Abstract: The present disclosure provides RNG states. Generating the RNG states can include creating a first VM with a first RNG state and a second VM with a second RNG state and generating a plurality of interrupts for the first VM and the second VM. Generating the RNG states can also include providing the plurality of interrupts to the first VM with a first plurality of time intervals between the plurality of interrupts to configure the first RNG state and providing the plurality of interrupts to the second VM with a second plurality of time intervals, between the plurality of interrupts, that are different from the first plurality of time intervals to configure the second RNG state to be different from the first RNG state

Abstract: Embodiments of an invention for protecting supervisor mode information are disclosed. In one embodiment, an apparatus includes a storage location, instruction hardware, execution hardware, and control logic. The storage location is to store an indicator to enable supervisor mode information protection. The instruction hardware is to receive an instruction to access supervisor mode information. The execution hardware is to execute the instruction. The control logic is to prevent execution of the instruction if supervisor mode information protection is enabled and a current privilege level is less privileged than a supervisor mode.
