for each software component includes a common functionality to authenticate and verify the executable code image associated with each software component. In response to successfully authenticating and verifying the executable code image, the executable code image is then executed in a main memory of the device to launch the associated software component.

A method and apparatus for personalizing a software component to be executed in particular environment are described herein. According to an aspect of the invention, in response to an executable code image representing a software component to be installed in an electronic device, the executable code image is encrypted using an encryption key. The encryption key is then wrapped with a UID that uniquely identifies the electronic device, where the UID is embedded within a secure ROM of the electronic device. The wrapped encryption key and the encrypted executable code image are then encapsulated into a data object to be stored in a storage of the electronic device, such that when the electronic device is subsequently initialized for operation, the executable code image can only be recovered using the UID of the electronic device to retrieve a decryption key in order to decrypt the executable code image.
摘要:
A request for a high voltage mode is received and a high voltage timer is started in response to determining that a remaining amount of high voltage credits exceeds a voltage switch threshold value. A switch to the high voltage mode is made in response to the request. A low voltage mode is switched to in response to an indication. The request may be received from an application running on a data processing system. If the indication is that the high voltage timer has expired, a low voltage timer is started in response to switching to low voltage mode. If the high voltage request is still active when the low voltage timer expires, a switch back to high voltage mode occurs and a new high voltage timer is started.

A process and apparatus for configuring one or more integrated circuits within a device in a manufacturing process is described. In an exemplary process, a device is manufactured by assembling a chip onto a board such as a printed circuit substrate and the chip is fused from power routed across the board to the chip. The power source for the fusing can be generated from the internal power supply on the board or received on a test point on the board itself or a connection interface (e.g. a USB interface) coupled to the board. In an exemplary apparatus, a device comprises a chip with a plurality of fuses that are used to configure the device and a board coupled to the chip, with the board capable of routing power from the board to the chip and the power is used to blow one or more of the plurality of fuses.

An improved architecture for a program code conversion apparatus and method for generating intermediate representations for program code conversion. The program code conversion apparatus determines which types of IR nodes to generate in an intermediate representation (IR) of subject code (10) to be translated. Depending upon the particular subject and target computing environments involved in the conversion, the program code conversion apparatus utilizes either base nodes, complex nodes, polymorphic nodes, and architecture specific nodes, or some combination thereof, in generating the intermediate representation.
摘要:
A method is described that involves detecting the presence of a pairing partner. Prior to establishing a paired relationship with the pairing partner, a user is prompted to verify himself/herself. In response to the user properly verifying himself/herself, the paring partner is paired with. The pairing includes invoking a remote storage protocol that contemplates a network between the partners to establish on a first of the partners access to non volatile storage resources for general use. The non volatile storage resources are located on a second of the partners. The second of the partners is a handheld device that provides wireless cell phone service, wireless Internet service and music playback service.
