Abstract

Computing platform security methods and apparatus are disclosed. An example apparatus includes a graphics processor; and a graphics driver to facilitate access to the graphics processor, the graphics driver including: an authenticator to establish a trusted channel between the graphics driver and an application driver via mutual authentication of the graphics driver and the application driver; an offloader to offload a computing task to the graphics processor via the trusted channel, the computing task associated with the application driver; and a hypervisor to monitor memory associated with the offloaded computing task for an unauthorized access attempt.
