15 Claims

1. An apparatus comprising:

processor circuitry coupled with a memory, the processor circuitry to:

configure a key based on a key ID associated with a trusted execution environment (TEE) virtual machine (VM) and instruct a memory device to configure a memory encryption engine (MEE) of the memory device based on the key and allocation of remote memory in the memory device;

initialize the allocated remote memory using the key; and

enable secure access by the TEE VM to the allocated remote memory over a system interconnect by encrypting or decrypting data transfers between the TEE VM and the memory device using the key.
