    Abstract: 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.

    Abstract: A method and system is disclosed for transforming of data by a DMA controller (202) without first saving the transmitted data on an intermediate medium. The method includes the DMA controller (202) accessing data for transfer between an origination location in the system and a destination location in the system. The accessed data is passed through the DMA controller (202) before being sent to the destination location. While the data is being passed through the DMA controller (202), it is transformed into a modified state. This transformation may include encryption or decryption of the data. The transformation may also include adding error correction bits to the data through an encoding process or decoding previously encoded data. Upon completion of the transformation, the data is sent directly to a prescribed destination location, typically either a memory circuit or an I/O device. Also disclosed is a DMA controller (202) capable of performing the data transformation.

    Abstract translation: 公开了一种用于通过DMA控制器（202）转换数据而不首先在中间介质上保存所发送的数据的方法和系统。 该方法包括DMA控制器（202）访问用于在系统中的发起位置和系统中的目的地位置之间传送的数据。 访问的数据在被发送到目的地位置之前通过DMA控制器（202）传送。 当数据通过DMA控制器（202）时，它被转换成修改状态。 该变换可以包括数据的加密或解密。 该变换还可以包括通过编码处理或对先前编码的数据解码来向数据添加纠错位。 完成变换后，数据直接发送到规定的目的地位置，通常是存储器电路或I / O设备。 还公开了能够执行数据变换的DMA控制器（202）。

    Abstract: A method and an apparatus for executing codes embedded inside a device to verify a code image loaded in a memory of the device are described. A code image may be executed after being verified as a trusted code image. The embedded codes may be stored in a secure ROM (read only memory) chip of the device. In one embodiment, the verification of the code image is based on a key stored within the secure ROM chip. The key may be unique to each device. Access to the key may be controlled by the associated secure ROM chip. The device may complete establishing an operating environment subsequent to executing the verified code image.

    Abstract: A method and an apparatus for configuring a key stored within a secure storage area (e.g., ROM) of a device including one of enabling and disabling the key according to a predetermined condition to execute a code image are described. The key may uniquely identify the device. The code image may be loaded from a provider satisfying a predetermined condition to set up at least one component of an operating environment of the device. Verification of the code image may be optional according to the configuration of the key. Secure execution of an unverified code image may be based on a configuration that disables the key.

    Abstract: A method and apparatus for executing a first executable code image having a first version number into a memory of a device in an attempt to establish an operating environment of the device are described. The first executable code image retrieves a second version number from the second executable code image after successfully authenticating the second executable code image. If the first version number and the second version number do not satisfy a predetermined relationship, the second executable code image is prevented from being loaded by the first executable code image.

    Abstract: 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.
