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.
A system comprising a memory and a trusted execution environment (TEE), the TEE to:
A method performed by a trusted execution environment (TEE), the method comprising:
A non-transitory computer-readable medium containing instructions that, when executed by execution circuitry comprising a trusted execution environment (TEE), cause the TEE to respond by:
