    Abstract: An improvement to a graphics controller to prevent the contents of selected portions of the frame buffer from being read by devices external to the graphics controller. The invention defines one or more viewable rectangles in the frame buffer as a protected write-only area. Any attempt to read data from the protected area of the frame buffer triggers a security violation which can delete or destroy the contents of that area to prevent it from being read. The controller can also operate in a bypass mode in which the security functions are bypassed so the graphics controller operates in a conventional manner. A security violation may return the controller to the bypass mode. The invention can prevent protected data, such as copyrighted data downloaded over the Internet, from being copied from the frame buffer and use in an unauthorized manner.

    Abstract translation: 对图形控制器的改进以防止帧缓冲器的选定部分的内容被图形控制器外部的设备读取。 本发明将帧缓冲器中的一个或多个可视矩形定义为受保护的只写区域。 任何从帧缓冲区的保护区读取数据的尝试都会触发安全性冲突,可能会删除或破坏该区域的内容以防止其被读取。 控制器还可以在旁路模式下操作,其中安全功能被旁路,使得图形控制器以常规方式操作。 安全违规可能会使控制器返回到旁路模式。 本发明可以防止受保护的数据,例如通过因特网下载的受版权保护的数据从帧缓冲器中复制并以未经授权的方式使用。

    Abstract: An approach for providing Subscriber Identity Module (SIM) capabilities in an open platform without the need for a discrete, physical SIM device. For one aspect, a computing system provides for secure provisioning of SIM data and algorithms, for example, protected storage of SIM secret data objects, and protected execution of SIM algorithms that provide for Authentication, Authorization and Accounting (AAA) capabilities currently associated with discrete hardware SIM devices.

    Abstract: For one embodiment of the present invention, a protected storage device of a computer system includes a password stored therein. Instructions may be included on the computer system to authenticate the user. Once authenticated, the password may be transferred to a hard drive where it may be used to unlock the drive. Subsequent to unlocking the drive, an operating system may be loaded. For one embodiment of the present invention, the drive may be relocked by reducing the voltage supplied to the drive in accordance with a power management policy. The drive may be again unlocked by re-authenticating the user and transferring the password from protected storage to the drive.
