Abstract:
1. A method of secure information processing, the method comprising: configuring one or more computing components associated with video frame buffer management such that isolation between domains or virtual machines is established as a function of presenting, to each operating system associated with each of the domains or virtual machines, a physical frame buffer as a memory area in a physical graphics device frame buffer to display data on a physical graphics device; processing information associated with input devices while keeping the domains or virtual machines separate; performing navigation among the domains or virtual machines as a function of securely changing information displayed on the physical graphics device; isolating one or more of the physical frame buffers via resource isolation features of a separation kernel such that secure isolation between the domains or virtual machines is maintained; and processing information via a Keyboard Video Mouse (KVM) component included within a Virtual Device Server, wherein the KVM component has access to input from a physical input device.
