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: Disclosed embodiments relate to encoded inline capabilities. In one example, a system includes a trusted execution environment (TEE) to partition an address space within a memory into a plurality of compartments each associated with code to execute a function, the TEE further to assign a message object in a heap to each compartment, receive a request from a first compartment to send a message block to a specified destination compartment, respond to the request by authenticating the request, generating a corresponding encoded capability, conveying the encoded capability to the destination compartment, and scheduling the destination compartment to respond to the request, and subsequently, respond to a check capability request from the destination compartment by checking the encoded capability and, when the check passes, providing a memory address to access the message block, and, otherwise, generating a fault, wherein each compartment is isolated from other compartments.
