Secure memory repartitioning technologies are described. A processor includes a processor core and a memory controller coupled between the processor core and main memory. The main memory includes a memory range including a section of convertible pages are convertible to secure pages or non-secure pages. The processor core, in response to a page conversion instruction, is to determine from the instruction a convertible page in the memory range to be converted and convert the convertible page to be at least one of a secure page or a non-secure page. The memory range may also include a hardware reserved section are convertible in response to a section conversion instruction.

A device and method for securely rendering content on a gesture-enabled computing device includes initializing a secure execution environment on a processor graphics of the computing device. The computing device transfers view rendering code and associated state data to the secure execution environment. An initial view of the content is rendered by executing the view rendering code in the secure execution environment. A gesture is recognized, and an updated view of the content is rendered in the secure execution environment in response to the gesture. The gesture may include a touch gesture recognized on a touch screen, or a physical gesture of the user recognized by a camera. After the updated view of the content is rendered, the main processor of the computing device may receive updated view data from the secure execution environment.
