Computing platform security methods and apparatus

A tangible computer readable storage device or storage disk comprising instructions to cause a machine to at least:

• establish a trusted channel between a graphics driver and an application driver via mutual authentication of the graphics driver and the application driver;
• offload a task to a graphics processor, via the trusted channel, the task associated with the application driver;
• and
• configure a hypervisor to:
• generate an isolated first section of memory that is not visible to an operating system and isolated from an unprivileged second section of memory;
• designate the isolated first section of memory for execution of the offloaded computing task;
• cause the unprivileged second section of memory to be used for execution of display tasks;
• and
• monitor the isolated first section of memory for an unauthorized memory access attempt associated with the offloaded task, wherein the unprivileged second section of memory is designated for execution of display tasks.

A method comprising:

• establishing a trusted channel between a graphics driver and an application driver via mutual authentication of the graphics driver and the application driver;
• offloading, via the trusted channel, a computing task associated with the application driver to a graphics processor;
• and
• configuring, by executing an instruction with a second processor, a monitor to:
• generate an isolated first section of memory that is not visible to an operating system and isolated from an unprivileged second section of memory;
• designate the isolated first section of memory for execution of the offloaded computing task;
• cause the unprivileged second section of memory to be used for execution of display tasks;
• and
• monitor the isolated first section of memory associated with the offloaded computing task for an unauthorized access attempt, wherein the unprivileged second section of memory is designated for execution of display tasks.
