    摘要： A processor includes a feature control unit to enable or disable one or more processor features individually in response to a user selectable setting. The feature control unit is adapted to disable the processor feature(s) if the user setting has not been updated in accordance with an input regardless of the value of the user setting prior to the update and to enable or disable the processor feature(s) in accordance with the updated user setting after it has been updated. The feature control unit may also include a lock unit to prevent changes to the updated user setting and a software feature selection unit to enable or disable processor features in response to a software feature selection setting and, optionally, only enable or disable processor features whose corresponding updated user setting is user enabled. The feature control unit may also include mechanisms to detect illegal feature selection conditions.

    摘要： Delivering a Direct Proof private key to a device installed in a client computer system in the field may be accomplished in a secure manner without requiring significant non-volatile storage in the device. A unique pseudo-random value is generated and stored in the device at manufacturing time. The pseudo-random value is used to generate a symmetric key for encrypting a data structure holding a Direct Proof private key and a private key digest associated with the device. The resulting-encrypted data structure is stored on a removable storage medium (such as a CD), and distributed to the owner of the client computer system. When the device is initialized on the client computer system, the system checks if a localized encrypted data structure is present in the system. If not, the system obtains the associated encrypted data structure from the removable storage medium. The device decrypts the encrypted data structure using a symmetric key regenerated from its stored pseudo-random value to obtain the Direct Proof private key. If the private key is valid, it may be used for subsequent authentication processing by the device in the client computer system.
